AttributeError - Namespace-Objekt hat kein Attribut Benutzername

Question

Hallo bin neu zu Python und versuchte, unterhalb Skript und Attribut Fehler zu bekommen.

#!/usr/bin/python 
import json

import argparse 

    try: 
    import requests 
    except ImportError: 
    print "Please install the python-requests module." 
    sys.exit(-1)

    location += "?per_page=10000" 
    r = requests.get(location, auth=(devincuser, password),verify=False) 
    return r.json() 

    def main():

und bekommen Schlag Fehler Traceback (jüngste Aufforderung zuletzt): File "./pyth.py", Linie 136, in main() File "./pyth.py", Zeile 44 in Haupt , wenn nicht (args.username und args.password): Attribute: 'Namespace' Objekt kein Attribut 'username' hat

Answer 1

Sie haben ein username Argument in Ihrem ArgumentParser nicht definiert. Sie haben etwas definiert, das devincuser heißt, wollten Sie das stattdessen verwenden?
