| jelkner | Good day fkoikoi and tboimah! | 11:55 |
|---|---|---|
| fkoikoi | good morning jeff | 11:55 |
| *** jelkner_ has quit (Remote host closed the connection) | 11:56 | |
| fkoikoi | tboimah and I have a question for you | 11:56 |
| jelkner | i'll be right back | 11:56 |
| jelkner | i needed to change my login method | 11:56 |
| *** jelkner has quit (None) | 11:56 | |
| jelkner | there we go | 11:57 |
| jelkner | i'm back | 11:57 |
| jelkner | give me the question fkoikoi | 11:57 |
| jelkner | quick as you can fkoikoi | 11:58 |
| fkoikoi | why (-2 // 4) is given the answer to be -1 | 11:58 |
| jelkner | ah, good question | 11:58 |
| jelkner | first, there are two "division" operators in Python 3 | 11:59 |
| jelkner | \/ and \// | 11:59 |
| jelkner | hmm | 11:59 |
| jelkner | they are: / and // | 11:59 |
| jelkner | there we go | 11:59 |
| fkoikoi | why (2 % -4) is given the answer to be -2 | 11:59 |
| jelkner | so / takes to numeric values (int or float) and returns a float | 12:00 |
| jelkner | while // takes to int values and returns an int | 12:00 |
| jelkner | are you clear on why 15 // 6 is 2, for example? | 12:01 |
| fkoikoi | yeh | 12:01 |
| fkoikoi | yeah | 12:01 |
| jelkner | so 2 // 4 giving 0 makes sense, right? | 12:01 |
| fkoikoi | sure | 12:02 |
| dcammue | Good morning everyone | 12:02 |
| jelkner | great, so the question is, why the seemingly weird behavior of -2 // 4 giving -1, right? | 12:02 |
| fkoikoi | yes | 12:02 |
| jelkner | it's called "floor division" | 12:03 |
| jelkner | and i just did a quick web search and found this: | 12:03 |
| jelkner | https://www.pythontutorial.net/advanced-python/python-floor-division/ | 12:03 |
| jelkner | take a look at that and let me know if it clears things up for you | 12:04 |
| jelkner | you could also ask kevin more when he comes in 2 hours if you are still confused | 12:04 |
| jelkner | nice question! | 12:04 |
| jelkner | i haven't even thought about the % operator with negatives before | 12:05 |
| jelkner | so i need time to think about your 2nd question | 12:05 |
| jelkner | The % operator produces the "modulus" (remainder) | 12:06 |
| jelkner | so 2 % 4 is 2 because 4 divides 2 0 times with 2 remaining | 12:06 |
| jelkner | there is a cool python function called divmod that might help | 12:07 |
| *** dcammue has quit (Read error: Connection reset by peer) | 12:07 | |
| jelkner | try divmod(15, 6) | 12:07 |
| jelkner | what do you get? | 12:07 |
| jelkner | quickly please! | 12:08 |
| fkoikoi | 2, 3 | 12:08 |
| jelkner | great | 12:08 |
| jelkner | you actually got (2, 3), right? | 12:08 |
| fkoikoi | +1 | 12:08 |
| jelkner | what kind of thing is that? | 12:09 |
| jelkner | what datatype? | 12:09 |
| fkoikoi | integer | 12:09 |
| jelkner | nope | 12:09 |
| jelkner | it's a tuple | 12:09 |
| jelkner | and 2-tuple with 2 ints as elements | 12:09 |
| jelkner | the first element is the result of 15 // 6 | 12:10 |
| jelkner | and the second is the result of 15 % 6 | 12:10 |
| jelkner | the "div" and the "mod" | 12:10 |
| jelkner | hence the name, "divmod" | 12:10 |
| jelkner | i have to go | 12:10 |
| jelkner | but look into that more | 12:11 |
| jelkner | do what kevin advised you to do | 12:11 |
| jelkner | wonder, explore, play | 12:11 |
| jelkner | see you tomorrow morning | 12:11 |
| fkoikoi | sure | 12:11 |
| jelkner | i'm going to stay logged in so i can catch kevin when he arrives | 12:11 |
| jelkner | but i need to prepare for class now | 12:12 |
| jelkner | so i'll make myself "away" | 12:12 |
