Creating Sublists from a “List”

Question

I have a list in a file, looks like this

c4a24534,2434b375,e750c718, .... 

I have split at \",\" and brought the below list.

x         


        

Answer 1

Assuming this is a contents of input.txt file:

c4a24534,2434b375,e750c718

Use zip() for splitting into two lists:

with open('input.txt') as f:
    i, q = zip(*((x[:4], x[4:]) for line in f for x in line.split(',')))

print i
print q

Prints:

('c4a2', '2434', 'e750')
('4534', 'b375', 'c718')

These are tuples, if you need to make lists from them, call list() on each:

print list(i)
print list(q)
