I was making a programming language in Python 3.6 when I stumbled across something odd. With the following code, I get an error, with some interesting output.

import sys

import tkinter as tk

import datetime



class _Viper:

    def __init__(self):

        pass

    def error(self, err, title="ERROR"):

        root = tk.Tk()

        root.title(title)

        root["bg"] = "#d56916"

        label = tk.Label(root, text=err)

        labelt = tk.Label(root, text=str(datetime.datetime.now()))

        label.config(bg="#e67a27")

        labelt.config(bg="#d56916")

        label.grid()

        labelt.grid()

        root.mainloop()

    def grabdata(self, line):

        raw = line.split("(")

        raw[1] = raw[1][:-1]

        print(type(raw[1]))

        raw[1] = raw[1].split()

        #raw[1] = raw[1].split('"')

        return {

            "keyword" : raw[0],

            "params"  : raw[1].split()

        }



Viper = _Viper() #For PyLint

"""

try:

    sys.argv[1]

    execute = True

except:

    execute = False

    Viper.error("Error `Viper.FileNotProvidedError` @ interpreter.py. Do not directly run this file. Run it with `Viper0.0.0a C:\path\to\file`, or associate viper to Viper0.0.0a.bat.")

"""



sys.argv.append("C:\viper\interpreter\testie.vi")

execute = True



if execute:

    extension = str(sys.argv[1][-2]+sys.argv[1][-1])

    if extension.upper() == "VI":

        with open("C:\viper\interpreter\testie.vi", "r") as src:

            lines = src.readlines()

        for line in lines:

            Viper.grabdata(line)

    else:

        Viper.error("Error `Viper.ExtensionNotViperError` @ interpreter.py. Please run this with a file with the "vi" extension.")

After running this, I get this error.

Are you seeing what I'm seeing? <class 'str'> is the class of raw[1]. Nothing there. But when I refer to it after, it says that it's a list!

Can someone tell me what's going on here?

EDIT

I forgot to add the viper file.

setvar("hmm", "No")

EDIT 2

I'm going to explain my issue. It's treating a string as a list.

The line after you print the type:

 raw[1] = raw[1].split()

This turns it into a list. When you call raw[1] later with "params" : raw[1].split(), it is not a string anymore, but a list. So this means raw[1] is being split twice. If you are intending to return the parameters in raw[1] as a list, you could just remove the line raw[1] = raw[1].split().
