format()
format() is a Python function in the Built-in Functions category. Formats a value using a format specifier. The syntax is format(value, format_spec=""). Parameters: value — any value to format. Returns: Formatted string. A typical example: format(3.14159, ".2f") # "3.14"
format(255, "x") # "ff"
format(42, "b") # "101010". A close sibling is print(), which prints objects to the text stream, separated by `sep` and followed by `end`. A close sibling is len(), which returns the length (number of items) of an object. Works with sequences, collections, and strings. A close sibling is range(), which returns an immutable sequence of numbers. Commonly used in for loops. A close sibling is type(), which returns the type of an object, or creates a new type with three arguments.
