This article mainly introduces how to use the for Loop in Python. It is the basic knowledge in getting started with Python. If you need it, you can refer to the for loop projects that traverse all sequences in Python, such as a list or a string.
Syntax:
The for loop syntax is as follows:
for iterating_var in sequence: statements(s)
If a sequence contains a list of expressions, calculate the first one. Then, the first item in the sequence is allocated to the iteration variable iterating_var.
, the computing results are gradually produced, and complex operations are derived layer by layer. -Your Excellence has nothing to do with my life. Please take your arrogance. The following is an example of the output array shoplist = ['apple', 'mango ', 'carrot', 'Banana'] print 'my shopping list is now ', shoplist # output # My shopping list is now ['banana ', 'carrot', 'mango', 'Rice']. This code is easi
a single code block. Python uses indentation as its statement grouping method.
Example:
#!/usr/bin/pythonfor letter in 'Python': # First Example print 'Current Letter :', letterfruits = ['banana', 'apple', 'mango']for fruit in fruits: # Second Example print 'Current fruit :', fruitprint "Good bye!"
The output result is as follows:
Current Letter : PCurrent Letter : yCurrent Letter : tCurrent Letter : hCurrent Letter : oCurrent Letter : nC
An example of how to convert array elements into strings in JavaScript is provided.
First, let's take a look at the method slice () for selecting elements from an array ():Source code:
Test results:
Orange,Lemon
We can use array elements to form a string. The related join () method is used as an example:
Source code:
Test results:
Banana,Orange,Apple,Mango
To directly convert an array to a string, you can use the toString () method:Source code:

script.
Use buttons, menus, and other entries to quickly expand the user interface
One of the best features of idea is to allow everyone to use their own scripts and quickly hook them into the UI elements in the IDE-as new buttons or new menu entries. You don't need to write Java code or use a new plug-in. You just need to add a few lines of content to the script title-that's easy.
The following example uses a simple script to create three new projects for us:

Basic YAML syntaxHttp://ansible-tran.readthedocs.io/en/latest/docs/YAMLSyntax.htmlYAML also has a small quirk. All YAML files (regardless of whether they have a relationship with Ansible) should be started --- . This is part of the YAML format, which indicates the beginning of a file.All members in the list start at the same indentation level and use one "-" as the beginning (a bar and a space):---# A list of delicious fruit notes using #AppleOrangeStrawberryMango A dictionary is made 键:值 up

Copy of JS Array (does not affect the original array), array equivalence judgment array copyAn array is a reference type; A simple assignment simply adds a pointer to an array; ex:var a = [1,2,3];var b = a;b.push(2);console.log(a)//[1,2,3,2]对新数组 b 的操作同样会改变原始数组 a So how do you implement a separate copy? The following two methods are introduced: the performance of the two methods is not small, different browser cores are unique://method 1var a = [1,2,3];var B = a.slice (); A.reverse;console.log (a
