The sys.maxint constant was removed, since there is no longer a limit to the value of integers. However, sys.maxsize can be used as an integer larger than any practical list or string index. It conforms to the implementation’s “natural” integer size and is typically the same as sys....

❝~((a % MIN_INT) ^ MAX_INT) 这里为什么要对负数做这样的处理呢? 因为在 Python 中 int 不是 32 位的,所以一个负数比如 -2, 其 64 位表示就是 0x00000000FFFFFFFE, 用 Python 求取这个 16 进制的值 int('0x00000000FFFFFFFE', 16), 得到的数字是 4294967294 不是我们想要的 -2,所以:(a ...

Q2. What is the use of the max() and min() functions in Python? We use Python’s max() and min() functions to get the maximum or minimum object out of a set of objects or max/min object out of objects in a given iterable. Q3. What is the difference between the Python max()...
