Question

In this example how to call "function func_call_from_terminal" from python terminal when the code running?

example: The name of the python script is "TEST.py"

def func_call_from_terminal():
 # in this function I need to print I_Value ... 
 # where this function must call from terminal during...
 # the running script TEST.py.
if __name__ == "__main__":
 I_Value = 1
 Flag = True
 while Flag :
 I_Value += 1
 if I_Value == 1e9
 Flag = False

• Barmar: What do you mean by the "python terminal"? If you're running a script, you need to put the function call in the script. Do you mean you want to interrupt the script while it's running?
• Barmar: Take a look at the KeyboardInterrupt exception.
• F.Rahmouni: My bad, I mean from terminal, no I won't interrupt the script I just need to call the function from terminal for example : >python func_call_from_terminal.py
• Barmar: You could make the script check sys.argv and call the function depending on the arguments.
• Barmar: What value of I?

Answer 1

Just open terminal and use this command

python -c 'import TEST; TEST.func_call_from_terminal()'
