Python Programming Tutorial - 15 - Variable Scope

[dangkhoa]

1:31AM in the morning good freaking job Bucky

[baleia]

here a useful code to understand variable scope

a = 1738

def corn():
print(a)

def fudge():
a = 3817
print(a)

corn()
fudge()
corn()

fudge changes the valeu of 'a' but corn can't see it

[HamidNourashraf]

a can be defined after function definition and before function call as well.

def corn()
print(a)

a = 10
corn()


output: 10

When i get a job as a professional programmer, will I be able to call my functions/methods things like tuna and beef? Imagine trying to go through the source code of something written like that :)

[rileypurcell]

I thought they are called global and local variables

[tvpcoder]

The variable can also be used anywhere else outside the function/s (i.e below), not only if it's above it.

[BobRoffey]

When a variable is created inside a function is becomes a local variable to that function, you can still use that variable name outside the function as it is then global to the program;

a = 1234

def corn():
a = 7823
print(a)

def fudge():
print(a)

corn()
fudge()

[harsh_jain]

If you want a variable that is defined inside a function to be used by other functions than write global before the variable name.
Ex. Global a =272

What is the : symbol used for? I've always wondered.

[naqibjunaidy]

bucky I believed there are two python tutorials in ur videos... one that is not HD and another is HD. and I cant find the hd one is ur playlist...
and If I searched, keep on ending up at the non-hd version of python tutorials

[sgangoly]

When I try to run the same code as Bucky nothing gets printed in my run console pls help.
It just says: Process finished with exit code 0

How does the scope work if you are importing the functions from another file?

Say I have a in file 1 and try to call and modify it from file 2, what would that look like?

[prajnaneerukonda]

your explanation is awesome. Can you help me what IDE you're using to execute it

[leonardotornesello]

idk if it is the version, but i, whit python 3.6.1, i can pick variables from outside a function.

[flow]

function are mean they will not allow to use their variable

[nikhilb]

When do we need to use singlequotes(' ') and doublequotes(" ")
