List comprehension with if statement
if-statement, list-comprehension, python
Solution
You got the order wrong. The `if` should be after the `for` (unless it is in an `if-else` ternary operator)
[y for y in a if y not in b]
This would work however:
[y if y not in b else other_value for y in a]
Problem
I want to compare 2 iterables and print the items which appear in both iterables. ``` >>> a = ('q', 'r') >>> b = ('q') # Iterate over a. If y not in b, print y. # I want to see ['r'] printed. >>> print([ y if y not in b for y in a]) ^ ``` But it gives me a invalid syntax error where the `^` has been placed. What is wrong about this lamba function?
