python - TypeError: 'dict' object is not callable

Question

I'm trying to loop over elements of an input string, and get them from a dictionary. What am I doing wrong?

number_map = { 1: -3, 2: -2, 3: -1, 4: 1, 5: 2, 6: 3 }
input_str = raw_input("Enter something: ")
strikes = [number_map(int(x)) for x in input_str.split()]

---

strikes  = [number_map(int(x)) for x in input_str.split()]
TypeError: 'dict' object is not callable

Answer 1

The syntax for accessing a dict given a key is number_map[int(x)]. number_map(int(x)) would actually be a function call but since number_map is not a callable, an exception is raised.
