Question

Create a Python file named num_sum.py that contains:

• The definition of two functions:
  • volume - accepts three parameters and returns the product of them, but displays nothing
  • sum_of_nums - accepts 1 or more numbers and returns their sum, but displays nothing
• A print function call that includes a call to volume, passing 2, 3, and 4
• A print function call that includes a call to sum_of_nums, passing 1, 2, 3, 4, and 5

Answer 1

# TEXT CODE

# Defining function volume

def volume(arg1, arg2, arg3):
  
# return the product of three arguments
return arg1*arg2*arg3

# Defining function sum
# The symbol * is used to take variable number of arguments, by convention, * is used with word args

def sum(*args):
  
# if zero arguments are passed simply return
if len(args) == 0:
return
  
#initialize varible res to 0, res stores sum of parameters
res = 0
  
# iterate through args
for arg in args:
  
# add arg to res, and update res
res = res + arg
  
  
# finally, return the res
return res

# driver code to check the above to functio with print function

# first call to print function with volume
print("Volume is:", volume(2, 3, 4))

# second call to print function with sum
print("Sum is:", sum(1, 2, 3, 4, 5))
