Detailed explanation of basic knowledge of functions
1. What is a function
A function is an organized, reusable piece of code that implements a single or related function. Functions can improve the modularity of the application and the reuse rate of the code. In the previous article, we have used the built-in functions provided by python, such as print(). But you can also create your own functio ...

python process control
1. Comparison operation
For the python language, all objects support comparison operations, which can be used to test equality, relative size, etc. If it is a conforming object (such as: tuple, list), python will check all its parts, including automatically traversing all levels of nested objects until the final result can be ob ...

Python Basics - Numpy Numerical Calculation
NumPy provides a multidimensional array object called ndarray whose elements have a fixed size. That is, NumPy array elements are homogeneous and can only store objects of the same data type. It can use vectorized operation to process the entire array, which has high operation efficiency.

Create an ndarray array through the arr ...
