Exception Handling

Exception Handling : Try-except-else-finally

• Try is the keyword which is used to keep the code segment under check
• Except- segment used to handle the exceptions after catching it
• Else- runs this when no exception exists
• Finally- this segment of code is always executed though there is exceptions or not

Example 1

try:
    print(2 / 0)
except NameError:
    print("The given Variable is not defined")
except ZeroDivisionError:
    print("Zero Division Error")
except:
    print(
        "Something gonna wrong"
    )  # This line is executed if some other exceptions are encountered.
else:
    print("Runs when no exception are found")
finally:
    print("Exception handling")

Output:
Zero Division Error

Example 2

else:
    print(100 / 10)
finally:
    print(500 / 5)
