Add advertising hereExceptions are errors detected during execution. Python provides a way to handle exceptions using try
, except
, else
, and finally
blocks.
Basic Exception Handling:
try:
# Code that might raise an exception
result = 10 / 0
except ZeroDivisionError:
# Code to handle the exception
print("Error: Division by zero is not allowed.")
Handling Multiple Exceptions:
try:
# Code that might raise an exception
num = int(input("Enter a number: "))
result = 10 / num
except ValueError:
print("Error: Invalid input. Please enter a number.")
except ZeroDivisionError:
print("Error: Division by zero is not allowed.")
else:
# Executes if no exceptions occur
print(f"Result is {result}")
finally:
# Executes regardless of exceptions
print("Execution complete.")
Raising Exceptions:
def divide(a, b):
if b == 0:
raise ValueError("Argument 'b' must not be zero.")
return a / b
try:
divide(10, 0)
except ValueError as e:
print(e)
