Explanation / Answer

#python code

#part 1
sum = 0
i = 1
while i <= 100:
   sum = sum + i
   i =i + 1
print "Sum of all positive numbers from 1 to 100 is ",sum
#output: Sum of all positive numbers from 1 to 100 is 5050

#part 2
startingValue = int(raw_input("Enter the starting value: "))
endingValue = int(raw_input("Enter the ending value: "))

sum = 0
while startingValue <= endingValue:
   sum = sum + startingValue
   startingValue = startingValue + 1
print "Sum of all positive numberss form",startingValue,"to",endingValue,"is",sum

'''
output:

Enter the starting value: 23
Enter the ending value: 56
Sum of all positive numberss form 57 to 56 is 1343
