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. WebMar 29, 2024 · Python Function within Functions. A function that is defined inside another function is known as the inner function or nested function. Nested functions are able to access variables of the enclosing scope. Inner functions are used so that they can be protected from everything happening outside the function.
