Python: Lazy import of modules

Question

I earlier researched lazy import of modules and found this way of doing it:

def some_funk():
    lazy_module = __import__("lazy_module")
    lazy_obj = lazy_module.LazyClass()
    lazy_obj.do_stuff()

Then I've seen some examples simply using:

def some_funk()
    import lazy_module
    lazy_obj = lazy_module.LazyClass()
    lazy_obj.do_stuff()

I prefer the later use and will rewrite my code to this.

But my question is if there is any difference between the two ways of doing lazy imports

Your first example should be `lazy_module = __import__("lazy_module")` without `.lazy_module`. — sanyassh, Oct 03 '19 at 10:10

You might want to check the documentation for import out. import lazy_module is internally calling __import__("lazy_module").

The lazy part of the import comes from both of them being done in a function, and not in the top of the class/script.
