The basic syntax for a for loop is as follows: A common example is looping over the numbers one through five and printing them to the screen: In other programming languages, the syntax for a for loop will look a little different. The Python operators for these are all keywords: Python code was designed for readability. There are so many keywords that python supports like: break, if, else, pass, finally etc. and, or , not. When you catch the TypeError, you re-raise the exception after printing a message to the screen. python. The assert keyword in Python is used to specify an assert statement, or an assertion about an expression. You could modify mpg() to include a finally block that does just that: Now, no matter how mpg() is called or what the result is, you print the arguments supplied by the user: The finally keyword can be a very useful part of your exception-handling code. These are except, else, and finally: A try block isn’t valid unless it has at least one of the other Python keywords used for exception handling as part of the overall try statement. Unsubscribe any time. It’s the equivalent of a no-op, or no operation. In addition to using the else keyword with conditional if statements, you can also use it as part of a loop.
