Question

Write a program using a function that takes a number
as argument and calculates cube for it. The function
does not return a value. If there is no value passed to
the function in function call, the function should
calculate cube of 2. Python

Answer 1

PYTHON PROGRAM FOR CUBE CALCULATION OF A NUMBER.

Language used : Python Programming

Program :

def cubecalculation(num=2): #default value = 2

   cube=num**3                     #else, just write print(num**3)

   print(cube)

num=int(input())

cubecalculation(num)           #calling with parameter

cubecalculation()                 #calling without parameter

Input :

30

Output :

27000              #Output for the function call with 30 as its parameter

8                       #Output for the function call wih no parameter

Explanation :

• ** is an power operation. the left side operand will be the number on which the power operation is performed, while the right operand will be the power value.

• If you use var=value in function definition's parameter passage, it will be act as a default value. Means, if the function is called without any parameter, the default value will be considered as a parameter. Always remember that default values should always be placed on the last arguments of the function.

• Now, after writing a function definition, take an integer input from the user and store it in a value.

• If you pass that value as a parameter during function calling, the function definition takes it and performs cube operation on it. Here, as we take 30 as input, passed it; the operation goes as :

        30**3 = 27000

• If you send no parameter during the call, 2 will be automatically taken as a parameter, as we arranged it as a default value, and the function performs cube operation on it, as :

        2**3 = 8

Answer 2

Answer:

(i)

#definition of the program

def cube(n=2):

 cube=n^3

 print("Cube of",n,"is=",cube)

#main program

num=input("Enter any number (Press enter to input nothing):")

if num=="":

 cube()

else:

 cube(int(num))

(ii)

#definition of the function

def compare(val1,val2):

 if val1==val2:

   return True

 else:

   return False

#main program

v1=input("Enter any character:")

v2=input("Enter another character:")

print("Both are equal:",compare(v1,v2))
