In Python, how do I read a file line-by-line into a list? 35 answers

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.

file.readline() already reads one line. Iterating over that line gives you the individual characters.

Instead, use:

for line in file:
    …

尝试这个：

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