" functions. In other words, they operate on some functions, and these functions operate on other functions ). Function programming advocates believe that all these features lead to faster development of less code and fewer errors. Moreover, senior theoretical scientists in computer science, logic, and mathematics have discovered that the formal performance of fu

simpler design than Perl, this makes Python more readable, easier to maintain, and helps reduce program bugs. Simpler and easier to use than Java, Python is a scripting language, and Java inherits a lot of syntax and complexity from system-wide languages like C + + Simpler and easier to use than C + +, but usually does not compete with C + +, because Python,

like different things and it is better to unify them. After the definition of each class or function, the first line can be a description statement without the annotator mark. For the statement followed by the block statement, it should be followed by a colon. A row of statements cannot be too long because there is no line terminator. If it is too long, use the line break (\). There are also some interesting examples, such as the following comparison processing,
