DescriptionJsoi gave the team ZYX a task. Compile a computer software called a "text generator": The software is used by a few young people who are now using the GW Text Generator version V6. The software can generate some random articles----always generate a fixed length and completely random article-
as follows:1090[1, 2, 3, 4, 5, 6]List methodIn Python, there are a number of methods for list processing, let's look at an example:
Append (obj)Add a new object at the end of the list
Count (obj)Number of occurrences of an element in the statistics list
Extend (SEQ)Append another sequence (that is, List extension) at the end of the list
Index (OBJ)Returns the index of the first matching element in a list
Insert (index, obj)In
a string object is not slower than the StringBuffer object, especially in the following string object generation, where string efficiency is far faster than StringBuffer: string S1 = "This is only a" + "simple" + "Test"; StringBuffer Sb = new StringBuilder ("This was only a"). Append ("simple"). Append ("test"); See also: http://www.findspace.name/easycoding/1090
