What does the 'from' keyword indicate when importing in Python?

The 'from' keyword in Python is used to specify a subset of a module to import. This allows you to import specific functions, classes, or variables directly from a module rather than importing the entire module. For example, if you have a module named math, using 'from math import sqrt' allows you to use the sqrt function directly without needing to prefix it with the module name (like math.sqrt).

By importing only the specific components you need, your code can be more efficient and clear, as it directly implies to the reader what functions or classes are being used. This also helps to avoid potential naming conflicts with other imported modules or functions.

In contrast, the other options involve details that do not accurately reflect the purpose of the 'from' keyword in import statements. Renaming modules typically involves the 'as' keyword, suggesting importing all methods would use an asterisk (*) syntax, and restricting access to private methods pertains to object-oriented programming principles rather than module importation.
