WebIn Python, standard library functions are the built-in functions that can be used directly in our program. For example, print () - prints the string inside the quotation marks. sqrt () - returns the square root of a number. pow () - returns the power of a number. These library functions are defined inside the module. WebJan 17, 2013 · Simply -> is introduced to get developers to optionally specify the return type of the function. See Python Enhancement Proposal 3107. This is an indication of how things may develop in future as Python is adopted extensively - an indication towards strong typing - this is my personal observation.
