By its very nature, a regular expression (or RE) is a small, highly specialized programming language that is embedded in Python and implemented through the RE module. With this small language, you can specify rules for the set of strings that you

All types in Python exist as objects.There is no char type in Python, only a string type, which makes it very inconvenient for us to convert the char type to integer, but Python already provides built-in functions for these transformations.In Python,

Garbage collection 1. Small integer Object poolIntegers are used extensively in programs, and in order to optimize speed, Python uses a small integer pool of objects to avoid frequent application and destruction of memory space for integers.Python
