PIP is a package management system used to install and manage software packages written in Python programming language. If you have installed the Python on Windows, and you want to use it with Python, then follow these steps to install PIP on Windows 10: Steps to Install PIP on Windows 10. First, download PIP from the following link get-pip.py.

I enjoy studying other people’s development environments. They give me plenty of insights into their aesthetic choices and their productivity shortcuts. But I have seen a lot of horrible environments cobbled together by flaky batch files that are one update away from blowing up, often leaving no option but to reinstall everything from scratch. Unfortunately, they have all been Windows environments.

Recently, I tried to install Python and pip on a Windows laptop. Though I have installed Python on Windows XP and Windows Servers for several years till 2010; there have been a lot of changes both in the Windows world such as Powershell and the Python world. So there is a lot of confusing information out there for the Python beginner. And then there is Python 3. Sigh!

Suffice to say I wanted to share what I learnt in a video aimed at the Python beginner or anyone struggling to install Python on Windows. The video and the high-level transcript follows:

What is covered?

• Installing Python 2 or Python 3 on Windows 7
• Installing pip from PowerShell
• Setting up a virtualenv
• Installing via pip

How to install Python / Pip on Windows 7 (or 8)

1. Download the MSI installer from http://www.python.org/download/. Select 32 bit or 64 bit based on the System Settings which opens by pressing Win+Break

2. Run the installer. Be sure to check the option to add Python to your PATH while installing.

3. Open PowerShell as admin by right clicking on the PowerShell icon and selecting ‘Run as Admin’

4. To solve permission issues, run the following command:

5. Enter the following commands in PowerShell to download the bootstrap scripts for easy_install and pip:

   Once these commands run successfully, you can delete the scripts get-pip.py and distribute_setup.py

   HTTP Issue with distribute_setup.py?

   [Updated 2015-03-05] The script distribute_setup is no longer available at its old location. Thanks to Rudhra for sharing the new location.

6. Now typing easy_install or pip should work. If it doesn’t it means the Scripts folder is not in your path. Run the next command in that case (Note that this command must be run only once or your PATH will get longer and longer). Make sure to replace c:Python33Scripts with the correct location of your Python installation:

   Close and reopen PowerShell after running this command.

7. To create a Virtual Environment, use the following commands:

   That’s it! I suppose the same steps work for Windows 8 as well. But I don’t have a machine to try it out. Do let me know if this worked for you.

This shows you how to install the cx_Oracle library for Python 2.7 on Fedora Linux. If Fedora has it on the server you can download it with the following yum command:

Currently, you’ll get the following failure because it’s not available in the Fedora repository:

You can download the cx_Oracle library from the Python web site. The cx_Oracle documentation qualifies module interfaces, objects, and connections. Assuming your Linux user’s name is student, you download the cx_Oracle library into the /home/student/Downloads directory. Then, you use the su or sudo command to become the root user.

As the root user, run the following yum command:

You should see the following output:

After you install the cx_Oracle-5.2.1-1.x86_64 package, you can find the installed files with this rpm command:

It lists:

After you installed the software, you can test whether inside Python’s IDLE environment with the import command, like this:

This error indicates that Oracle Client software isn’t installed, which is true in this case. I only installed the Oracle Database 11g Express Edition. You need to download the Oracle Client software and install it as the root user.

You download the Oracle Client software from the Oracle web site. Assuming your Linux user’s name is student, you download the cx_Oracle library into the /home/student/Downloads directory. Then, you use the su or sudo command to become the root user.

As the root user, run the following yum command:

You should see the following output:

You can create a Python program that checks your ability to connect to the Oracle database, like the following oracleConnection.py file:

You can run this from the Linux command line with the following syntax:

It should return the following string:

Cx Oracle Connection

Now, you can create a Python program that reads data from the Oracle database. The following oracleString.py file reads a string literal from the pseudo table dual:

You can run this from the Linux command line with the following syntax:

It should return the following string:

Low pressure could work in exactly the same way – with one major difference – the lower velocity of the air resulted in less overspray and less wasted paint.True HVLP originators such as Sicmo (Monaco) and Apollo (England) built the first professionally used low pressure sprayguns. In fact, until the late 1980’s all other HVLP sprayguns copied these early guns in every respect. Apollo was instrumental in demonstrating to SCAQMD, (South Coast Air Quality Management District – California) the greatly decreased overspray/waste aspect of High Volume/Low Pressure systems.Sicmo was also the first maker of a true HVLP conversion spraygun. Apollosprayers started in England in 1966 and then later in 1981 became the first HVLP spray equipment manufacturer in North America. The Sicmo spraygun (under different names) is still in use today with no significant changes in decades. Apollo hvlp spray gun parts.

Now, you can create a Python program that reads actual table data from the Oracle database (assuming you have a copy of my video store database). The following oracleTable.py file reads a string literal from the pseudo table dual:

You can run this from the Linux command line with the following syntax:

It should return the following strings (only a subset of the returned values):

As always, I hope this helps others who want to work with Python and the Oracle database.
