写入文件

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
