Printing current and previous number sum in a range(10)
Current Number 0 Previous Number  0  Sum:  0
Current Number 1 Previous Number  0  Sum:  1
Current Number 2 Previous Number  1  Sum:  3
Current Number 3 Previous Number  2  Sum:  5
Current Number 4 Previous Number  3  Sum:  7
Current Number 5 Previous Number  4  Sum:  9
Current Number 6 Previous Number  5  Sum:  11
Current Number 7 Previous Number  6  Sum:  13

Hint:

Create a variable called previous_num and assign it to 0
Iterate the first 10 numbers one by one using for loop and range() function
Next, display the current number (i), previous number, and the addition of both numbers in each iteration of the loop. At last, change the value previous number to current number ( previous_num = i).

Solution:

print("Printing current and previous number and their sum in a range(10)")
previous_num = 0

# loop from 1 to 10
for i in range(1, 11):
    x_sum = previous_num + i
    print("Current Number", i, "Previous Number ", previous_num, " Sum: ", previous_num + i)
    # modify previous number
    # set it to the current number
    previous_num = i
