in Python, how can i write from a text file with each word being a different element? -

i need use file in format:

product1,33,84 product2,18.50,72 product3,22,96 

and need write elements list in format:

['product1', '33', '84', 'product2', '18.50', '72', 'product1', '22', '96'] 

however when writing code, closest was:

[['product1', '33', '84'], ['product2', '18.50', '72'], ['product1', '22', '96']] 

using code:

for line in productlist.readlines():     line = line.replace(",", " ")     line = line.strip("\n")     line = line.split(" ")     products.append(line) 

how can either write element or merge these nested lists?

you're there. want products.extend(line) instead of append. extend method adds each element of iterable (in case, line) list (products), instead of adding item list @ once, append does. final code (condensed little) looks this:

for line in productlist.readlines():     line = line.replace(",", " ").strip("\n").split(" ")     products.extend(line)
