title: How to execute python from command prompt with parameters?
body: <p>I have created a python program, see below. It moves files to AWS S3. It it is expecting input. It works well with pycharm but when I call the python script from command prompt, it doesn't take the input value. Here is my code:</p>
  
  <hr>
  
  <pre><code>import os
  import sys
  import boto3
  from botocore.client import Config
  import configparser
  import re
  import os.path
  
  ## Initialize the Parameters
  def initconfig(input):
  
      config = configparser.ConfigParser()
      config.read_file(open( 'CONFIG_AIRBILLING.conf'))
      print('Code Name is :'+ input)
      global REMOTE_DIR,ACCESS_KEY_ID,ACCESS_SECRET_KEY,BUCKET_NAME,TARGET_DIR,FILENAME,SRC_DIR,data,File
      ACCESS_KEY_ID = config.get('ACCESS', 'ACCESS_KEY_ID')
      print('ACCESS_ID_IS:'+ ACCESS_KEY_ID)
      ACCESS_SECRET_KEY = config.get('ACCESS', 'ACCESS_SECRET_KEY')
      BUCKET_NAME = config.get('ACCESS', 'BUCKET_NAME')
      SRC_DIR = config.get(input, 'SRC_DIR')
      FILENAME = config.get(input, 'FILENAME')
      #LOC="C:\test\demo.txt"
      TARGET_DIR = config.get(input, 'TARGET_DIR')
      File='demo.txt'
      #data = open(File, 'rb') ## This is the filename, need to change it
  
  
  
  ## This function will make sure file exist in Source directory
  def readstatus():
      try:
          with open(File,'r') as f:
              f.closed
              result='True'
              movefiles(result)
      except (Exception,FileNotFoundError) as e:
          print('***Error:File Not Found or Accessible***')
          result='False*'
          raise e
  
  
  ## This function will move the files to AWS S3 bucket
  def movefiles(result):
      if result=='True':
          s3 = boto3.resource(
              's3',
              aws_access_key_id=ACCESS_KEY_ID,
              aws_secret_access_key=ACCESS_SECRET_KEY,
              config=Config(signature_version='s3v4')
          )
          s3.Bucket(BUCKET_NAME).put_object(Key=TARGET_DIR + '/' + File, Body=File)
          print('***File Moved***')
  
  
      print("Done")
  
  initconfig("ABC")
  readstatus()
  </code></pre>
  
  <hr>
  
  <p>The code above runs fine with pycharm because I can change the value of initconfig function value. But when I run this through command prompt, it doesn't take the parameter values I pass. Here is how I am passing the value, Please help me to fix this.</p>
