Facing Problem while opening a file through command prompt

[vlearner]

Hi Everyone,

Here is the code that I have written for reading a file through command prompt.

from sys import argv

 script, filename = argv

 txt = open(filename)

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

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

 txt_again = open(file_again)

 print(txt_again.read())

but while executing this program I am facing this error

Error:
 txt = open(file.txt)
AttributeError: 'str' object has no attribute 'txt'

please guide me through this problem
