写入文件

Posted 2020-08-22 Bio-Liu

问题：编写一个程序，提示用户输入其名字；用户作出响应后，将其名字写入到文件guest.txt中。

过程：

　name.py　

1 filename = ‘guest.txt‘
2 with open(filename,‘w‘) as file_object:
3     print ("Please enter your name:")
4     file_object.write(input())

 

cmd窗口下运行：python name.py 机会首先打印出

Please enter your name:，然后输入一个名字，enter结束，此时输入的名字就被写入到了guest.txt

在进一步：用户输入其名字后，在屏幕上打印一句问候语，并记录添加到文件guest_book.tx

1 filename = ‘guess_book.txt‘
2 with open(filename,‘a‘) as file_object:
3     while True:
4         name = input("Please enter your name:")
5         file_object.write(name + "!  Welcome come to Beijing\n")
6         if name == ‘haha‘:
7             break
