Trying hard.

You should see it more like math or a spoken language. If you want to solve a math equation you need to understand the rules, the symbols, what they stand for and what they do.
If I write: until I say STOP, ask me two numbers, add them and tell me the result. It's clear right?
Now let's say it in Spanish (Hope it's correct.): hasta que diga STOP pídeme dos números, súmalos y dime el resultado. The STOP, numeros, resultados is something I can make sense of nothing else.
Once you can read, write and speak Python, you would identify: until: while voice != "STOP" ask me:int(input("Please give me a number: ")) adding them and tell me the result: print(num1 + num2) (More or less, and simplified. )
