This article mainly introduces the usage of list loop statements in python, and describes in detail the list parsing of Python in the form of examples, including various common traversal operations and principle analysis, for more information about the list statement usage in python, see the following example. Share it with you for your reference. The usage analysis is as follows:

Demo function: ios infinite loop paging source code example. Iphone 6.1 passed the test.
Demo Description: The main page control code in MyScrollView. m. Use the UIScrollView and UIPageControl controls. You can set the starting coordinate of uiscrollview content at the end of the rolling process to implement an unlimited loop.

Next, we recognize what a dead loop is."Dead cycle" means the endless execution of the program, in any case can not jump out of a phenomenon of the loop body. At present, there seems to be no algorithm, for any program can be judged whether
The following is an example of JS's practical line-by-line text loop rolling effect:
JS practical row-by-row text scrolling with pauses
Welcome to the practical line-by-line text scrolling EffectA pause occurred while rolling one row to another.I hope everyone will like it and feel very concise code. Script window. onload = function () {new Marquee ("scrollBox2", // container ID0, // scro
--)
For (t = 5-i; t> = 1; t --)
{
Document. write ("");
}
For (j = 1; j
Document. write ("*");
}
Document. write ("");
}
You can use the for loop to implement some related images.
For example, print the diamond:
*
***
*****
*******
*********
*******
*****
***
*
// Print the diamond Graph
For (I = 1; I
// Print space
For (t = 1; t
Document. write ("");
}
For (j = 1; j
Document. write ("*"

The foreach basic syntax is as follows:
FOREACH ($array _variable as $value)
{
[Code to execute]
}
Or
FOREACH ($array _variable as $key = $value)
{
[Code to execute]
}
In both cases, multiple [code execution] will be executed to be equal to the number of elements in the $ array_variable array.
Let's take a look at an example. Let's say we have the following code snippet:
Copy CodeThe code is as follows:
$array 1 = array (1,2,3,4,5);

PHP array is more commonly used, so I studied the PHP array loop operation, here to share with you, I hope to be useful. PHP is basically an array language. Often to do a large number of PHP array loop operation, there are two main ways, one is foreach, the other is while, in the end what kind of good what kind of bad has been arguing, although I have long been aware of this problem, but has been no scrutin

, the EXPR3 may also be left blank, and can be used to write more complex iterations, such as invoking different iterations based on different conditions.
The conditional statement in the For statement expr2 empty is the above-mentioned infinite loop, of course, you can add some more complex conditions to determine when to jump out of the loop, there is no repetition.
