如何在Mac上对Python文件进行编程以使用终端选项

Question

I am building a python file and instead of asking for user input I want it to get the information on the execution command. For example, I want to be able to type in

python code.py -i "information"

Instead of having to execute code.py and then tell the code "information". How do I do this? PS I am using MacOS mojave as the tags indicate. Thanks.

Answer 1

You can utilize sys.argv in your Python script to read command-line arguments and store them in a list of strings that you can then parse, as follows:

from __future__ import print_function
import sys
print(sys.argv)

Then, from the terminal:

> python code.py -i "foo bar"
['code.py', '-i', 'foo bar']

Answer 2

You can use python's argparse module to use command line arguments. https://docs.python.org/3/library/argparse.html
