学习python第n'''天——我在看笨办法学python(读取文件)

这是读取文件的内容

This is stuff I typed into a file.
It is really cool stuff.
Lots and lots of fun to have in here.

这是代码

from sys import argv

script, filename = argv

print(f" Here 's your file { filename }:")
txt=open(filename).read()
print(txt)

print(" Type the filename again:")
file_name = input("> ")

txt_again = open(file_name)

print(txt_again.read( ))

这是运行结果

PS C:\Users\HH\lpthw> python ex4.py ex4_sample.txt
Here 's your file ex4_sample.txt:
This is stuff I typed into a file.
It is really cool stuff.
Lots and lots of fun to have in here.

Type the filename again:
> ex4_sample.txt
This is stuff I typed into a file.
It is really cool stuff.
Lots and lots of fun to have in here.
