Answer 1

This should do it.

nums = []
with open("yourfile.txt","r") as f:
     for line in f:
         nums.append(line)

Now, each line is stored together in an index of the array. If you want to access the values one by one, you can just iterate and split:

for i in nums:
    print(i.split(",")[0] + " " + i.split(",")[1])

To access them together, just go through the indexed of the array.
