Why is the alias 'pd' commonly used for importing pandas?

The alias 'pd' is commonly used for importing the pandas library for convenience and brevity. It allows users to reference the library with a shorter name, making the code cleaner and easier to read. For example, instead of writing pandas.DataFrame(), you can simply write pd.DataFrame(). This convention has become a standard practice in the Python community, making it easier for others to understand and collaborate on code that uses pandas.
