Query About datetime module in Python

[Tanzeem]

Hey hi,

My name is Tanzeem Khan from India.

I am an intermediate python programmer,
I have 2 questions regarding datetime module and time module.

1. What is the difference between datetime.datetime.now() and datetime.datetime.today()?

2.  What is the difference between time,time() and time.perf_counter()??

Please respond.

Thank you

Huge Love from India
