Changes

In order to use functions from other scripts, you are required to either issue the import command in your ipython3 shell environment, or use the '''import ''' command within your Python script itself.<br><br>We can demonstrate the use of re-using functions from another script by simply '''issuing statements from the ipython shell by calling to call a function that is related to from your lab3a.py Python script'''. But care MUST be taken to first use the import command to load in the function declarations from your Python script to your ipython shell environment first.<br><br>

:Functions can pass-up receive '''arguments''' - data to be used for processing. In this section, you will learn how to define functions that accept arguments and learn how to perform function calls that pass up call functions with arguments for processing (such as mathematical operations or testing conditions, which is useful for error-checking).

</source>When passing arguments up to functions, you MUST contain put data such as '''strings''', '''numbers''', or '''variable names''' within '''brackets''' immediately following the function name.<br><br>'''NOTE:''' If a function accepts arguments, then those '''arguments rguments must be defined''' declared (using variable names) when the function is declared.. Those declared variable names are then used within the function for processing. Also, when you call a function with arguments, the number of arguments passed up to the function must correspond (match) the number of arguments that were specified in the function declaration.<br><br>
