String formatting with format() As numbers, string can be formatted in a similar way with format(). Example 6: String formatting with padding and alignment # string padding with left alignment print("{:5}".format("cat")) # string padding with right alignment print("{:>5}".format("cat...
Right padding is analogous to left padding - the given character is added to the end of the string until the string reaches a certain length. Python Functions For String Padding Python offers many functions to format and handle strings, their use depends on the use case and the developer's ...

Perform a string formatting operation. The format_string argument can contain literal text or replacement fields delimited by braces {}. Each replacement field contains either the numeric index of a positional argument, or the name of a keyword argument. Returns a copy of format_string where each...
