ValueError: too many values to unpack ( expected 2)

Question

This is error it shows everytime I run
from sys import argv
script, input_file = argv

Answer 1

from sys import argv

script, input_file = argv

def print_all(f):
print(f.read())

def rewind(f):
f.seek(0)

def print_a_line(line_count, f):
print(line_count, f.readline())

current_file = open(input_file)

print("First let's print the whole file:\n")

print_all(current_file)

print("Now let's rewind, kind of like a tape.")

rewind(current_file)

print("Let's print three lines:")

current_line = 1
print_a_line(current_line, current_file)

current_line = current_line + 1
print_a_line(current_line, current_file)

current_line = current_line + 1
print_a_line(current_line, current_file)

Answer 2

Please share your complete code here. To get a clear picture of what happens, a short snippet is not very helpful. Thanks!

Answer 3

The code you showed here, is meant to be started from the os command line e.g.:
python test1file.txt

To get the code run i have slightly modified the first few lines. What you have to do is to create a txt file with at least 4 lines. The name of this file has to be used in the code, and the file should be in the same directory:
