standard Library, as well as binary forms of various platforms, can be obtained from the official Python website: https://www.python.org/free of charge, and you are free to spread these things.The site also contains suggestions from many people about the modules, programs, and tools that face Python 3, as well as a variety of additional documentation.

(func)即可。Two: Partial function (one of functools the functions in the module)1在介绍函数参数的时候，通过设定参数的默认值，可以降低函数调用的难度。而偏函数也可以做到这一点。2 int() Functions can convert a string to an integer, and when passed in only the string, the int() function defaults to decimal conversion:int(‘12345‘)12345But int() the function also provides additional base parameters, the default value is 10 . If you pass in base a parameter, you can do an n-binary conversion: >>> int ( ' 12345 ', base= 8) 5349 #把字符串当做8进制 and returns t

the state of execution, and with this, writing a generator can implement functionality that requires an object-oriented implementation. For example, use an object to save the state, so write:var fib = { a: 0, b: 1, n: 0, max: 5, next: function () { var r = this.a, t = this.a + this.b; this.a = this.b; this.b = t; if (this.n this.max) { this.n ++; return r; } else { return undefined; } }};It is quite tedious to use the properties of the object to save the state.Another great benefit

, this is recommended unless the module being imported needs to use sub-modules with the same name from different packages.6.4.2 reference of built-in packages When the package is structured into a sub-package (like the sound package in the example), you can use absolute imports to reference the module of the brother package. For example, if the module sound. Filters. Vocoder needs to use the echo module in the package sound. effects, you can use from sound. Effects import echo. You can also wri

ReadLine () method to read line by row, reading one line at a time, and then moving the pointer to the beginning of the next line. The ReadLines () method stores the results of the read as a list, and when it is finished, the pointer moves to the next bit at the end of the file. Each line in the original file is a return element in the list. Append write using ' A ' mode, after opening the file, the pointer still refers to the file header, after the write () method is written into the string, t

same linePython can use multiple statements in the same row, with semicolons (;) split between statements, and here's a simple example:Import ' Runoob ' ' \tabc\n ')Print outputThe print default output is newline, and if you want to implement no wrap, you need to add a comma to the end of the variable:Multiple statements form a code groupIndenting the same set of statements constitutes a block of code, which we call the code group.Compound statements such as if, while, Def, and class, the first

Concise Python tutorial --- 6. Control Flow In python, there are three control flow statements: if, for, and while. If statement The IF statement is used to detect a condition. If the condition is true, the program jumps to execute a statement block (called the if statement block ), otherwise, the program will jump to

indented is the way python uses grouping statements. At the interactive prompt, you have to enter a tab or several spaces for the contraction. In practice, you need a text editor to prepare more complex input. All the better text editors have the automatic indent function. When a compound statement is input interactively, it must be followed by an empty line (because the parser cannot guess when you enter the last line ). Remember, each line in a bas

global variables is generally not a problem. However, 1, if the name of a local variable or parameter is the same as the global variable name you want to access, you cannot access it directly. Global variables are masked by local variables. If you do, you can use the GLOBALS function to get the global variable value. 2. Re-bind global variables. Function nesting: One function is in the other, and the outer function returns the inner function. This means that the function itself is returned, bu
