Nested list comprehension printed invalid

[azz]

Input

l = [i for j in k if j%2 == 0 if j*2 < 20 for i in j if i%2==0]

Output

l = [i for j in k if j % 2 == 0 j * 2 < 20 for i in j if i % 2 == 0]

Expected

l = [i for j in k if j % 2 == 0 if j * 2 < 20 for i in j if i % 2 == 0]
#                               ^^

I'm not sure if that's even valid code, but it caused AST_COMPARE to fail on python_expressions/expressions.py.

I'm not sure if that's even valid code

It’s equivalent to:

l = []

for j in k:
    if j % 2 == 0 and j * 2 < 20:
        for i in j:
            if i % 2 == 0:
                l.apppend(i)
