What is the maximum possible value of an integer in Python ?
Consider below Python program.
Python3
x = 10000000000000000000000000000000000000000000
x = x + 1
print (x)
|
Output :
10000000000000000000000000000000000000000001
In Python, value of an integer is not restricted by the number of bits and can expand to the limit of the available memory (Sources : this and this). Thus we never need any special arrangement for storing large numbers (Imagine doing above arithmetic in C/C++).
As a side note, in Python 3, there is only one type “int” for all type of integers. In Python 2.7. there are two separate types “int” (which is 32 bit) and “long int” that is same as “int” of Python 3.x, i.e., can store arbitrarily large numbers.
Python
x = 10
print ( type (x))
x = 10000000000000000000000000000000000000000000
print ( type (x))
|
Output in Python 2.7 :
<type 'int'>
<type 'long'>
Python3
x = 10
print ( type (x))
x = 10000000000000000000000000000000000000000000
print ( type (x))
|
Output in Python 3 :
<type 'int'>
<type 'int'>
