For calculating the sum I used a while-loop. This one is nested in an if-else statement, so that the program can tell the user when we confused the lower with the upper bound.
This is my code:
print("I will calculate the sum of numbers in a range you select.")
numLow = numLow1 = int(input("What is the lower bound? "))
numUp = int(input("What is the upper bound? "))
x = int(numLow)
if numLow <= numUp :
while numLow != numUp :
numLow = numLow + 1
x = x + numLow
print("The sum of numbers in the range between", numLow1,"and",numUp,"is",x)
else:
print("You didn't type in the numbers in the right order.")
print(numCom,"was the right number!")
print("You needed",attempt,"attempts.")
