[Solved] Using readlines to read data file and sum columns

[Laplace12]

I'm not a regex expert, but the following code might help you

import re

# line = " 0           2           0      -15000           0"
line = "50           2           2      -14950           3"
Values = re.split(r"\s?([+\-]?\d+)\s+([+\-]?\d+)\s+([+\-]?\d+)\s+([+\-]?\d+)\s+([+\-]?\d+)", line)
print(f"1rst value : {Values[1]}")
print(f"2nd value : {Values[2]}")
print(f"3rd value : {Values[3]}")
print(f"4th value : {Values[4]}")
print(f"5th value : {Values[5]}")

Got the issue resolved by using np.loadtxt and data[-1:1,1] type commands. Thanks for your help!
