Practice:Here is a topic from the Basic Python tutorial:>>> girls = ['Alice','Bernice','Clarice']>>> Boys = ['Chris','Arnold','Bob']>>> [B +'+'+g
execution p (100) eventually returns 123.
Now we have closed the possibilities behind a suggested interface.
>>>digits_only = Translator (keep = string.digits)
>>>digits_only (' Chris perkins:224-7992 ')
' 2247992 '
Removing elements that belong to a character set is also very simple:
>>>no_digits = Translator (delete = string.digits)
>>>no_digits (' Chris perkins:224-7992 ')

global variables and two global functions:
Copy Code code as follows:
var name = ' Chris ';
var age = ' 34 ';
var status = ' single ';
function Createmember () {
// [...]
}
function Getmemberdetails () {
// [...]
}
If there is a variable called status in other scripts on this page, the trouble arises. If we encapsulate them in a myapplication, the problem is solved:
Copy Code code as follows:
var
and rewrite the variable (ECMA's JavaScript 5 has changed this situation-the translator), Using anonymous functions, you can bypass the problem.
For example, you have such a piece of code, obviously, variable name, age, status will become global variables
Copy Code code as follows:
var name = ' Chris ';
var age = ' 34 ';
var status = ' single ';
function Createmember () {
// [...]
}
function Getmemberdetails () {
// [...
For the boys who have the fashion requirements, how to wear is enough to have the type and the glory of the king is as important as the number of things.
Weekday commute to work, night with women's tickets, the weekend also occasionally hit a point of leisure and entertainment activities. How to pick the right outfit at the right time and occasion becomes particularly important; the boys ' wear is not as unique as the girl's talent and enough diligence.

Mom doesn't have to worry about my closures anymore.注:本文为作者自己总结,过于基础的就不再赘述 ,都是亲自测试的结果。如有错误或者遗漏的地方,欢迎指正,一起学习。The closure in Swift is a very powerful thing, and closures are self-contained blocks of function code that can be passed and used in code. Similar to code blocks (blocks) in C and Objective-c. We must master this! Must master! Must master!重要的事情要说三遍Closures can capture and store references to any constants and variables in the context in which they are located. This is called closed merge

The general way to define a struct is as follows:struct { field1 type1 field2 type2 ...}type T struct {a, b int}It is also a legal grammar, which is more suitable for simple structures.var t *new(t)A variable t is a T pointer to a struct field whose value is the 0 value of the type they belong to, and uses the new function to allocate memory to a newer struct variable, which returns a pointer to the allocated memory.Regardless of whether the variable is a struct type or a struct type po
