This article mainly talks about "what are the digital types of Python". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "what are the Python digital types"?

I. figures

The number types in Python include:

Integer number

Floating point number

Complex number

Fixed precision decimal number

Rational fraction

Set

Boolean type

Infinite integer precision

Various digital built-in functions and modules

Second, built-in mathematical tools

Expression operator:

Operator description yield generator function delivery protocol lambda args:expression generates anonymous functions x if y else z ternary expression x or y logic or (there is a short circuit algorithm) x and y logic and (there is a short circuit algorithm) not x logic non x in x not in y membership x is ydepartment x is not y object entity test x comparison size x | y bit OR, set union x ^ y bit XOR, set symmetry difference x ^ y bit and The set intersection xy moves to the left or to the right, merging and deleting x quotient, x% y, and so on, multiplies the remainder, divides, divides the floor, divides, subtracts, divides, subtracts, divides, divides Call function x.attr calls attribute () tuple, expression, generator [] list, list parsing {} dictionary, collection, collection and dictionary parsing.
