[issue44438] argparser documentation error

[Raymond Hettinger]

Raymond Hettinger  added the comment:

If you read the text afterwards, you'll see that raising a TypeError was the 
intended purpose of this example.  Just afterward, it shows how to use *type* 
to make the code correct.

[issue44438] argparser documentation error

[Arman Sargsyan]

New submission from Arman Sargsyan :

URL - https://docs.python.org/3/howto/argparse.html

The following code will return a type error:

import argparse
parser = argparse.ArgumentParser()
parser.add_argument("square", help="display a square of a given number")
args = parser.parse_args()
print(args.square**2)

This should be changed to:

import argparse
parser = argparse.ArgumentParser()
parser.add_argument("square", help="display a square of a given number")
args = parser.parse_args()
print(int(args.square)**2)
