Is there a way to loop through a list and use them individually as an index?

Question

I have two lists, what I'd like to know how to do is use the values in the first list as indexes in the second. Then I can append each iteration to a new list.

    out_pass = ['w', 'Q', '4', 'z', 'e', 'h', '8', '9', '!', '@', '3', 'A']
    Lines = [2, 4, 5, 8, 11, 6, 0, 10, 1, 3, 7, 9]
    fin = 0
    fin_pass = []
    while fin < Len(lines)
      fin_pass.append(out_pass[2]) <-- Then 4, 5, 8 etc...
      fin += 1
      

Answer 1

Here's a version of your code that I think does what you want, keeping the structure pretty much the same:

out_pass = ['w', 'Q', '4', 'z', 'e', 'h', '8', '9', '!', '@', '3', 'A']
lines = [2, 4, 5, 8, 11, 6, 0, 10, 1, 3, 7, 9]
fin_pass = []
for line in lines:
    fin_pass.append(out_pass[line])
print(fin_pass)

Result:

['4', 'e', 'h', '!', 'A', '8', 'w', '3', 'Q', 'z', '9', '@']

Note: I renamed a few things, but mostly please note that I changed Lines to lines. You should capitalize Type names but variable names should always be lowercase. This is just a convention, but it's one that is quite universal, and not following it will make your code more difficult for others to read and understand.
