Looks like you have a few steps that are missing. What is your goal with this game?
I'm not terribly familiar with Python, what is the member type for the questions? Are you accepting user inputs as strings only, and then comparing the input string to the check string? Appears that is the case from what you have shown above.
For Q1, what happens if I type in " 3898747", where there is a space at the beginning of my input, would that cause my answer to be determined as incorrect?
If I answer Q1 wrong, do you have a check to ask again until I answer it correctly, or do you just skip to the next question, what if I want to quit the program before all questions are asked, do you have a way to exit the program in the middle of reading inputs from the user?
For the first question "Do you want to play a game?", what happens if I answer "No"? The capitalized 'N' will likely cause the next line to execute, even though the quit method is intended to execute. You should use a method to assign to a boolean value, or for all characters to be rewritten in a lower or upper case and then checked by the tool.
For Q2, what happens if I write the answer in Celcius or Kelvin? What happens if I am missing the 'F' part? What happens if I type in "10001 F", would that cause it to fail the question? May consider taking the input string, converting to an float or double, and then checking unit cases and have the user's answer be correct if they are within 1% or something. Alternatively, you can indicate in the question statement that the answer must be in fahrenheit, but you'll still probably want to give some bounds to a correct answer (should 9999 really be a failing answer?).
What about adding up together the number of answers the user got correct and returning that back to the user at the end of the method?
