Python Map List of Strings to Integer List

Question

Let\'s say I have a list

l = [\'michael\',\'michael\',\'alice\',\'carter\']

I want to map it to the following:

k = [1,1,2,3         


        

Answer 1

If I'm reading you correctly, you want to take a list of characters and convert them to integers, with a being 1, b being 2, etc.

l = ['a','b','a','c']
k = [ord(x.upper()) - 64 for x in l]

Threw the upper() in there so it doesn't matter whether they're upper case or lower.
