Hello, I was doing some computation and sometimes we have to get quotient and remainder of a value, for instance quotient = value // divider remainder = value % divider So I was thinking maybe we could introduce a new operator to get both like quotient, remainder = value %% divider but I don’t ...

What is the result of this code: print(6 // 0.4) I thought the answer is 15.0 but I am getting 14.0. Any explanation for this answer I will appreciate. More on discuss.python.org

There's a function called divmod that does both, and if you use that a few times, you'll get a feel for the difference. For example, let's say you have a quantity of money, and you want to make change. cents = 93 quarters, cents = divmod(cents, 25) dimes, cents = divmod(cents, 10) nickels, cents = divmod(cents, 5) At each step, we take as many chunks as we can (that's the div), then we keep any leftovers (that's the mod) More on reddit.com

Think back to old school 4th-ish grade division, before you knew that decimals and fractions were a thing. What's 47 divided by 4, in that world? Long division it out: 11 --- 4|47 -4 -- 7 -4 -- 3 What you get is "11 remainder 3". Which makes sense because 4*11 is 44, and 47-44 is the remainder, 3. What divmod does is give you both the 11 and the 3 in one operation. so if you do: quotient, remainder = divmod(47, 4) print(quotient, remainder) # 11, 3 So that's what it's doing. Now, why are doing it? Well suppose you want to know how many minutes and seconds are in 257 seconds. You know 60 seconds is one minute. You could do division and get that 257/60 is 4.283333 minutes, and that'd be correct. Or you could do the long division thing: 4 ---- 60|257 -240 --- 17 This is telling you that 60 can fit into 257 4 times, with 17 left over. The quotient is 4. The remainder is 17. So 257 can be divided into 4 groups of 60 seconds - which is exactly 4 minutes - leaving 17 seconds left over. Which means that 257 is 4 minutes and 17 seconds. Likewise, if there were more than 60 minutes, you could convert minutes to hours and minutes the same way. division like this without doing decimal stuff is called "integer division", and getting the remainder by itself is often called the "modulus" operator. You can do this in two separate steps by doing quotient = 257 // 60 remainder = 257 % 60 But if you need both, use divmod - it's more efficient. I get the feeling that most people halfway forget about long division with remainders after a couple years, but it turns out integer quotients and remainders are insanely useful for a huge variety of programming tasks.
