Python: Searching Values in a list

I have the following set-up:

stuff = ['apple', 'I like apples today', 'orange', 'oranges and apples guys']

What I want to do: I want to search each value in a list to see if the word "orange" is contained anywhere within that lists index value.

In other words, my expected output is this:

orange
oranges and apples guys

What I am currently getting back is nothing.

Here is what I am currently doing:

for x in range(0, len(stuff), 1):

     if 'orange' in stuff[x] == True:
          print('testing to see if this works')

I am not successful with this, any suggestions?

Edit #1:

I tried searching for the contains syntax to use with the re module, but did not return anything useful.

Edit #2:

What about for cases like this:

stuff = ['crabapple']

'apple' in stuff

False

The word "apple" does exist, it's just part of another word. In this case, I'd like to return that as well.

Use list comprehension

print ([x for x in stuff if "orange" in x])

The find method of strings returns the index of the substring, or -1 if not found:

for s in stuff:
    if s.find('orange') != -1:
        print(s)

use this:

for x in range(0, len(stuff), 1):
    if ('orange' in stuff[x])== True:
        print('testing to see if this works')

for your code, python will judge 'stuff[x] == True' (and it will be False) then judge 'orange in False' so it will always be False.

The way you use in is not correct, you should remove ==True, or python will treat it as 'orange' in a binary list.

for x in stuff:
    if 'orange' in x:
        print('testing to see if this works\n')
        print(x)

testing to see if this works

orange
testing to see if this works

oranges and apples guys
