How do I run Python script using arguments in windows command line

This is my python hello.py script:

def hello(a,b):
    print "hello and that's your sum:"
    sum=a+b
    print sum
    import sys

if __name__ == "__main__":
    hello(sys.argv[2])

The problem is that it can't be run from the windows command line prompt, I used this command:

C:\Python27>hello 1 1

But it didn't work unfortunately, may somebody please help?


Python Command Line Arguments – Real Python, Windows Build Tools: This includes the Windows command line Execute the script argv.py above with a list of arbitrary arguments as follows:. You can easily pass command line arguments to a Python script. In this tutorial, we will help you to read the command line arguments in a Python script. Below is the sample Python script, which reads the command line arguments and print details. Create a sample script like script.py and copy below content.


To execute your program from the command line, you have to call the python interpreter, like this :

C:\Python27>python hello.py 1 1

If you code resides in another directory, you will have to set the python binary path in your PATH environment variable, to be able to run it, too. You can find detailed instructions here.

Python - Command Line Arguments, Python - Command Line Arguments - Python provides a getopt module that Now run above script as follows − options − This is the string of option letters that the script wants to recognize, with options that require an argument should be� len(sys.argv) is the number of command-line arguments. Here sys.argv[0] is the program ie. script name. Example. Consider the following script test.py − #!/usr/bin/python import sys print 'Number of arguments:', len(sys.argv), 'arguments.' print 'Argument List:', str(sys.argv) Now run above script as follows − $ python test.py arg1 arg2 arg3


Command Line Arguments in Python, In this tutorial, we're diving into Command Line Arguments in Python. or -- followed by a word, like --help; Windows: / followed by either a letter, or word, like /help python arguments-count.py The script is called with 0 arguments $ python � Much like the previous example, save the below lines of code in an editor as command_line.py and to run the code type python3 command_line.py 10 where 10 is the command line argument. import sys num = sys.argv[1] for i in range(int(num)): print (i) What if you do not provide any command line argument?


Your indentation is broken. This should fix it:

import sys

def hello(a,b):
    print 'hello and thats your sum:'
    sum=a+b
    print sum

if __name__ == "__main__":
    hello(sys.argv[1], sys.argv[2])

Obviously, if you put the if __name__ statement inside the function, it will only ever be evaluated if you run that function. The problem is: the point of said statement is to run the function in the first place.

(Tutorial) How to Run Python Scripts, Learn how you can run a PYTHON script from the COMMAND-LINE, and also how you can provide command line ARGUMENTS to your script. Also, the way Python scripts are run in Windows and Unix operating systems� Python allows you direct access to the command line arguments via an array called sys.argv - you'll need to import sys first. The first element in this array is always the program name, but the second and third will be the numbers you pass in i.e. sys.argv and sys.argv. For a more complete example:


import sys

def hello(a, b):
    print  'hello and that\'s your sum: {0}'.format(a + b)

if __name__ == '__main__':
    hello(int(sys.argv[1]), int(sys.argv[2]))

3. Using Python on Windows — Python 3.3.7 documentation, Unlike most Unix systems and services, Windows does not require Thus, you can also execute your scripts with command line options, and any additional command-line arguments specified will be sent directly to Python. I may not have explained what I wanted to do very well. I do not want to modify the 'program.py' file I originally mentioned. I want to create a new script that runs the 'program.py' script multiple times on a list of arguments, using one argument each time. – Chris Oct 15 '10 at 3:24


The Easy Guide to Python Command Line Arguments, One of the strengths of Python is that it comes with the ability to do just To pass the command line argument to the Python script, execute it by� Python scripts can be run using Python command over a command line interface. Make sure you specify the path to the script or have the same working directory. To execute your Python script (python_script.py) open command line and write python3 python_script.py Replace python3 with python if your Python version is Python2.x.


How to Run a Python Script via a File or the Shell, Run a Python script under Windows with the Command Prompt. Windows users must pass the path of the program as an argument to the� The sys module implements the command line arguments in a simple list structure named sys.argv. Each list element represents a single argument. The first item in the list, sys.argv, is the name of the Python script. The rest of the list elements, sys.argv to sys.argv [n], are the command line arguments 2 through n.


Running Python Programs From Command-Line, Use the values of command-line arguments in a program. Handle We can run this script from within the IPython Notebook like this: $ python�
