Thanks to the lack of parenthesis and curly braces, the code is always much clearer and more readable than C or C++ code! Example: C++ vs Python if (x>0) { std::cout << "x is positive." << std::endl; } if x>0: print("x is positive.") #Python4president

Function modulo is easy. For example 14 modulo 3. We must find number, which is smaller than 14 (<14), can be divided ( /) and it will be rational number (1, 2, 3... Not numbers like 3,123). It's 12 (12/3=4). Then we just subtract 14 and 12 (14-12). It's 2.

In the short code below, I declared an array of five elements. But I'm getting confused on how to use it in a while loop. My main question is , if the user inputs a userchoice1 value that is less than 1, I want the code to keep looping until the user inputs a number that is not less than 1. But I don't know if the 7th line (userchoice1 [x]++) shows the right way to loop it.

Isn't this just a reoccurring function called from within itself until a particular set of conditions are met? I don't know it just seems like shorthand to me. Like a do-while loop. I am sure it could be used for more than just factorials.

I can not figure this out. Write a program using an array to prompt for 10 grades and add them all up and divide by 10 to find the average. If a user inputs a negative number, add up all the numbers that are not negative and divide it by the amount of numbers that are not negative. Using two functions other than main.
