在python中如何计算特定参数后传递的arguments的数量？

Question

in python how to count the number of arguments passed after a specific argument?

Explanation:

[user]$ command1 -h 192.168.1.1 -p 8888 -t 50 -u -c ...etc  main.py arg1 arg2 arg3

here when using sys.argv in main.py the number of arguments is 12 ( or more, it may differ every time )

i want to count only arguments after main.py so only: arg1 arg2 arg3 which is "3".

Any solution?

Thanks.

Answer 1

You could get the index of main.py within the sys.argv , and then slice accordingly:

main_index = sys.argv.index('main.py')
arguments_after_main = sys.argv[main_index:] # Should contain only arg1 arg2 arg3
