Is it possible to find the location of the phone without the Internet?

Question

Python

The idea is this: I want to write a python program that will give me the coordinates of a smartphone (in which the program is also installed).
Can this be done without connecting this smartphone to the internet? Are there any libraries for this?
UPD:
Well, if you have the Internet, how? api google/yandex?
