Python can count the number of lines in a file, do you believe it? Whether you believe it or not, I do. Let's take a look at how python counts the number of lines in a file. The code is very simple. I also made comments and it is very simple to implement. . .

#_*_coding:utf_8
#引入sys和系统os模块
import sys 
import os 
&#39;&#39;&#39;
计算某一个文件的行数
&#39;&#39;&#39;
def countFileLines(filename): 
    count = 0
    try: 
        handle = open(filename, &#39;r&#39;) 
        #循环文件句柄
for eachline in handle:
            #累加
            count += 1
    #异常捕获
    except IOError, e: 
        print &#39;file open error&#39;, e
    return count 
    
print countFileLines(&#39;/home/pythontab/tmp/a.php&#39;)
