Which module of Python is fast and consumes less time, pandas or numpy ??

Question

And where should i use them?

Answer 1

These two modules are different but they work together. Most function or attributes of Pandas Module highly depends on Numpy.

It depends on what you want to do:
Numpy --> If you want to easily manipulate numerical data
https://numpy.org/
https://numpy.org/doc/stable/user/whatisnumpy.html

Pandas --> If you want to easily manipulate Tables\frames (e.g. CSV) consisting of different data
https://pandas.pydata.org/
