as
In Python, the as keyword creates an alias or alternative name for a module, exception, or context manager. This can make your code more readable and descriptive.
Python as Keyword Examples
Here’s a quick example of using the as keyword with the import statement:
>>> import numpy as np
>>> np.array([1, 2, 3])
array([1, 2, 3])
In this example, you import numpy with the alias np. Now, you can use np as a shorthand for numpy. This is particularly useful for modules with long names.
Another example is using as in exception handling:
>>> try:
... x = 1 / 0
... except ZeroDivisionError as error:
... print(f"Caught an exception: {error}")
...
Caught an exception: division by zero
Here, the as keyword assigns the exception object to the variable error, which you can then use to access information about the exception.
