Gives an error when python code is valid in VS code, why?

Question

Python

There is a code:

age = 23
print(age)

There is an error:

>>> print(age)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'age' is not defined

At the same time, this error is only in VS code, what should I do?

Answer 1

Enter the text of the program in one window, and execute other code in the console.
