本文实例讲述了Python按行读取文件的实现方法。分享给大家供大家参考，具体如下：
小文件：
|
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
|
#coding=utf-8#author: walker#date: 2013-12-30#function: 按行读取小文件all_lines = []try: file = open('txt.txt', 'r') all_lines = file.readlines()except IOError as err: print('File error: ' + str(err))finally: if 'file' in locals(): file.close()for line in all_lines: print(line) |
大文件：
|
1
2
3
4
5
6
7
8
9
10
11
12
13
|
#coding=utf-8#author: walker#date: 2013-12-30#function: 按行读取大文件try: file = open('txt.txt', 'r') for line in file: print(line)except IOError as err: print('File error: ' + str(err))finally: if 'file' in locals(): file.close() |
希望本文所述对大家Python程序设计有所帮助。
