Multiplying and dividing numbers in Python is really straightforward. It returns an integer or a float value depending on the multiplication result. . Then, when you encounter a failed test: Test.assert_equals(multiply(3, 5), 15) You will see the following output: 3 5 8 should equal 15. Here is the link: codewars.com. def multiply(a, b=10): return a*b multiply(12) # 120 multiply(2, 3) # 6 multiply(b=9) # error: None*9 is not valid In this function, if user does not give the second parameter b, it assumes it to be 10, but providing the first parameter is necessary. Codewars. I'm having it print the return value of the function when supplied with 2 and 3. If you've ever multiplied or divided numbers in other coding languages, you'll find the process for doing so in Python is really similar, if not pretty much exactly the same. The official Python docs suggest using math.fmod() over the Python modulo operator when working with float values because of the way math.fmod() calculates the result of the modulo operation. The operator module also defines tools for generalized attribute and item lookups. If you've ever multiplied or divided numbers in other coding languages, you'll find the process for doing so in Python is really similar, if not pretty much exactly the same. @JomoPipi the simplest analogy would be: having a maze with several routes through it, what is easier: find any route, or find any route which goes through one mandatory point?.
