answer:Python is unique among mainstream modern programming languages because it doesn’t have integer overflow. Here’s what I mean by that. In most other programming languages, there is a distinct “maximum integer” that can be displayed. That is, if you try to display too high of an integer (beyond that which can fit in 32 bits, or 2^31–1), the integer will actually wrap around back to the minimum integer, or -2^31. That is, 2^-31–1 + 1 = -2^-31, even though this is mathematically fallacious. This happens because there simply isn’t enough memory to hold a larger number. But Python is different. Python keeps allocating more and more memory to your integer to accommodate its larger size. But there is still a limit – albeit a ridiculous one – the amount of memory available to your program. And that’s the limit I expect you’re hitting. The integer is eating up all the available memory and the program is unable to continue.
