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 sys.maxint
, 231 - 1
:
import sys
print(sys.maxint)
Output:
9223372036854775807
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
maximum limit in integer. Yet, we can use 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))
Output:
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)
Output:
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.
Conclusion
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.
