How to make a function accept runtime arguments

Question

I want to define a function such that I want it to accept command line arguments

below is my code

def tc1(resloc):
    from uiautomator import Device;
    'Do some activity'
    with open(resloc, 'a') as text_file:
            text_file.write('TC1 PASSED \n')
            text_file.close()
    else:
        with open(resloc, 'a') as text_file:
            text_file.write('TC1 FAILED \n')
            text_file.close()    

if __name__ == '__main__':
    tc1("C:\\<pathtoautomation>\\Results\results.txt")

Now when I execute the same using command line from python it continues to refer to the path mentioned here tc1("C:\\<pathtoautomation>\\Results\results.txt") and doesn't consider what I pass in the runtime from the command line

\Scripts>python.exe trail.py C:\\<pathtoautomationresults>\\Results\results.txt

Did you take a look at [`sys.argv`](https://docs.python.org/2/library/sys.html#sys.argv)? — bereal, Aug 05 '15 at 11:29

You want `tc1(sys.argv[1])` or possibly a loop over `sys.argv[1:]`. — tripleee, Aug 05 '15 at 11:31

What you are looking is sys.argv

The list of command line arguments passed to a Python script. argv[0] is the script name (it is operating system dependent whether this is a full pathname or not). If the command was executed using the -c command line option to the interpreter, argv[0] is set to the string '-c'. If no script name was passed to the Python interpreter, argv[0] is the empty string.

To loop over the standard input, or the list of files given on the command line, see the fileinput module.

You use it like:

import sys

def main(argv):
    # do something with argv.


if __name__ == "__main__":
   main(sys.argv[1:])  # the argv[0] is the current filename.

and call it using

python yourfile.py yourargsgohere

You need to use sys.argv to get command line parameters.

in your code it could look like this:

import sys
...  # other stuff

if __name__ == '__main__':
    tc1(sys.argv[1])

There are many tutorials out there that help you use sys.argv
