Python-check what position it is in a list

Question

list1 = ['physics', 'chemistry', "dog", "cat","dog"];

I want it to say if I typed in an input dog it will tell me dog is the forth one and sixth one.

I have swapped the dupe target to a more suited question. – Bhargav Rao Feb 01 '16 at 18:27 — Bhargav Rao, Feb 01 '16 at 18:27

Use list comprehensions:

list1 = ['physics', 'chemistry', "dog", "cat","dog"]

string = input()
res = [i for i, el in enumerate(list1) if el == string]

print(res)

Output:

[2, 4]
