WebPython supports a "bignum" integer type which can work with arbitrarily large numbers. In Python 2.5+, this type is called long and is separate from the int type, but the interpreter will automatically use whichever is more appropriate. In Python 3.0+, the int type has been dropped completely.. That's just an implementation detail, though — as long as you have …
WebYes, ASCII characters are stored by their value. But storing 'A' (65 = 0x41) may be different than storing 65 itself, and how it is done depends on your machine architecture. A char can be stored with a single byte, while a int will be at least 2 bytes (more commonly 4 bytes in modern machines), and so these may be stored differently. It doesn't. ipc in medicine meansWebI am in the process of reducing the memory usage of my code. The goal of this code is handling some big dataset.
