Generally, it's easier to figure out what is going wrong if you give us the stacktrace. In this case:

>>> if x = y:
  File "<stdin>", line 1
    if x = y:
         ^
SyntaxError: invalid syntax

Note that the ^ is pointing to where in the source the error is. x = y is an assignment, assigning the value of y to x. Assignments are not allowed as a test. I'm guessing you wanted to compare the two values to see if they were equal, in that case you need to say

  if x == y:

note the equality operator is spelled ==. A better error message would probably have been helpful...
