sys.maxint in Python - GeeksforGeeks
In Python 2, sys.maxint refers to the maximum value an integer can hold on a given platform. This value is: 2³¹ - 1 = 2147483647 on a 32-bit system; 2⁶³ - 1 = 9223372036854775807 on a 64-bit system; sys.maxint was typically used as a very large number in algorithms requiring an upper bound, like finding minimum values in a list.. Note: sys.maxint has been removed in Python 3.

Fast way of counting non-zero bits in positive integer
def get_bit_count(value): n = 0 while value: n += 1 value &= value-1 return n Share ... at least in this question. -- -- By the way, Python 2's int type maximum value is 2^63-1, so that would definitely not fit in any kind of table; and if you have to use a disk, it's already slower than the slowest algorithm you would ...

Max Int in Python - Delft Stack
The maximum integer value in Python 2 is 2,147,483,647 for a 32-bit system and 9,223,372,036,854,775,807 for a 64-bit system. how does Python 3 handle integers differently than Python 2? Python 3 uses an unbounded int type, allowing integers to grow as large as memory allows, eliminating the need for a separate long type.

Mastering Python’s Maximum Integer Value - Analytics Vidhya
Python 2 (64-bit) int: Maximum value is 263−12^{63} – 1263−1 or 9,223,372,036,854,775,807; long: Only limited by available memory; Python 3. int (both 32-bit and 64-bit systems): Only limited by available memory; This flexibility allows Python 3 to handle significantly larger integers than many other programming languages.

Imposing a hard limit on Python integers
Currently, the upper limit of Python integers is determined by the size of the block of memory that can be theoretically and practically allocated. On 32-bit platforms it is \\frac{15}{2}(2^{31}-1) < 2^{34} bits (2 bytes for every 15 bits). On 64-bit platforms the theoretical limit is \\frac{15}{2}(2^{63}-1) < 2^{66} bits. This requires insane amount of memory. This is much more than any ...

How do you represent the minimum and maximum values for integers in ...
In Python 3, the int type is unbounded, meaning there is no maximum or minimum value like in Java. However, you can use sys.maxsize to get the maximum value a variable of type Py_ssize_t can take. This value is typically 231 - 1 on a 32-bit platform and 263 - 1 on a 64-bit platform. You can use it like this:

Int32: A Deep Dive into Maximum Value and Code Examples
Subtracting 1 gives us the maximum positive integer value. An int32 is a 32-bit signed integer, meaning it can represent numbers from -2^31 to 2^31 - 1. The leftmost bit is the sign bit: 0 for positive numbers, 1 for negative. The remaining 31 bits represent the magnitude of the number. Using Language-Specific Libraries. Python
