    View Code

    如果我们要修改其中一些文字,可以运用以下:

    1 y = open('yesterday','r')
    2 y_new = open('yesterday_new','w')
    3 tihuan = input('输入要替换的替换:')
    4 tihuan_new = input('输入要替换的替换:')
    5 
    6 for i in y:
    7     if tihuan in i:
    8         i = i.replace(tihuan,tihuan_new)
    9     y_new.write(i)

    找出yesterday文件,如果要修改什么,可以input输入:,比如要修改其中的

    1 So many wild pleasures lay in store for me
    2 有那么多肆意的快乐等我享受

    把我修改成Tuskasa:

    可以

    tihuan = input('输入要替换的替换:')
    输入:有那么多肆意的快乐等我享受
    再输入:有那么多肆意的快乐等Tuskasa享受
    就会创建一个新的文件并修改(注意是创建一个新的文件,这样我们就可以保存原文件,避免丢失)

    或者可以另外定义:
     1 import sys
     2 find_str = sys.argv[1]
     3 replace_str = sys.argv[2]
     4 
     5 y = open('yesterday','r')
     6 y_new = open('yesterday_new','w')
     7 
     8 for i in y:
     9     if find_str in i:
    10         i = i.replace(find_str,replace_str)
    11     y_new.write(i)

    注意一定要记得close()文件
