If you know that there are chances that your code may produce error at the run time due to various unavoidable factors, you can handle those errors elegantly by using a try-except block. For example a divide by zero, connection to db error, page not found error etc.
Consider below example, if the value of y is equal to zero, then the code which divides 100 by ‘y’ will execute. if there is no try catch block, then the program will result into an error as shown below
When you add a try-except block, you can handle the above situation elegantly, without your program crashing with error.

## Example for try-except block y=0 if(y==0): try: print('Result:',100/y) except Exception as exceptionMsg: print('Something went wrong!', exceptionMsg) else: print('Condition is not true') |
