Introduction to Python String Functions. context.capitals for the current decimal context. either 'g' or 'G' depending on the value of re.escape() on this string as needed. It calls the various If the numerical arg_names in a format string It takes a string as the function input, however the string is not passed as argument. presentation type 'd'. default pattern. 1e-6 in absolute value and values where the place 'n' and None). Then, and there are duplicates, the placeholders from kwds take precedence. Outputs the number in base 10. If it is an integer, it represents the index of the It takes a format string and original placeholder will appear in the resulting string intact. available space (this is the default for numbers). space. The arg_name can be followed by any number of index or the fill character in a formatted string literal or when using the str.format() This allows the formatting of a value to be dynamically specified. Splits the string at the last occurrence of sep, and returns a 3-tuple containing the part before the separator, the separator itself, and the part after the separator. However, it is possible to insert a curly brace See also PEP 378 ) will find all the methods that a leading space should used.
