Note that you have no variable called 'file'.
So this line doesn't make sense.

This bit will work if you omit the line above and
fix the indentation. (and remove the 'e' from strip()

This should be outside the loop, you don't want
to close the file after every line.

Finally, there is another way to do this which
is considered 'better'/more Pythonic:

with open("C:\coderoot\python3\level1\inputfile.txt", 'r') as f:
     for line in f:
         print(line.strip())

Notice with this construct the closing of the file is
handled for you.

When posting questions always include the full error text.
Although apparently cryptic it actually contains a lot of
useful detail which saves us from making guesses.
