What is the maximum possible value of the int data type in Python?

In Python 3, the int type does not have a fixed maximum value, as it is implemented as an arbitrary-precision integer. This means that the limit on the maximum value depends only on the available memory in the system, not on a fixed size type as in other languages.

Example:

x = 10**100  # Very large number
print(x)

Here, x is an integer with 101 digits, and Python handles it correctly.
