Not all data returned from sys.argv

[ecdhyne]

In my password lookup pgm sys.argv only returns the pgms file location. How do I get the selected input?

1 2 3 4 5 6 7 8 9 10 11

#! python 3 # pw.py - password lookup pgm PASSWORDS = {'hotmail': 'ECDaug#2019',              'isimail': 'ECDaug#2019',              'tdadmin': 'ecdisi04'}   import sys, pyperclip print (sys.argv) print ('This is the name of the script: '), sys.argv[0] print ('Number of arguments: '), len(sys.argv) print ('The arguments are: ') , str(sys.argv)

example (file tmp.py)

1 2 3 4 5 6 7

import sys   if __name__ == '__main__':     print(len(sys.argv))     print(sys.argv[0])     print(sys.argv[1])     print(sys.argv[2])

start with:

python3 tmp.py first second

Output:
3
tmp.py
first
second

@ecdhyne
line 8 should print list with file name and all CLI arguments

The problem with lines 9-11 is the closing place where you put closing parenthesis of print function. As is now each line is just at 2-element tuple (so a valid code)
let's look at line 9
print ('This is the name of the script: '), sys.argv[0]
it execute the print function (everything before the comma)
print ('This is the name of the script: ')
print function returns None
here the line in interactive mode

1 2 3 4 5 6 7 8 9 10

>>> import sys >>> print ('This is the name of the script: '), sys.argv[0] This is the name of the script: (None, '') >>> print ('Number of arguments: '), len(sys.argv) Number of arguments: (None, 1) >>> print ('The arguments are: ') , str(sys.argv) The arguments are: (None, "['']")

lines 9-11 should be

1 2 3

print ('This is the name of the script: ', sys.argv[0]) print ('Number of arguments: ', len(sys.argv)) print ('The arguments are: ', str(sys.argv))

or better use string formatting, e.g. str.format() or f-strings
