Reading line by line from a file in python

Tuesday, September 25, 2018

In order to extract some values from this file :

I need to read it line by line.
I tried to read line by line first but i don't know why it doesn't work.

I tried this :

#! /usr/bin/python
file = open('/home/results/err.txt')
for line in file.readline():
    print line

EDIT:

Problem: working but not showing this lines (this is the file)

Just the last line of them which is: (this is what is generated)

Answer

You need to iterate through the file rather than the line:

#! /usr/bin/python
file = open('/home/results/err.txt')
for line in file:
    print line

file.readline() only reads the first line. When you iterate over it, you are iterating over the characters in the line.
