In Python, is it possible to define an alias for an imported module?
For instance:
import a_ridiculously_long_module_name
...so that is has an alias of 'short_name'.

import a_ridiculously_long_module_name as short_name
also works for
import module.submodule.subsubmodule as short_name

Hmm, when I try to do
from name import X (after the alias definition) I get No module named name. Can we import modules from aliases?

It seems you can't, here is the clearest answer I found for that stackoverflow.com/a/40823467
If you've done:
import long_module_name
you can also give it an alias by:
lmn = long_module_name
There's no reason to do it this way in code, but I sometimes find it useful in the interactive interpreter.

For some purposes this is better than the top answers (import long_module_name as lmn) because you can still reference the module by both long_module_name.x and lmn.x

This is the technically correct response for the question: aliases for imported modules.

The reason this is possible is that modules are first-class objects in Python.

For unknown reason you package aliasing does not work. Later I can not import subpackages by that name with "from" and "dot" (from lmn.some_sub_name import york).
Yes, modules can be imported under an alias name. using as keyword. See
import math as ilovemaths # here math module is imported under an alias name
print(ilovemaths.sqrt(4)) # Using the sqrt() function

Yes, you can define aliases for imported modules in Python.
Using pandas is considered a best practice in python because Pandas can import most file formats and link to databases.
Example: Import pandas library
import pandas as pd
Explaining:
pd: is the conventional alias for pandas.
NP: is the conventional alias for Numpy.
Using short alias helps keep code (concise) and (clean).
