List index find by given string

I have a list and I have a given string. The list looks like the following:

["hello, whats up?", "my name is...", "goodbye"]

I want to find the index in the list of where the given string is, for example:

I tried to use list_name.index(given_string) but it says "whats" is not in the list.

That is because whats is not really present in the list. The list actually has "hello, whats up?". So if you set the value of given_string to be like - given_string = "hello, whats up?", then you will get 0 as index. The index method just compares the values, in this case entire string. It does not check for values within the string.

Edit 1: This is how I would do it:

list = ["hello, whats up?", "my name is...", "goodbye"]
for index, string in enumerate(list):
     if 'whats' in string:
             print index

You could do something like the follwoing:

l = ["hello, whats up?", "my name is...", "goodbye"]
sub_s = "name"
indx = [i for i, s in enumerate(l) if sub_s in s]
print(indx) # [1]

This is more robust in the case where you have more then 1 index
