CHALLENGES
Prior to completing a challenge, insert a COMMENT with the appropriate number.
1) Get an integer from the keyboard, and print all the factors of that number. Example, using the number 24:
Factors of 24 >>> 1 2 3 4 6 8 12 24
2) A "cool number" is a number that has a remainder of 1 when divided by 3, 4, 5, and 6. Get an integer n from the keyboard and write the code to determine how many cool numbers exist from 1 to n. Use concatenation when printing the answer (shown for n of 5000).
There are 84 cool numbers up to 5000
3) Copy your code from the challenge above, then modify it to use a while loop instead of a for loop.
5) A "perfect number" is a number that equals the sum of its divisors (not including the number itself). For example, 6 is a perfect number (its divisors are 1, 2, and 3 >>> 1 + 2 + 3 == 6). Get an integer from the keyboard and write the code to determine if it is a perfect number.
6) Copy your code from the challenge above, then modify it to use a do-while loop instead of a for loop.

WILL GIVE BRAINLY IF RIGHT When should a double equal sign (==) be used?
to set the value of a decimal variable
to set the value of a float variable
to check whether two pieces of data are actually equal
to indicate greater than or less than
The double equal sign (==) should be used to check whether two pieces of data are actually equal. It should not be used to set the value of a variable. Instead, a single equal sign (=) should be used to set the value of a variable. The double equal sign is used in programming languages to perform a comparison between two values and determine if they are equal. For example, you might use the double equal sign to check if a user's input matches a certain value, or to compare the value of one variable to another.

What allows a programmer to write code quickly and efficiently for an action that must be repeated?.
Answer:
iteration - loops
Explanation:
Write a program that computes an integer's checksum. To compute the checksum, break the integer into its constituent digits and, working from right to left, doubling every second digit. If the product results in a number with two digits, treat those two digits independently. Then, sum all the digits for the final checksum. For example, 1496 has a checksum of 21. We compute this by first breaking 1496 into constituents and doubling the ever second digit => 6, 18, 4, 2. Then, the individual digits are summed as 6 + (1 + 8) + 4 + 2 = 21.
Answer:
def checksum(num):
total = 0
count = 0
while num > 0:
digit = num % 10
count += 1
if count % 2 == 0:
digit *= 2
while digit > 0:
total += digit % 10
digit //= 10
else:
total += digit
num //= 10
return total
num = int(input("Enter an integer: "))

6. Why don't WE need to know exact IP addresses for the devices that we use?
Answer:
We don't need to know the exact IP addresses for the devices that we use because our devices use a network such as the internet to communicate with each other, and the network itself is responsible for routing the data between devices using their IP addresses. When we use our devices to access a network, the network assigns our device a temporary IP address, which is used to identify and communicate with our device within the network. This means that we only need to know the IP address of the network itself, rather than the specific IP addresses of all the devices that we use.
