Why is IDLE's Shell color coding keywords in user response to input(prompt)?

I'm working on a Python 3 program that takes input from the user via the Python Shell. For some reason when I enter the information into the shell (once the input asks for info...), it's coloring keywords & functions with specific colors.

For example, if I type in "John is blue". It will color the word "is" as a keyword (Which it technically is but this is string input).

I haven't been able to bring up anything relevant on google so I'm bring the question here. Thanks.

Here is the code that runs the input.

    if __name__ == '__main__':

            global string
            string = str(input('Enter info: '))
            string = bytes(string.encode("utf-8"))
            c = cont.key_gen_01()
            c.func_01()



            run_a = obf_01()
            run_a.func_02()
           #run_a.func_03()
            run_a.func_04()

            run_a.func_05(string)

Solution

  • Colorizing in IDLE editor and Shell windows is done by the IDLE syntax colorizer. In Shell, it also colors console prompts ('>>> '), internal IDLE errors (now extremely rare), user code tracebacks, and user code output. (Colors can all be customized on the Highlights tab of the Settings dialog.) So the colorizer should not be turned off between code entries.

    Unless your program is requesting entry of python code, I consider colorizing input() responses to be a minor bug. But it is not obvious how to tell the colorizer to ignore them. To a display, input() prompts are normal output. Besides which, responses can be entered before the prompt. Try the following with or without hitting ENTER before the prompt.

    import time; time.sleep(5); s = input('what??? '); print(s)

    The above also works in python, but at least in Windows Console, I don't see the entry until the prompt is displayed.
