When it comes to quick sorting, it really takes a lot of effort to see and understand. The sorting algorithm is quite complex, and understanding it is like peeling onions, one layer at a level. OK, let's talk about the principle of the

Look at so many insert sorts, explain this method.There are several steps:1 think the previous sequence has been sorted, that is, in order from small to large, the largest in the last side2 Save the next number of a[i] into a variable, a[i] = data.

Learning other languages with little attention to arrays is how the structure is going to be used directly. Python defines three data structures for lists, tuples, and dictionaries, and is the basis for our use of Python, so it is necessary to

Caller What does that mean? callable (obj)        if obj as code  or function static method differs from class method   object variable class  , immutable class what can do type of key key, hash type class with hash ()

Strings provide a series of methods to implement complex text processing tasks. A method is a function that is associated with a particular object. The method call performed two operations at the same time:First time: Property read-An expression

Python Sequence list and tuple common methods and precautions, pythontuple Sequence Sequence is a set of ordered objects. A sequence can contain one or more elements, or contain no elements. The basic data types we mentioned earlier can all be used

In Python, unittest is used to generate a separate test case based on different parameter combinations.In some cases, you need to use different parameter combinations to test the same behavior. You want to know what to test from the test case
