[Learning] 3 hours for one simple exercise

This is the entire code resolved. I will leave the answer here. Sorry for being late!

def calc(n):
    i = 1
    total = 0
    if (1 <= n <= 100):
        for i in range(1, n+1, 4):
            aux = i**2
            total = aux + total
    else:
        total = -1
    return total;
    

# Program
num=int(input("Input number "))

sum = calc (num)

if (sum==-1):
    print("The number is not in range")
else:
    print("The total of the calc is: ", sum)
