python program prints a variable then says its not defined.why? (closed)

Question

print ("hello world")


x = input ("we are starting the count from >> ")
x = int  (x)  #makes the input string of x to int


y = input ("we are ending our count at >> ")
y = int (y)  #makes the input strint of y to int


def deleting_extars():
    l = ( (x*(x-1))/ 2)
    l = int (l)
    pass

deleting_extars()

def make_the_others_count():
     p = ((y*(y-1))/2)     p = int (p)
     print (p)
     pass
make_the_others_count()

def final_func():
    print (p-l)


final_func()

now if i run the program u can see it prints "p"
in the terminal the output

$python python.py
hello world
we are starting the count from >> 4
we are ending our count at >> 55
1485
Traceback (most recent call last):
  File "/home/moula/x/python.py", line 30, in <module>
    final_func()
  File "/home/moula/x/python.py", line 27, in final_func
    print (p-l)
NameError: name 'p' is not defined

we can see it prints "p" but then it says p is not defined
"p" is inside a function so is "l" but "l" works fine why "p" does not?

Answer 1

the variable p is in a local area of the function where it was declared, you can declare it outside or return it in a variable and use that variable
