A list or tuple can represent an ordered Set. What if we want to access each element of a list in turn? such as List:L = [' Adam ', ' Lisa ', ' Bart ']print l[0]print l[1]print l[2]If the list contains only a few elements, it is OK to write, and if the list contains 10,000 elements, we cannot write 10,000 lines of Print.This is where the loop comes in Handy.The python for Loop can then iterate over each element of the list or tuple in Turn:L = [' Adam

function:>>> Sorted (['Bob',' about','Zoo',' credit'], key=str.lower, reverse=True) ['Zoo',' credit','Bob',' about']As you can see from the above example, the abstraction of Higher-order functions is very powerful, and the core code can be kept very concise.Summary　　sorted()is also a higher-order Function. The key to sorting is to implement a mapping Function. sorted() PracticeSuppose we use a group of tuples to represent student names and scores:L = [('Bob', '), ('Adam', "), ('Bart') , ('

Because Mr. Dening, who was Google's China Test manager two years ago (at the end of 2010), wrote an article on "What is Agile Software Testing" (published on the INFOQ website [1]), which has already been discussed, "Agile software testing is more of a concept than a process." [2] In 2011, I wrote an article on "thinking and new developments in agile Testing", published in

Serialize () and unserialize () are explained in the PHP Manual: Serialize-generates A storable representation of a valueserialize-produces a representation of a value that can be storedUnserialize-creates a PHP value from a stored representationunserialize-to create PHP values from a stored representationObviously, the interpretation of "a stored representation" has been translated into a value that can be stored and remains very confusing.Use an example to see how these two functions are used:

example illustrates two scopes: insert on T1 and insert on T2 as the trigger result. Assume that both T1 and T2 have the identity column. @ identity and scope_identity return different values at the end of the insert Statement on T1. @ Identity returns the value of the last identity column inserted to any scope in the current session. This value is the value inserted in T2. Scope_identity () returns the identity value inserted in T1, which is the last insert that occurs in the same scope. If

mentioned above, the collaborative filtering algorithm is used to identify people with close interests from many people. The first step is to show the interests of individuals and others so as to facilitate subsequent data processing. The general practice is to treat everyone as a vector, and each feature point of interest is regarded as one-dimensional vector. All interests need to be quantified here, otherwise data cannot be computed and processed. for example, if you like it very much, mark

hours and sleeping for 15 minutes. In this way, a total of 1.5 hours of sleep is required, and a lot of time is spent chasing the joy of his own heart. Future studies show that such sleep does not harm health at all. Unfortunately, his talents could not be understood by others in that era. Most of his research results were not made public, and his kidney had to write notes in a hidden language. As a result, people's research gradually caught up with him. 　　　　 Interestingly, since leaving Venic
