Calling one function from another is the same as calling a function from anywhere in the program, like we've already seen. Functions often call other functions, this is the way we write modular code which is both easy to debug and to extend.
We might also want to write private functions which indicate to other programmers that they shouldn't use the function externally. We might also want to nest our functions so their scope is very limited. In this video we look at examples of these three cases.
# Calling other Functions using Python 2.5
"""Use one leading underscore only for non-public
methods and instance variables."""
"Return the returned value of fn2"
answer = fn2()
# link for nested functions
Are you learning Python? To keep the site running clean and ad-free we've started Club ShowMeDo. The club will allow you access to some special videos we're making to pass on programming skills we consider important to the development and enjoyment of Free Open Source Software (FOSS).
The focus at the moment is on developing with the Python programming language, one of the backbones of the FOSS movement with a huge number of included and third-party libraries.
We welcome feedback and we want to hear your ideas.
Showmedo's development is fairly rapid and bugs will inevitably creep in. If you have any problems please drop us a line using the contact address below. Likewise, any suggestions for improvements to the site are gratefully received.
