A nested list refers to a list of nested lists, such as:
The code is as follows:
>>> L = [[1,2,3],
[4,5,6],
[7,8,9]]
Example 1: A nested list of men's and women's lists, taking out names with more than two letters E, composing lists
The code is as follows:
names = [[' Tom ', ' Billy ', ' Jefferson ', ' Andrew ', ' Wesley ', ' Steven ', ' Joe '],
[' Alice ', ' Jill ', ' Ana ', ' Wendy ', ' Jennifer ', ' Sherry ', ' Eva ']]

Text-processing tools like awk and sed allow your to automatically perform a sequence of editing operations based on a SCRI Pt. For this problem we consider the specific case in which we want to perform a series of string replacements, within a Singl E line of text, based on a fixed set of rules. Each rule is specifies the string to find

Console.log (Array.slice (-1)); [6]
Console.log (Array.slice ( -2));//[5,6]
Console.log (Array.slice (-3));//[4,5,6]
Array truncation
This trick is primarily used to lock the size of an array, which is useful if you are deleting elements from an array. For example, your array has 10 elements, but you just want the first five elements, then you can truncate the array by array.length=5. As the following example:
var array = [1,2,3,4,5,6];
Console.log (Array.Length);
Label:The SELECT TOP clause is used to specify the number of records to return. The SELECT TOP clause is useful for large tables with thousands of records. Note: Not all database systems support the SELECT TOP clause. SQL server/ms Access Syntax SELECT TOP number|percent column_name (s) from

Anaconda, it put the above required packages are integrated together, so we actually only need to install Anaconda software on the line, and nothing else to pretend.
Second, download and install Anaconda
First to www.continuum.io/downloads download Anaconda, now the version has python2.7 version and python3.5 version, download the corresponding version, the corresponding system anaconda, it is actually a sh script file, About 280M or so.
This series takes windows7+python3.5 as an example, so we

environmentIf you also want to continue installing python2.7 virtual environments, the method is consistent with the installation of python3.6.After the installation of the above virtual environment Py27 is complete, additional Python libraries can be installed after the virtual environment has been activated.such as installing the requests librarypip install requestscan be installed successfully.If you encounter pip Ann as a failure , try the following: (install under the specified path):
Anaconda does bring a lot of convenience, but it has also relied too much on the ability of Conda to download Python packages with one click. This is not, these days suddenly to use FASTFM this package, helpless Conda not, so can only download down from GitHub, to achieve local installation.Here are the manual download and installation steps:One, download from GitHub:Select releases , you will see a series
I downloaded the Python3 first, and then because of the need for 2 to download the anaconda2, but found there is a very serious coexistence problem.Looking for a variety of online coexistence problems, found that the internet is basically based on a anaconda and then create another environment through the virtual environment, thus realizing the coexistence of two py.But this is not my intention, before looking for a lot in the method can not solve even. Now using
I was immediately silent. This is because the old implementation method (before the network method) is difficult to extend or maintain, and is not ready to enter its golden period.
I'm very satisfied with the network. Unexpected applications are often able to work properly and into projects are now ready to enter their golden period. Into projects can be obtained by Conda and Pip, independent of Blaze. It relies mainly on numpy, pandas and Networkx,
TensorFlow in a Python environment, the easiest way to do this is to use the ANACONDA3 integrated environment for installation.
First of all, download the anaconda3,3.6 version or version 2.7 of the Python version in the Anaconda3 website.
You do not need to install the Python direct install Anconda3 beforehand, will automatically install the corresponding Python.
After the Anaconda installation is successful, we need to modify its package management image as a domestic source.
In CMD, r
five elements, you can use array. length = 5 to truncate the array. For example:
var array = [1,2,3,4,5,6];console.log(array.length); // 6array.length = 3;console.log(array.length); // 3console.log(array); // [1,2,3]
Replace all
String. the replace () function allows you to use a string or regular expression to replace a string. This function only replaces the string that appears for the first time. However, you can use the/g in many regular expressions to simulate replaceAll () function:
var s
value as the value of begin, you can obtain the last element of the array. For example:
var array = [1,2,3,4,5,6];console.log(array.slice(-1)); // [6]console.log(array.slice(-2)); // [5,6]console.log(array.slice(-3)); // [4,5,6]
Array truncation
This tip is mainly used to lock the array size. It is very useful if it is used to delete some elements in the array. For example, if your array has 10 elements, but you only want to use the first five elements, you can use array. length = 5 to truncate
list, for example:
The Code is as follows:
>>> L = [[1, 2, 3],[4, 5, 6],[7, 8, 9]
Example 1: A nested list composed of a list of men and women. The list is composed of names with more than two letters e.
The Code is as follows:
Names = [['Tom ', 'Billy', 'jefferson ', 'Andrew', 'westsley ', 'steven', 'job'],['Alice ', 'jill', 'ana', 'wendy ', 'jennifer', 'sherry', 'eva ']
Implement with a for Loop:
The Code is as follows:
