Try-except blocks can slow down your code, so it’s best to avoid them when possible. Use conditional statements to handle errors instead.

# Bad Code
def divide(a, b):
try:
result = a / b
except ZeroDivisionError:
result = None
return result
# Good Code
def divide(a, b):
if b == 0:
return None
else:
return a / b
The bad code uses a try-except block to handle the case where the denominator is zero. This method can be slow and inefficient, especially if the try-except block is in a frequently called function. The good code, on the other hand, uses an if-else statement to check if the denominator is zero before performing the division. This is a much faster and more efficient way to handle the zero denominator case.
