Part Three: Conclusion

Congratulations on completing Part 3. You have learned a lot and on your way to becoming a programmer with Python 3.

Here is a summary of what was learned in Part Three:

·        We learned about functions in Python 3. We have the built-in functions like print() and input() but we can also have user-defined functions.

·        To create a user-defined function, we use the def keyword. We then specify all our lines of code for what the function is to perform under that.

·        We learned about using arguments in our functions. We could also specify default parameters for our functions. We can also use docstrings so as to have documentation on what the function does.

·        We wrote a better code to improve our calculator. We were able to achieve a better calculator app using functions.
