可执行python文件sys不接受'（'字符

Question

I am trying to write a python file that takes command line input and performs some actions. The input will consist of az, [, ], ( and ). I made the following program just to check that I could keep going:

#!/usr/bin/env python
import sys

print str(sys.argv)

I did chmod +x program and tried calling ./program qwerty (abc) [hi] and it returned:

-bash: syntax error near unexpected token `('

Is there any way of changing the program so that it accepted parentheses in arguments?

Note: I have also tried placing square brackets before parentheses and it returns the same error.

Answer 1

There's nothing the script can do about shell syntax when invoking the script. The shell parses the command line first. You have to escape or quote characters that have special meaning in the shell (which includes most punctuation characters):

./program qwerty \(abc\) '[hi]'
