The >>> sign in Python code. What is it?

Question

Python

Good day!
Another idiotic question.
Very often, looking for various examples of Python code on the Internet, I stumble upon a mysterious icon: >>>.
For example:

>>> import pandas as pd
>>> my_series = pd.Series([5, 6, 7, 8, 9, 10])
>>>

my_series error.
I ask for tips from dear members of the forum, what are these arrows, what do they mean and why are they needed?
Thank you.

Answer 1

This means that the code was executed directly in the python interpreter.

(Without writing it to a file and running it)
You need to copy, of course, without these characters.

Answer 2

Answer 3

Man, when you go to the console (even without studying it I know), you see these characters in the input field there, it means your input, like write that code without these icons and there will be no error))
