How are exceptions handled in Python?

Exception Handling Flow
try block
Code that might raise an exception goes here.If no exception happens, Python skips the except blocks.
except block(s)
Handle specific exceptions.You can have multiple except clauses to catch different error types.The exception object (as e) contains details about what went wrong.
else block
Runs only if no exception was raised in the try block.Useful for code that should execute only when the try succeeded.
finally block
Runs always, whether an exception occurred or not.Commonly used for cleanup (closing files, releasing resources, etc.).
Your Example
try:
    x = 1 / 0
except ZeroDivisionError as e:
    print("Error:", e)        # runs because division by zero happens
else:
    print("No error")         # skipped because an exception occurred
finally:
    print("Always runs")      # always executes
Output:
Error: division by zero
Always runs
More Examples
Multiple except clauses:
try:
    num = int("abc")
except ValueError:
    print("Invalid number")
except ZeroDivisionError:
    print("Division by zero")
Catching all exceptions (not always recommended):
try:
    risky_operation()
except Exception as e:
    print("Something went wrong:", e)
So in short:
try → attempt risky codeexcept → handle specific errorselse → runs only if no errorfinally → always runs (cleanup)
