Practical Data Wrangling

Returning values from a function

In addition to passing in information when a function is executed, it is also possible to retain information afterward using the return statement. A return statement is simply the word, return, followed by the value to be returned, and is written at the end of the code block:

def myFunction():    <some code>    return <return value>    

The return value is captured outside of the function by assigning the function call to a variable. In the following example, I've modified the code slightly to print the reaction to the weather outside of the function:

def reactToTheWeather(isSunny):    if isSunny:        return "Nice Weather!"    else:        return "No sun today!"reaction1 = reactToTheWeather(True)print(reaction1)reaction2 = reactToTheWeather(True) ...
