Depends on the text editor, browser, etc. But most cases it's 4 spaces. This is what official documentation saids: A new line character appropriate to the platform running the application. The Objective of the question is to use 'printf' statements. So during code testing, the JUnit Test looks only for the 'printf' statement. If you imagine a coaster as in the little bit of card where you put your cup when you're drinking something That's comparable to a formatter, in the sense that it shows the place you should put something.
The part means that: - : when s1 is put into this spot, keep it to the left side. The 03 part means that when x is put into this spot: 3 : it must take up three spaces. The default padder is whitespace " " if 0 is not used. Can you tell me please, where i can find some serious TuT Videos? I would love to learn this kind of things. Between, thanks for the clear explanation!
Thanks for your explaination. It really helped. It was clear and the best part was that you expained it by breaking it in parts Every letter in that segment. Very good explanation, I hope I can be better at understanding the syntax and implementing it in the future. Gosh, I was trying to use loops for it to find out how many spaces I need to add, and this turns out to be such a simple thing Thanks a lot.
I was wondering if someone can show me how to use the format method for Java Strings. For instance If I want the width of all my output to be the same. In this example, all the output are neatly formatted under each other; How would I accomplish this with the format method. I would also use the StringBuilder class too which is more efficient.
As a reference I recommend Javadoc on formatter syntax.Python Practice HackerRank - String Formatting

What do you actually want to know that the documentation and format string documentation aren't showing you? You appear to have been given a requirement you are reluctant to workout for yourself.
I can only assume this is homework? Sort of, this is only one problem in the program Im working on for my class. Active Oldest Votes. See the answers below for a better solution though Why not just generate a whitespace string dynamically to insert into the statement. So if you want them all to start on the 50th character Lukas Knuth The '-' makes the result left-justified. Julia 1 1 gold badge 6 6 silver badges 23 23 bronze badges. You can also use System. JustinHarris Just remember that subsequent System.
Is there a better solution? This answer is almost what OP is asking for. You should do System. You're also able to call System. If you want a minimum of 4 characters, for instance, System. I82Much I82Much I am not sure if that same "number of spaces" argument works for strings though. I can't say I've ever had to worry about my strings as I write them, but I use that argument for numbers all the time and I am pretty sure it results in leading 0s being added. I just tried this in IdeOne: ideone.

Welcome to Stack Overflow, Amol.As a continuation of the previous part of this series, I will be continuing to work through some Hackerrank challenges for Python 3, and compare the solutions to how I would solve them in a language I'm more proficient in, Perl 6.
In this post, I will work through some of the Python 3 string challenges from Hackerrank. Raiph posted a comment on Reddit suggesting a slightly different layout, which I will be using for this post. Additional comments are always welcome as I try to improve the format. Once again I'd like to make clear I'm trying to stick to the original Hackerrank challenges by not using any imports not specifically used in the original challenge.
If you have suggestions for Python 3 or Perl 6 modules to make a given task easier, I still appreciate them, but I won't update my solutions to use a module. This challenge involves a string containing spaces, where the spaces are to be replaced with dashes - instead. I personally am not too fond that join takes a list of words to join together, whereas split takes a word to split with.
It feels a little inconsistent. It also doesn't allow me to read the code logically from left to right. The Perl 6 solution to the challenge does the same as the Python variant. Even the function names are the same! The biggest difference is that I can chain the functions from left to right, leading to clearer code. The next challenge is a simply string formatting task. Before you begin, I know this can be done using f"" strings, and that was my first attempt to use as well.
However, Hackerrank did not accept this, complaining about invalid syntax, so I assume they're running an older Python 3 than I do. That said, this is a simple printf formatted string, which then accepts a tuple of arguments to put into the string.
Perl 6 has double-quote semantics that many people may be familiar with from other languages. When you insert a variable in a double-quoted string, it's. Str value will be used. That is to say, the value will be converted to a Str if required, and then put into the string. You are given a string stringan integer position and a character character. In stringreplace the character at position to the given character. The position is counted from starting point 0, so I don't have to think about differences between what a human or computer considers to be position 1 in a string.
This is basically what the example showed as well that came with the challenge, so wasn't too hard to solve. My only complaint was that I couldn't call my list "list", because that's a reserved keyword. The Perl 6 variant does the same things as the Python variant.
The challenge is to find how often a substring occurs in the string. If it does, I increment count by 1. Now, I learned that Python also has the inline ifjust like Perl 6 does, however, it also needs an else block.Please Login in order to post a comment. This line of code responses to this requirement: "Each value should be space-padded to match the width of the binary value of n.
