python access global variable

globvar = 0

def set_globvar_to_one():
    global globvar    # Needed to modify global copy of globvar
    globvar = 1

def print_globvar():
    print(globvar)     # No need for global declaration to read value of globvar

set_globvar_to_one()
print_globvar()       # Prints 1

python edit global variable in function

globalvar = "flower"

def editglobalvar():
	global globalvar # accesses the "globalvar" variable, so when we change it
    # it won't assign the new value to a local variable,
    # not changing the value of the global variable
    
    globalvar = "good" # assigning new value
    
print(globalvar) # outputs "flower"
# if we didnt use the "global" keyword in the function, it would print out 
# "flower"

#To do this, at the start of your function/method write "global" and then the name of the variable.
#Example:
myVariable = 1

def myFunction():
  global myVariable
