Finding string in list item

[deanhystad]

This always prints "HIT" because the expression "501" or "502" in node always returns "501". Remember that "a or b" returns a if a is true-ey, else it returns b. In your expression a = "501" and b = ("502" in node). "501" is not an empty string, so it is true-ey.

if "501" or ("502" in node):
    print("HIT")
