'Return' keyword returns only one element from a loop?

Question

I have a simple function to read the csv file and extracts the first coloum from it:

import csv 

def pass_username():
    with open(\'test.csv\', \'r\') as          


        

Answer 1

When you call return, it autimtically exits out of the function, so it doesn't process anything after it reaches the return statement.

You might want to append the result to a list, then return the list.

In your case, you might even want to use a list comprehension, so instead of the for loop, use this:

return [row[0] for row in spamreader]
