    infraweight? xD

    name = "Peter"
    height_m = 2
    weight_kg = 65

    bmi = weight_kg / (height_m ** 2)
    if bmi < 18.5:
    print(name , "is infraweight")
    else:
    if bmi < 25:
    print(name ,"has a normal weight" )
    else:
    print(name , "is overweight")
    print("Your bmi is" , bmi)

    —– result —–

    Peter is infraweight
    Your bmi is 16.25

    dont judge me, i just started learning it 1 hour ago xD

    This guy is good, not a boring teacher at all. Learning python after a couple of years of always putting it off. Wanna see what I can do with it in a linux environment for systems, network and server administration.

    Also if you guys don't want the hassle of installing programs to get an IDE going, go to https://repl.it/, you have an IDE via your browser. 🙂

    I was in the process of learning UI/UX and thought I might pick up basic Python just so I can understand one programming language. I signed up to a TAFE course teaching Python (an Australian technical college network). Instead of teaching how to use Python, they make it super hard by talking about programming, but in the first place I have no clue about programming. (The course must have been written by an academic) Goodness me. I feel as if I'd never be able to learn Python. Luckily I found this video, after watching this video, the course material started to make sense. Why can't normal classes teach like CSDOJO, well done mate!!

    I have a question, I was trying to put underweight as well in the code but I can't seem to do it because it contradicts to bmi < 25. The underweight is about bmi < 18.5, since they're both the same, Python is only recognizing bmi < 25. Is there a way I can put both of it ?

    Using Else Statement in python programming
    https://youtu.be/TYrisKb6hrM
    Really such a good idea

    y = np.array(list(map(lambda x:1 if x=="positive"

    x:-1 elif x=="negative":
    else 0 , y)))

    where is the problem do you know ? where I have a column for y containing 3 classes positive, negative and neutral , I want to give value for positive= 1 , negative =-1 and neutral =0 then …how to fix it?

    could you please do the same for java?

  41. Phoebe Rayy August 1, 2020 at 8:40 am - Reply

    7:56 why does the second line get printed? Shouldn't only the first line get printed. I am under the impression an if else statement essentially means if this is true then do this otherwise do this..

    Idk why sometimes teachers teach us the complicated way
