The else block executes when the try block executes successfully without any exception; otherwise, it skips the code.
The finally block always executes, regardless of errors occurring.
Now you can clearly understand how else and finally block with the help of this flowchart.
Start | v Write code in the Try block | v Run Try block | v Is there any error? / \ Yes No | | v v Run Except Run Else block block | | v v Try finishes Handle error / Show error | v Run the Finally block | v End
Syntax
try:
# risky code
except ExceptionType:
# error handling code
else:
# runs if no error in try
finally:
# always runs
Example
try:
num = 40
result = num + 10
except Exception:
print("Error")
else:
print("Else block: Result =", result)
finally:
print("Finally block: always executes")
Output
Exercise
Write a Python program using try, except, else and finally block. In try block divide 10 by 2 and print result.
