Python Programming Tutorial - 28 - You are the only Exception

[davidboskovic]

i cant believe we are 28 tutorials in and its the first time we had the user input something

"The user was an idiot." - Bucky Roberts

[seanbrown]

Yep your cool. Bucky! You are literally my favorite programming teacher ever.

[fixxxer]

Dude, you helped me with Android, now you are helping me with python :) god or whatever you believe in, bless you!

[MIO_sh]

Serious question: I'm pretty curious on whether the fucking NullPointerException that always waste my a lot of time exist in Python as well?

[revuutube]

Past 3 tutorials: build a web crawler to rival simple Google mostly building off script that another code wrote as a module

this tutorial: oh wait I forgot to teach them what try does lol

Still love ya bucky

[arock]

I had to use "NameError" instead of "ValueError", I'm guessing because I'm using Python 2.7.13.

Thanks for great tutorial, Bucky.

I dont know why but I like the channel display picture so much..!!!

[Zwerggoldhamster]

I like to ask the user for their first input before I enter the while loop. Then for example I try to get the integer, and if I have a ValueError, I can already ask for an input in the exception, then repeat the loop and try to convert to a an int, etc.

The title tells me Bucky likes Paramoe.

[xXPumpkinPvPTutsXx]

you are the one that made me wanted to program more in python because you make it sound so interesting so i linked you in my channel (OmeglaWaffles101) and i subscribed

If ''break" leads us to go outside loop, how come "finally complete " can run?

[inspades]

For those using these videos. There is one way to catch all errors and still know whats going on:
"except Exception as e: print(e)"

Original page:

[bogite]

while True:
try:
number = int(input("what's your fav number?"))
print("Wow, ", number, " Is my favorite number too!")
break
except ValueError:
print("Please enter a valid number.")

[bipul]

can you please upload a video on the topic - using debugger in pycharm....
i kind of don't know how to use a debugger

[TerryDeSimone]

I have a question, running the source from this video.. I was surprised when the return value came back as a "FLOAT", when you specifically "casted" the input value as a "INT".. 3 entered / 6.0 returned..
are INT's & FLOATS interchangeable in Python 3.6? (having a PHP background, they are not the same).. but i just seen it with my own eyes.. lol

[pillowdokusayer]

but if you remove the (int) it would fix it, you could type words and numbers

[MrSKYFOUR]

Thanks for helping! I wonderd why my code did not work: had to change to an integer.
Anyway awsome  tutorial as always!

[MainManPhillis]

Could someone explain the purpose of the "while True:" before the try statement.  It seems like we would never exit the loop because we never explicitly return false. I'm coming from java so its also weird that there is no object attached with "True".

i am new to python coding,
can you tell me how to raise custom exception in python?
