PYTHON

Python scope

# Variables have different levels of scope. Some include global and local scopes.

myVar = 5 # This is a global variable. It is not in any functions.

def myFunc():
  # global myVar
  
  myVar = 10 # This is a local variable

myFunc() # Runs myFunc
print(myVar) # Prints 5. The local variable in myFunc did not change the value of myVar.
# If you added 'global myVar' in myFunc, myVar would be changed to 10.

python variable scope

a = 5

def f1():
  a = 2
  print(a)
  
print(a)   # Will print 5
f1()       # Will print 2

how does scope work in python

a = 5
b = 3

def f1():
  a = 2
  print(a)
  print(b)
  
print(a)   # Will print 5
f1()       # Will print 2 and 3

Python Scope

def myfunc():
  x = 200
  print(x)

myfunc() #works
#print(x) does not work
#as a rule, you can use a variable more "outside" than you but you cannot use a variable more "inside".
