Python implements line of code counting tool

We often want to count the number of lines of code in a project, but if we want to have a more complete statistical function, it may not be that simple. Today we will take a look at how to use python to implement a line of code counting tool.

Idea: First get all the files, then count the number of lines of code in each file, and finally add the number of lines.

Function implemented:

Count the number of lines in each file;

Count the total number of lines;

Statistics on running time;

Supports specifying statistical file types and excludes file types that do not want to be counted;

Recursively counts the number of lines of files in folders including sub-files;

Excludes blank lines;

# coding=utf-8
import os
import time
basedir = '/root/script'
filelists = []
# 指定想要统计的文件类型
whitelist = ['php', 'py']
#遍历文件, 递归遍历文件夹中的所有
def getFile(basedir):
    global filelists
    for parent,dirnames,filenames in os.walk(basedir):
        #for dirname in dirnames:
        #    getFile(os.path.join(parent,dirname)) #递归
        for filename in filenames:
            ext = filename.split('.')[-1]
            #只统计指定的文件类型，略过一些log和cache文件
            if ext in whitelist:
                filelists.append(os.path.join(parent,filename))
#统计一个文件的行数
def countLine(fname):
    count = 0
    for file_line in open(fname).xreadlines():
        if file_line != '' and file_line != '\n': #过滤掉空行
            count += 1
    print fname + '----' , count
    return count
if __name__ == '__main__' :
    startTime = time.clock()
    getFile(basedir)
    totalline = 0
    for filelist in filelists:
        totalline = totalline + countLine(filelist)
    print 'total lines:',totalline
    print 'Done! Cost Time: %0.2f second' % (time.clock() - startTime)

Result:

[root@pythontab script]# python countCodeLine.py 
/root/script/test/gametest.php---- 16
/root/script/smtp.php---- 284
/root/script/gametest.php---- 16
/root/script/countCodeLine.py---- 33
/root/script/sendmail.php---- 17
/root/script/test/gametest.php---- 16
total lines: 382
Done! Cost Time: 0.00 second
[root@pythontab script]#

will only count php and python files, which is very convenient.

In fact, you can also make improvements based on this, such as excluding comment lines, etc.
