Question

I have a text file which include some numbers and words as shown below.

How to read first column and second column?

After reading the file, I need to get an average value of the first column.

33512 test1
3312  test2
551   test3
33    test4
5     test5

Answer 1

vals = []

with open('filename.txt', 'r') as f:
    for line in f:
        vals.append(line.split()[0:2])

numbers = [val[0] for val in vals]
avg = sum(numbers) / len(numbers)
