这篇文章主要介绍了关于Python 实现在文件中的每一行添加一个逗号,有着一定的参考价值,现在分享给大家,有需要的朋友可以参考一下

步骤1:读取每行(每行的类型是str)

步骤2:对每行列表化

步骤3:弹出每行的/n两个字符

步骤4:追加,/n三个字符

代码实现如下:

#import os
From_file=open('D:\\python\\A\\tianqi.txt')
f=open('niuniu1.txt','w')
count=0
huancun=[]
for each_line in From_file:
 #print(type(each_line)) each_line 是字符类型
 Delstr=list(each_line)
 Delstr.pop() #弹出n
 Delstr.pop() #弹出\
 Delstr.append(',\n')
 huancun="".join(Delstr)
 print(huancun)
 f.writelines(huancun)
 count+=1
 huancun=[]
f.close()
From_file.close()
print('文件中总共有:%d行'%count)
