How to convert upper case letters to lower case

Question

I have a script which reads the input and then lists it, however, I want it to convert upper case letters to lower case, how can I do that?

this is what I got

for words in text.readlines(): 

sentence = [w.strip(',.') for w in line.split() if w.strip(',.')] 

list.append(sentence)

Answer 1

You can use str.lower(), it converts all cased characters to lowercase.

Answer 2

Try using the code given below:

w.strip(',.').lower()
