for loop - Python Text Document Translation Comparison -

fairly simple question. i'm trying create "translation comparison" program reads , compares 2 documents , returns every word isn't in other document. beginner class, i'm trying avoid using obscure internal methods, if means less efficient code. have far...

def translation_comparison():    import re    file1 = open("desktop/file1.txt","r")    file2 = open("desktop/file2.txt","r")    text1 = file1.read()    text2 = file2.read()    text1 = re.findall(r'\w+',text1)    text2 = re.findall(r'\w+',text2)    item in text2:        if item not in text1:            return item   

you might try

#######test data #file1.txt = test #file2.txt = test #results# #is  def translation_comparison():     open("file1.txt", 'r') f1:         f1 = f1.read().split()     open("file2.txt", 'r') f2:         f2 = f2.read().split()      word in f1:         if word not in f2:             print(word)   translation_comparison() 

also practice use

with open("file1.txt", 'r') f1:         f1 =f1.read().split() 

because when using open files close file when you're not using it. python pretty @ releasing , managing memory habit make sure release or call

file1.close() 

when done.
