try
In Python, the try keyword defines a block of code that you want to attempt to run, while also providing a way to handle any exceptions that occur. The try block is typically followed by one or more except blocks to catch and handle exceptions. It’s a fundamental tool for managing errors gracefully in your code.
Python try Keyword Examples
Here’s a quick example of using the try keyword with an except block:
>>> try:
... result = 10 / 0
... except ZeroDivisionError:
... print("To infinity and beyond...")
...
To infinity and beyond...
In this example, the code inside the try block attempts to divide 10 by 0, which raises a ZeroDivisionError. The except block catches this exception and prints a message.
Python try Keyword Use Cases
- Handling exceptions that may occur during file operations, such as reading or writing to a file
- Managing errors in network operations, like making requests to external services
- Catching and dealing with arithmetic errors, such as division by zero
