    print(checkio("mega,cloud,two,website,final", "window,penguin,literature,network,fun,cloud,final,sausage"))

Maybe a stupid question, but after a cycle of comparing two strings, "two" appears in the result variable, although it is not in the 2nd list

The problem is that you use the "in"(substring) operator instead of the (equal)"==" operator. So the "two" it finds is the "two" which is inside of the word "neTWOrk".

Yes... "two" is in "window,penguin,literature,network,fun,cloud,final,sausage"

The sequence of 3 characters: t, w, o is present in line2, thus it is in the result.

You should compare sets by splitting line2.

def checkio(line1: str, line2: str) -> str:
  result = ''

  for word in line1.split(','):
    if word in line2.split(','):
        result += word + ','

  result = ','.join(sorted(result.split(',')))
  return result[1:]

The word two is in the second string (in network).

It's better and easier to split both strings into sets and then return the intersection of these in a join.

def checkio(line1: str, line2: str) -> str:
    s1 = set(line1.split(','))
    s2 = set(line2.split(','))
    return ','.join(s1 & s2)


if __name__ == "__main__":
    print("Example:")
    print(checkio(
        "mega,cloud,two,website,final", 
        "window,penguin,literature,network,fun,cloud,final,sausage"))

You must split line2 with "," and make a list.Your problem is that you search in a string and "two" is in "network". I just add a line in your function.

'''

def checkio(line1: str, line2: str) -> str:
    #just add following line
    line2_list=line2.split(",")
    result = ''
    for word in line1.split(','):
        if word in line2_list:
            result += word + ','
    result = ','.join(sorted(result.split(',')))
    return result[1:]


if __name__ == "__main__":
    print("Example:")
    print(checkio("mega,cloud,two,website,final", 
    "window,penguin,literature,network,fun,cloud,final,sausage"))
