On my way to build an OpenAI ChatBot with Python I need to get better with coding, and for that I now started doing daily short exercises. Right now I’m getting them from ChatGPT. Here is a small Factorial Calculator I just made. (I know the logging is probably overkill but I just want to get in the habit of using that haha).
Do you know any other libraries I should learn to use or fun little exercises you think I should do?
# Exercise: Factorial Calculator
import logging
# Configure logging
logging.basicConfig(filename='factorial_calculator.log', level=logging.ERROR, format='%(asctime)s - %(levelname)s: %(message)s')
def calculate_factorial(number): # Calculate the factorial of a non-negative integer.
if number < 0:
return 'Not Defined (Factorials are not defiend for negative numbers)'
elif number == 0:
return 1
result = 1
while number > 1:
result = result * number
number = number - 1
return result
def main():
while True:
user_input = input('input: ')
try:
number = int(user_input.strip())
break
except ValueError:
logging.error('ValueError: Please enter a number')
print(f'factorial: {calculate_factorial(number)}')
if __name__ == '__main__':
main()
