If you have your own Python modules you want to copy, you can simply copy them and run on other systems with Python installed. If you want to copy installed modules, the best way is to install the same version of Python on the second system. Then run$ pip freeze > installed_modules.txton the first system to get a list of the installed modules in the installed_modules.txt file. Now copy this file over to second system. Now use pip to install these modules using:$ pip install -r installed_modules.txtThis will install all modules that were installed on the first system. It is ... Read More
There are ways to import Python modules remotely. It is not recommended to do so though as it will slow down your app. You can use the knockout module to achieve this. To install knockout use:$ pip install knockoutNow in order to import modules remotely, you can use knockout like:>>> from knockout import urlimport >>> urlimport.register() Url importing enabled. Add urls to sys.path.A valid url looks like this: http://example.com/path/to/repository/#packagenameThis stuff is experimental, use at your own risk. Enjoy.>>> import sys >>> sys.path.insert(0, 'http://www.crummy.com/software/BeautifulSoup/download/3.x/BeautifulSoup-3.0.8/#BeautifulSoup') >>> import BeautifulSoup ... >>> BeautifulSoup If you are not able to install modules on a machine(due ...

The best and recommended way to install Python modules is to use pip, the Python package manager. It automatically installs dependencies of the module as well.If you have Python 2 >=2.7.9 or Python 3 >=3.4 installed from python.org, you will already have pip and setup tools, but will need to upgrade to the latest version:On Linux or macOS:pip install -U pip setuptoolsOn Windows:python -m pip install -U pip setuptoolsIf you’re using a Python install on Linux that’s managed by the system package manager (e.g "yum", "apt-get" etc…), and you want to use the system package manager to install or upgrade ...

Yes you can keep Python modules in compiled format. Python automatically compiles Python source code when you import a module, so the easiest way to create a PYC file is to import it. If you have a module mymodule.py, just do:>>> import mymoduleto create a mymodule.pyc file in the same directory. A drawback is that it doesn’t only compile the module, it also executes it, which may not be what you want. (however, it does compile the entire script even if it fails to execute the script). To do this programmatically, and without executing the code, you can use the ... Read More
The HTML Window length property returns the number of elements in the current HTML document.SyntaxFollowing is the syntax −window.lengthLet us see an example of HTML Window length property −Example Live Demo body { color: #000; height: 100vh; background-color: #8BC6EC; background-image: linear-gradient(135deg, #8BC6EC 0%, #9599E2 100%); text-align: center; } .btn { background: #db133a; border: none; height: 2rem; border-radius: 2px; width: 40%; display: block; ...

This is not possible with the pip. All of the packages on PyPI have unique names. Packages often require and depend on each other, and assume the name will not change. Even if you manage to put the code on Python path, when importing a module, python searches the paths in sys.path by order and stops at first match. So whatever module it finds first, it'll stop at that. You best bet is to copy all the code from the libraries to you codebase, change the module name of either and then import it.If you're importing modules with same name from ... Read More
The HTML5 mathematical operators are used for mathematical and technical operators’ representation in an HTML document. So, to use such operators to web page, we use HTML entity name. If no entity name exists then you can use entity number which is a decimal or a hexadecimal reference.SyntaxFollowing is the syntax −&operatorName;Or&#operatorHexcode;Or&#operatorHexadecimalcode;Let us see an example of HTML5 mathematical operators −Example Live Demo body { color: #000; height: 100vh; background-color: #8BC6EC; background-image: linear-gradient(135deg, #8BC6EC 0%, #9599E2 100%); text-align: center; } ...

As stated in the official docs −KEY is normally a synonym for INDEX. The key attribute PRIMARY KEY can also be specified as just KEY when given in a column definition. This was implemented for compatibility with other database systems.Let us first create a table −mysql> create table DemoTable ( Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, Name varchar(50), Age int ); Query OK, 0 rows affected (0.69 sec)Following is the query for INDEX, which is a synonym to KEY −mysql> create index Name_Age_Index on DemoTable(Name, Age); Query OK, 0 rows affected (0.65 sec) Records: 0 Duplicates: ...
