The function definition should be written before the function call. def is a keyword that tells Python a new function is being defined. You can place any arguments or input parameters should be placed within these parentheses. In this article, we'll examine the many ways we can write to a file with the print() function. We can use an if __name__ == "__main__" block to allow or prevent parts of code from being run when the modules are imported. They'll let you print the entire call stack, exception traces, etc. When the Python interpreter reads a file, the __name__ variable is set as __main__ if the module being run, or as the module's name if it is imported. Hence python does not support Function overloading.

Function name: print Imported function name: system. The items() or the iteritems() function can be utilized to get the variable name in the form of a string in Python. Among other things, this makes it possible to get the name of the current function or callers. Rule-2: Do not use uppercase character while naming a function in python. That said, Python does have built-in namespaces.For example, locals() will return a dictionary mapping a function's variables' names to their values, and globals() does the same for a module. The finally blocks will get executed even if the try block raises an exception message. I know this could be done in C using __func__ macro but I am not sure about python.
