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

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?

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

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. >> source: https://www.python.org/dev/peps/pep-0008/
