Project 1: Basic Calculator
4. Enhancing User Experience
A basic calculator is functional now, but let's make it a bit more user-friendly:
- Error Handling: We should handle potential errors, such as when the user enters a non-numeric value.
- Result Formatting: Display the result in a more readable format.
Let's implement these:
# ... previous code ...
if user_input in ('add', 'subtract', 'multiply', 'divide'):
try:
x = float(input("Enter first number: "))
y = float(input("Enter second number: "))
if user_input == 'add':
print(f"{x} + {y} = {add(x, y)}")
elif user_input == 'subtract':
print(f"{x} - {y} = {subtract(x, y)}")
elif user_input == 'multiply':
print(f"{x} × {y} = {multiply(x, y)}")
elif user_input == 'divide':
print(f"{x} ÷ {y} = {divide(x, y)}")
except ValueError:
print("Please enter a valid number.")
else:
print("Invalid Input")
# ... rest of the code ...We've wrapped our number input section with a try...except block to handle any ValueError exceptions. This ensures the program doesn't crash if a user accidentally (or intentionally) enters non-numeric values. We've also added formatted strings to display the result in a clearer manner.
With these enhancements, our basic calculator is now more resilient and user-friendly! As you work through this project, remember that it's not just about creating a tool that works; it's about creating a tool that provides a smooth experience for its users.
