python习题15

 1 # 从python的内置模块中引入模组
 2 from sys import argv
 3
 4 # 解包，获取文件名
 5 script, filename = argv
 6
 7 #返回某文件对象
 8 txt = open(filename)
 9
10 #打印这句话，嵌入文件名
11 print(f"Here‘s your file {filename}:")
12 #读取文件内容并且打印
13 print(txt.read())
14
15 print("Type the filename again:")
16 # 把用户输入提示符号设置为>，赋值给file_again
17 file1 = input(">")
18
19 #打开文件
20 txt_again = open(file1)
21
22 #打开文件并且打印
23 print(txt_again.read())

用input写这个脚本

 1 filename = input("输入文件名字：")
 2
 3 txt = open(filename)
 4
 5 print(f"Here‘s your file {filename}:")
 6 print(txt.read())
 7
 8 print("Type the filename again:")
 9 file_again = input(">>>")
10 txt_again = open(file_again)
11
12 print(txt_again.read())

在提示符下用open打开一个文件
