In Python, we can also import a module by renaming it. For example, Here, We have renamed the math module as m. This can save us typing time in some cases. Note that the name math is not recognized in our scope. Hence, math.pi is invalid, and m.piis the correct implementation.
We can import specific names from a module without importing the module as a whole. For example, Here, we imported only the pi attribute from the mathmodule.
In Python, we can import all names(definitions) from a module using the following construct: Here, we have imported all the definitions from the math module. This includes all names visible in our scope except those beginning with an underscore(private definitions). Importing everything with the asterisk (*) symbol is not a good programming practic...
In Python, we can use the dir()function to list all the function names in a module. For example, earlier we have defined a function add() in the module example. We can use dir in examplemodule in the following way: Here, we can see a sorted list of names (along with add). All other names that begin with an underscore are default Python attributes a...
