Python program that takes an integer and prints all numbers forward & backward, and prints sum of odd & even numbers.

Write the following functions: (5 points for each function)

  1. a function that takes an integer n and prints all numbers (1 to n inclusive) separated by a space.

  2. a function that takes an integer n and prints all numbers (n to 1 inclusive) in backward separated by a space.

  3. a function that takes an integer n and returns the sum of first n odd numbers (1 to n inclusive).

  4. a function that takes an integer n and returns the sum of first n even numbers (1 to n inclusive).

Write a program that reads a number form the keyboard. Call each of the above functions. Sample output with n = 10

Enter a number 10
print Numbers Forward: 1 2 3 4 5 6 7 8 9 10
print Numbers Backward: 10 9 8 7 6 5 4 3 2 1
sum of odd numbers: 25 sum of even numbers: 30

Write all the above 4 functions in a .py file.

n = int(input(“Enter a number “))

print(“Numbers Forward:”)

def forward(n):
     for x in range (1, n+1):
         print(x, end = ” “)
     return n

forward(n)

print()
print(“Numbers Backward:”)

def backward(n):
     for x in range (n, 1-1, -1):
         print(x, end = ” “)
     return n
backward(n)

print()
print(“Sum of Odd Numbers:”)

sum = 0
for x in range (1, n+1, 2):
     sum = sum + x

print(sum)

print(“Sum of Even Numbers:”)

sum = 0
for x in range (0, n+1, 2):
     sum = sum + x

print(sum)
