What is a pandas country of origin?

The term "pandas" is not a country, but rather refers to a species of bear, the giant panda, which is native to China.

Giant pandas are found in the central mountains of China, mainly in the Sichuan, Shaanxi, and Gansu provinces.

It's important to distinguish between the animal (the giant panda) and the software library (Pandas), which is a data analysis tool used in Python.
