If I need to, can I use more than one type conversion at once, like
Absolutely! You can nest as many conversions as you want without confusing yourself. Sometimes, for example, you may take input from the user that you need for a calculation. Input is a string that must be converted to a number. If you wanted to make it complicated for some reason, you could do:
user_input = float(int(user_input))
But know that you can do this if you ever need to and can’t avoid it!
