----BEGIN CLASS---- [14:10] #startclass [14:11] ! [14:11] next [14:11] how do we control the 1st number? [14:11] skat-sd, good question [14:11] so range actually take three parameters [14:12] first parameter is the number form which you want to initiate the range [14:12] second number is the number till which that range should count excluding the number [14:13] and third is the step [14:13] sayan, rtnpro fhackdroid we had documentation https://ircbot.readthedocs.io/en/latest/ [14:13] add: fhackdroid [14:13] masters [14:13] .masters [14:13] kushal: Error: "masters" is not a valid command. [14:13] ohh, like this: for i in range(1,10): print(i). Got it [14:13] skat-sd, yes [14:13] thanks, fhackdroid [14:14] skarpy, not only that but you can try something like range(1, 10, 2) [14:14] fhackdroid - in 2s? [14:14] jasonbraganza, yes [14:14] got it [14:14] try it :) [14:14] Fhackdroid: ok [14:15] hope you guys are clear with range ? [14:15] yes ? [14:15] Yes. [14:15] yes [14:15] yes [14:15] Yes [14:15] yes [14:15] yes [14:15] cool so lets do a simple problem ?

[14:20] if the number is multiple of 3 [14:20] it should print scooby instead of 3 [14:20] fhackdroid, we were using azure notebooks for Python sessions, should we use that?

[14:56] got it :) problem exists between keyboard and chair [14:56] nobody knows what this problem is called ? [14:56] cool let me give you something to search for [14:56] this problem is called the fizz buzz problem [14:57] this problem is called the fizz buzz problem [14:57] Oooh ! I solved the same on Hackerearth [14:58] yeah fhackdroid got it [14:58] :) dont know why they give such a typical name [14:58] Fizz Buzz Test [14:59] https://stackoverflow.com/questions/9461446/c-programming-the-fizzbuzz-program [14:59] fhackdroid - is that what we just did? [14:59] It's working for & too instead of and. Is this correct or not? [15:00] anuGupta, & is bitwise and not logical and [15:00] Yup but it gave the correct answer so asked [15:00] ikshitij, yes [15:00] any questions till now ? [15:00] jasonbraganza, yes that is what you did :) [15:00] i always thought FizzBuzz was something complicated :P [15:01] ! [15:01] jasonbraganza, well you uncomplicated the complicated [15:01] next [15:01] unrelated to the clas question [15:01] next [15:01] how legal is it to use the youtube-dl module to download music lists? asking because samridhia is using the module as an example and I’m worried for her. should she change her blog post? [15:01] which distributed services you know about/use/heard ? e.g. SVN is distributed [15:01] It's working for & too instead of and. Is this correct or not? [15:02] Why is it giving correct output [15:02] pie3, class is going on [15:02] anuGupta, You should figure it out why it is working. What is the result of 1&0? [15:02] jasonbraganza, AFAIK it is not legal [15:02] how to jump into class [15:03] jasonbraganza, are there any legal issues with modules too? [15:03] Oh yes thanks ashwanig [15:03] jasonbraganza, she should read more about copyright [15:03] samridhia: legal issues are with dowloading content without permission i think [15:03] anuGupta, https://stackoverflow.com/questions/22646463/difference-between-and-boolean-vs-bitwise-in-python-why-difference-i [15:03] jasonbraganza, samridhia, let's discuss it after class [15:04] samridhia, not the module, but *what* you download I think [15:04] Ok fhackdroid [15:04] bhavin192, ok i will now read everything about copyright. [15:04] hope that answers your question [15:05] jasonbraganza: downloading content from YouTube is illegal, doesn't matter you use x module or y module or you are FBI officer :) [15:05] okay guys so do you guys know about the data structure called list in python ?
