Hints

• Use a Loop:

  • Implement a while loop to continuously prompt the user for input until they choose to exit.

• Utilize eval():

  • Use the eval() function to evaluate the mathematical expression entered by the user. Be cautious about input validation.

• Error Handling:

  • Use try-except blocks around the eval() call to handle potential errors, such as division by zero or invalid input.

• User Input:

  • Prompt the user to enter a mathematical expression and provide a clear option to exit (e.g., type 'exit').

• Print Results:

  • After evaluating the expression, print the result back to the user in a clear format.
