Define a function cumsum(num). The function returns the sum of all positive integers smaller or equal to num.Examplecumsum(4) -> 1+2+3+4 = 10cumsum(5.5) -> 1+2+3+4+5 = 15Hintint() converts a float type value into an interger.
Question
Define a function cumsum(num). The function returns the sum of all positive integers smaller or equal to num.Examplecumsum(4) -> 1+2+3+4 = 10cumsum(5.5) -> 1+2+3+4+5 = 15Hintint() converts a float type value into an interger.
Solution
Sure, here is a Python function that implements the cumsum function as described:
def cumsum(num):
# Convert the number to an integer
num = int(num)
# Initialize the sum to 0
sum = 0
# Loop over all numbers from 1 to num (inclusive)
for i in range(1, num + 1):
# Add the current number to the sum
sum += i
# Return the sum
return sum
You can use this function like this:
print(cumsum(4)) # Outputs: 10
print(cumsum(5.5)) # Outputs: 15
This function works by first converting the input number to an integer. Then it initializes a variable sum to 0. It then loops over all numbers from 1 to num (inclusive), adding each number to sum. Finally, it returns sum.
