Answer 1

Your code was poorly formatted and indented, which is intolerable in python.
Correct code:

a = input()
x = int(input())
y = int(input())

def sum(a,b):
p = (a+b)
print(p)

def substract(a,b):
p = (a-b)
print(p)

def division(a,b):
if b != 0:
p = (a/b)
print(p)

def multiply(a,b):
p = (a*b)
print(p)

if a == "sum":
sum(x,y)
elif a == "substract":
substract(x,y)
elif a == "multiply":
multiply(x,y)
elif a == "division":
division(x,y)
else:
print("not available")

Answer 2

You must first defining function and then call it, like this:

def sum(a,b):
p=(a+b)
print (p)
def substract(a,b):
p=(a-b)
print (p)
def division (a,b):
if b!=0:
p= (a/b)
print (p)

def multiply(a,b):
p=(a*b)
print (p)

a= input ()
x=int(input ())
y= int(input ())
if a =="sum":
sum(x,y)
elif a=="substract":
substract(x,y)
elif a=="multiply":
multiply(x,y)
elif a=="division":
division(x,y)
else:
print ("not available")

thank you all.
