I'm new to files in Python and I'm having trouble removing the 'n' and the word None in my output console. Here's my code:

def function(inputFile, wordFile):
 input = open(inputFile, 'r')
 words = open(wordFile, 'r')

 wordList = 

 for line in words:
 wordList.append(line.split(','))

 print(wordList)
 words.close()

##call function
result = function("file1.txt","file2.txt")
print(result)
print()

my file2.txt/wordFile/words looks like this:

hello,world

123,456

This is the output I get:

['hello', 'worldn']

['123', '456n']

None

I know there's a lot going on but how do I remove the 'n' and None?

To get rid of whitespace characters you can use strip:

wordList.append(line.strip().split(','))

Also your function does not not return anything, so result = function("file1.txt","file2.txt") will assign nothing to result also called None in python. To have it return something, use return at the end of the function:

return wordlist

It is also possible to return mulitple variables:

return var1, var2, ...

You can get them by

a, b, ... = function(..)
