Is it possible in Python importing a module by using a fuction or a class?

Question

Is there any possible way like defining a function like:
"""
def importer(module):
return import module
"""
This does not work because module comes as string. "module" you cannot use like:
import "module"

Does anyone know how to fix it?

Answer 1

This might be the one you are looking for.

def importer (module ):
__import__(module)

The __import__ function can import modules from variables and strings containing module names

Answer 2

You don't be mandatory to import module at very start of your Python code, so yes you can... but:

return import module

... will not work as expected because it doesn't return any value ^^

Anyway, you cannot import a module as a string but you can do:

def import_mod():
import module
def import_mod1():
import module1
def import_mod2()
import module2
import_list = {
'module': import_mod,
'module1': import_mod1,
'module2': import_mod2
}
mod = 'module1'
import_list[mod]()

But anyway, the imported module will be available only within the function scope :(

... And, by the way, it's not 'pythonic':

PEP8 wrote: << Imports are always put at the top of the file, just after any module comments and docstrings, and before module globals and constants. >>
