A more vivid expression is as follows: >>> values=1,2,3>>>1, 2, 3>>> x,y,z=>>>1>>>2>>>3 4. chained assignment Chained assignment is a shortcut to assign the sa

fso| Tutorial How to use the FSO to read files -fso Use tutorial 6 The TextStream object provides three ways to read files: ReadLine, read, and ReadAll. Before calling these methods, you must be aware of the problem with the end of the file----when the contents of the entire file are read, if you call Readline,read, ReadAll, and so on, a "Enter the end of file"

Python provides a standard module, called Pickle. With it you can store any Python object in a file, and then youAnd you can take it out in its intact. This is referred to as a persistent storage object.There is another module called Cpickle, which is functionally identical to the Pickle module, except that it is written in C, soMuch faster (1000 times times faster than pickle). You can use either of them,

variable, which is actually a variable pointing to the function. A variable can point to a function, and the argument of a function can accept a variable. Then a function can receive another function as a parameter, which is called the higher order function. If you point a python built-in function name to another object, you cannot call the function through the variable name and error. The sample code is as follows: >>> ABS ( -10)10>>> abs in functio

CycleTo calculate 1+2+3, we can write an expression directly:>>> 1 + 2 + 36To calculate 1+2+3+...+10, you can barely write it.However, to calculate 1+2+3+...+10000, it is impossible to write the expression directly.In order for the computer to calculate thousands of repetitions, we need to loop the statements.There are two types of
