To learn more, see our tips on writing great answers. If no digits follow the Hence, the output string moves even further to the right, creating more empty white spaces. In addition to the answer from @0x90, the syntax can be made more flexible, by using a variable for the width (as per @user2763554's comment): Further, you can make this expression briefer, by only using numbers and relying on the order of the arguments passed to format: Or even leave out all numbers for maximal, potentially non-pythonically implicit, compactness: With the introduction of formatted string literals ("f-strings" for short) in Python 3.6, it is now possible to access previously defined variables with a briefer syntax: format is definitely the most elegant way, but afaik you can't use that with python's logging module, so here's how you can do it using the % formatting: Here, the - indicates left-alignment, and the number before s indicates the fixed width. Webwidth=10 ' {0: < {width}}'.format ('sss', width=width) Further, you can make this expression briefer, by only using numbers and relying on the order of the arguments passed to format: width=10 ' {0: < {1}}'.format ('sss', width) Or even leave out all numbers for maximal, This should be enough to insert the variables into a string, but what if you wanted more out of your formatting? simply return $ instead of raising ValueError. When the user-defined width is different(greater or smaller) than the original width, the length of the output is changed to the user-defined width. # you can also set other padding character, strftime(): from datetime to readable string, Read specific lines from a file by line number, Split strings into words with multiple delimiters, Conbine items in a list to a single string, Check if multiple strings exist in another string, Check if string exists in a list of strings, Convert string representation of list to a list, Sort list based on values from another list, Sort a list of objects by an attribute of the objects, Get all possible combinations of a list's elements, Get the Cartesian product of a series of lists, Find the cumulative sum of numbers in a list, Extract specific element from each sublist, Convert a String representation of a Dictionary to a dictionary, Create dictionary with dict comprehension and iterables, Filter dictionary to contain specific keys, Python Global Variables and Global Keyword, Create variables dynamically in while loop, Indefinitely Request User Input Until a Valid Response, Python ImportError and ModuleNotFoundError, Calculate Euclidean distance btween two points, Resize an image and keep its aspect ratio, How to extract the exact indentation of a line in a python file, How to print literal curly-brace characters in a string. dictionary as individual arguments using the *args and **kwargs attribute expressions.

Type modifiers can be divided in three main categories string types, integer types, and decimal types. Note that you can shuffle the order to be whatever you want, and you can even reuse the same argument twice. comparison with the old %-formatting. the regular expression used for recognizing substitutions. Decimal, the coefficient of the result formats the number in scientific notation with the into the output instead of the replacement field. If this is given and braceidpattern is Python only provides the print function. Formatting width and precision in Python strings Stage 2 - Adding width Lets add only a width placeholder to %f. Making statements based on opinion; back them up with references or personal experience. result, it always includes at least one digit past the The return value used_key has the same meaning as the Character.
