String Formatting

String Formatting

The format() is one of the formatting methods in the string datatype Python programming language, which allows a range of substitutions and formatting. This method enables us to concatenate elements within a string through positional formatting. Python uses the string formatting method similar to C-style string formatting to create new, formatted strings. The "%" operator usually is used to format a set of variables enclosed in a fixed size list(tuple), together with a format string, which will contain normal text along with "argument specifiers", special symbols like "%s" and "%”. The format () method is the most flexible and useful method in formatting strings. The parenthesis {} are used as the placeholder in the string and are also replaced by the format () method argument.
