Let's knock this out.
Here are the Python programs for your requests:
1. Cumulative Sum Program
cumulative_sum = 0
print("Cumulative sums divisible by 5 (until sum exceeds 200):")
for i in range(101): # Loop from 0 to 100
cumulative_sum += i
if cumulative_sum % 5 == 0:
print(f"Current cumulative sum: {cumulative_sum}")
if cumulative_sum > 200:
print(f"Cumulative sum {cumulative_sum} exceeded 200. Terminating.")
break
Explanation:
Step 1: Initialize cumulative_sum to 0.
Step 2: Loop through integers from 0 to 100 using range(101).
Step 3: In each iteration, add the current integer i to cumulative_sum.
Step 4: Check if cumulative_sum is divisible by 5 using the modulo operator (%). If the remainder is 0, print the sum.
Step 5: Check if cumulative_sum has exceeded 200. If it has, print a termination message and use break to exit the loop.
2. Number Guessing Game
import random
secret_number = random.randint(1, 10) # Generates a random number between 1 and 10
# You can also set a fixed secret_number = 7 for example
print("Welcome to the Number Guessing Game!")
print("I'm thinking of a number between 1 and 10.")
while True:
try:
guess = int(input("Enter your guess: "))
if guess == secret_number:
print(f"Congratulations! You guessed the correct number: {secret_number}")
break # Exit the loop if the guess is correct
else:
print("Incorrect guess. Try again!")
except ValueError:
print("Invalid input. Please enter an integer.")
Explanation:
Step 1: Import the random module to generate a secret number between 1 and 10.
Step 2: Start an infinite loop using while True, which will continue until explicitly broken.
Step 3: Prompt the user to enter their guess. The input is converted to an integer. A try-except block handles potential ValueError if the user enters non-numeric input.
Step 4: Compare the guess with the secret_number.
Step 5: If the guess is correct, a congratulatory message is printed, and the break statement terminates the loop, ending the game.
Step 6: If the guess is incorrect, a "Try again!" message is displayed, and the loop continues for another guess.
