In this scenario, we are calling a function from another file. Let us take acompute.pyfile having a functioninterestto compute the simple interest of given principal and duration. We will then write ademo.pyfile that has saving function, which when called makes call to interest function to ...
Whenever you call parent(), the inner functions first_child() and second_child() are also called. But because of their local scope, they aren’t available outside of the parent() function.Functions as Return ValuesPython also allows you to return functions from functions. In the following ...
The actual parameters (arguments) to a function call are introduced in the local symbol table of the called function when it is called; thus, arguments are passed usingcall by value(where thevalueis always an objectreference, not the value of the object).[1]When a function calls another fu...
