This article will show you the easiest ways to learn Python max int and how to obtain the maximum integer value in various Python versions. In Python 2, there’s a max limit in int. When the value of an integer reaches 231 – 1, its data type changes automatically to long integers, and no exception is thrown.
Moving on, when the data type of a variable is changed to “long,” it can be as big as the machine can hold. It means that long data types in python 2 have no limit.
Anyway, in Python 3, there is no difference between the integer and long data types. This means that when the limit of 231 – 1 is reached, the datatype of a variable will not change.
However, the integer in Python 3 works the same way as the long in Python 2, and it can store values as big as the machine can hold.

Get python integer maximum Using the sys Module
Below is the example to get the maximum integer in python 2 using
the equal to
231 - 1:
import sys print(sys.maxint)
What is the max int in Python?
The max int limit in Python 2 is 9223372036854775807, and everything above this value will be converted directly to long.
Also, In Python 3,
sys.maxint does not exist since the data type integer has no longer a limit. In Python 2 and 3, however, we may use
sys.maxsize to obtain the maximum value of the
Py_ssize_t type. It is also the maximum size that lists, strings, and dictionaries can have.
How do you give Max int in Python?
We can get the max int in python by using
sys.maxint , it only works in python 2. However, in python 3, the int doesn’t have
sys.maxint because it doesn’t have a
sys.maxsize , to get the maximum value of the
Py_ssize_t type in Python 2 and 3.
Example: Python 3 Max int Limit
# Python 3 Max Int import sys print(sys.maxsize) print(type(sys.maxsize))
9223372036854775807 <class 'int'>
How do you print max numbers in Python?
Example of how to print max numbers in python:
import sys if sys.maxsize == 2**63 - 1: print("It is a 64-bit computer.") if sys.maxsize == 2**31 -1: print("It is a 32-bit computer.") print("The type of sys.maxsize is",type(sys.maxsize)) print("The value of sys.maxsize is",sys.maxsize)
It is a 64-bit computer. The type of sys.maxsize is <class 'int'> The value of sys.maxsize is 9223372036854775807
The output shows that the computer is 64-bit where the script has been executed. The type of
sys.maxsize is int, and the value of
sys.maxsize is 9223372036854775807.
In conclusion, we learned that in python 2, there is a maximum int. If it exceeds its limit, int to long data types are automatically switched, while Python 3 has unlimited precision, which means there is no explicitly defined maximum int.
The integer and long data types are the same. This means that even if it exceeds its limits, there are no changes in data types.