Java Output Formatting
You can refer to the previous challenge. Basically it means adjusting to the right with width w and empty space filled with whitespace ie. Hey please help me out.
I have tried this on terminal and it works perfectly. I don't know why is it not passing through the test cases here:. The link pasted above answers your doubt the same link can be used to get started with python programming. Good luck :. The output for the oct for some reason has the letter 'o' adjacent to it, what is thre potential cause? For printing only deciaml it does print but its not working with binary, octahe and decmal.
This method lets us concatenate elements within a string through positional formatting. Hopefully this explains what I mean a bit more did this in a Python 3. Still a little unclear - why would it have to tell the format function to set width to the width at line 2?
It seems like width is being assigned twice here. First at line 2. Put in another way, how does format have no idea what width should be set to? Isn't width set in line 2 already?
It's because they're two different variables. Although not exactly the same, a similar example would be a variable defined in a function versus after and outside of one:. It takes the 'ith'value. He's referring to the 0 position argument in formatthis can be very useful, however is mostly left out from simple formatting to not clutter the code.
See this formatting scenario:. I am also using a variable to specify the width and align of each printed out "i" and then to also apply data type conversions on the fly. I agree that it's all about formatting. I like the example provided here because it's very concise like what I went with, although I would still shorten it a bit:. I ended up circling back to my first solution after trying several other approaches and then finally noticing an astray digit just before the binary conversion This doesn't work for testcase 2 even though it produces exactly the same and can be validated separately.
The separator between the arguments to print function in Python is space by default. It is also used for formatting the output strings. We can learn formatting in python in this site.
I tried to print the same and had got ox1, ox2 for printing octal numbers and similarly for hexadecimal values. So the given format is to exclude 0b. In your example: 0d for decimal.
Missed this one at first too. Ended up buying a test case to see what was up. A little misleading IMHO, both outputs should be acceptable.
Yea, had to buy a testcase as well. Lowercase hex is valid so maybe it should be stated explicitely that only uppercase hex is accepted as correct for this problem.An interpolated string is a string literal that might contain interpolation expressions. When an interpolated string is resolved to a result string, items with interpolation expressions are replaced by the string representations of the expression results. This feature is available starting with C 6.
String interpolation provides a more readable and convenient syntax to create formatted strings than a string composite formatting feature.
The following example uses both features to produce the same output:. For more information, see Escaping Braces. As the colon ":" has special meaning in an interpolation expression item, in order to use a conditional operator in an interpolation expression, enclose that expression in parentheses. The following example shows how to include a brace in a result string and how to use a conditional operator in an interpolation expression:.
For more information about verbatim strings, see the string and verbatim identifier topics. Starting with C 8. Conversion of an interpolated string to a String instance that is the result of interpolated string resolution with interpolation expression items being replaced with the properly formatted string representations of their results.
This conversion uses the CurrentCulture to format expression results. Conversion of an interpolated string to a FormattableString instance that represents a composite format string along with the expression results to be formatted. That allows you to create multiple result strings with culture-specific content from a single FormattableString instance. To do that, call one of the following methods:.
You also can use the ToString IFormatProvider method to provide a user-defined implementation of the IFormatProvider interface that supports custom formatting. For more information, see the Custom formatting with ICustomFormatter section of the Formatting types in. NET article. Conversion of an interpolated string to an IFormattable instance that also allows you to create multiple result strings with culture-specific content from a single IFormattable instance.
The following example uses implicit conversion to FormattableString to create culture-specific result strings:. If you are new to string interpolation, see the String interpolation in C interactive tutorial.
You also can check another String interpolation in C tutorial that demonstrates how to use interpolated strings to produce formatted strings. If an interpolated string has the type stringit's typically transformed into a String. Format method call. The compiler may replace String. Format with String. Concat if the analyzed behavior would be equivalent to concatenation. If an interpolated string has the type IFormattable or FormattableStringthe compiler generates a call to the FormattableStringFactory.
Create method. For more information, see the Interpolated strings section of the C language specification. You may also leave feedback directly on GitHub. Skip to main content.
Exit focus mode. Today is Wednesday, it's now. The following table describes each element: Element Description interpolationExpression The expression that produces a result to be formatted. String representation of null is String. If positive, the string representation is right-aligned; if negative, it's left-aligned. For more information, see Alignment Component. For more information, see Format String Component. The following example uses optional formatting components described above: Console.We have attached the Questions and Answers in a pdf format at free of cost.
