I want to retrieve data starting from 2nd row assigned to the corresponding column automatic with the other file. How can i do that?

Ex:

Spresence=['0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0',...]

Thank you so much!

Answer 1

import re
Spresence = []
with open('yourFile.txt') as FL:
    for line in FL.readlines()[1:]:
        m = re.match("\S+\s+\S+\s+\S+\s+(.*)", line)
        if m:
            Spresence+=re.split('\s+',m.group(1))

output

>>>Spresence
['0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '1', '0', '0', '1', '0', '0', '1', '0', '0', '1', '0', '0', '1', '0', '0', '1', '0', '0', '1', '0', '0', '1', '0', '0', '1', '0', '0', '1', '0', '0', '1', '0', '0', '1', '0', '0', '1', '0', '0', '1', '0', '0', '2', '1', '1', '1', '0', '0', '3', '1', '1', '1', '0', '0', '4', '1', '1', '1', '0', '1', '2', '1', '1', '1', '0', '0']

Answer 2

A bit hacky but it works:

import os
file = open("file.txt", 'r')
spresence = []
for line in file.readlines():
        splitLine = line.split(" ")
        if len(splitLine) < 5:
                continue
        if splitLine[4] == "SPresence":
                continue
        spresence.append(splitLine[4])
print spresence

Opens the file, creates an array, for each line in the file it splits the line per each space and then grabs the 5th element in the line which would be the SPresence column. It takes that element and adds it to the sprescence array and prints at the end
