Write a program to have following functions:

Q. Write a program to have following functions :

(i) 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.

(ii)  A function that takes two char arguments and returns True if both the arguments are equal otherwise False.

Test both these functions by giving appropriate function call statements.

Answer :-

(i)

def cube( a = 2 ) :
    print( "Cube of ", a ,"="  , a ** 3 )

num = input("Enter a number (For empty press Enter ) :")

if num == "" :
    cube()
else :
    cube( int (num) )

Output

Enter a number (For empty press Enter ) :9
Cube of  9 = 729
>>>

Enter a number (For empty press Enter ) :
Cube of  2 = 8
>>>

(ii)

def chr(char1,char2) :
    if char1 == char2 :
        return "True"
    else:
        return"False "

char1 = input("Enter a Char 1 : ")
char2 = input("Enter a Char 2 : ")
print(chr(char1,char2))

Output :-

Enter a Char 1 : Path
Enter a Char 2 : Walla
False
>>> 

Enter a Char 1 : Path
Enter a Char 2 : Path
True
>>>
