How to Run Python Code in NotePad++


Can you run the python code from NotePad++ ?? Question seems to be little odd but we can tweak our notepad++ settings and configure it that way. Let's see how -



1. Write few line as your python code, You can use below lines-

print("Today we are going to learn how to use notepad++ to run the python code")
print("As first step, we have to write few python code line")

input("Press Enter to Exit..........")




2. Save this file, in my case, it is saved as "npp_run.py"
3. Check the python executable path in your system. In my case it is - C:\tools\Anaconda3\python.exe  (It can be different as per your python installation)

4. Now go to Run menu or Press F5. This will open a run window as below -

5. Python below code in 'the program to run' -
Python_Executable_Path $(FULL_CURRENT_PATH)
C:\tools\Anaconda3\python.exe $(FULL_CURRENT_PATH)



6. Save this Run configuration by clicking on Save button on same window

7. Choose Run button combination (can use Ctrl + Alt + Shift + Key) and Save.

8. You can see this combination under Run Menu.


9. Now, You can run the Python code by pressing the combination buttons (My case - F9)




Things to Remember:
1. This tweak is not replacement for Python IDE :-) such as PyCharm, Spider or many others.
2. Always put the  input("Press Enter to Exit..........")at very last line of your code else you will not able to see the python code output.

Learning Numpy #2

Thursday, 12 January 2017

Learning Numpy #1


Numpy is a python library used for numerical calculations and this is better performant than pure python. In this notebook, I have shared some basics of Numpy and will share more in next few posts. I hope you find these useful.

Python, IPython, Jupyter notebook, Graphlab Installation on Windows


In "Python Installation from Source in Linux" and "Data Science Tools Installation in Linux" we have seen, how to install these tools on linux, Today we will learn how to setup these tools on Windows -




Python Installation:

1. Download the Python Windows installer from here -> https://www.python.org/downloads/release/python-2711/

2. Install it as we install any software on windows

3. Now, setup the Environment Variable -
a.              If you haven’t played with environment variables before, just stick to following these instructions as you can set them up through the Windows GUI.
b.             Right click on "My Computer", select "Properties" > "Advanced system settings" and click on the "Environment Variables" button
c.             In the System Variables box, find the variable called "path" and click on the "Edit…" button
d.             In the "Variable value" box, at the end of the entry, add the following text: ;C:\Python27;C:\Python27\Scripts (change the path as per your installation)
e.             Click "OK" a couple of times and hey presto, your environment variables are set up.
f.              Open cmd and type command 'python', if you get the python prompt we are good else check the steps once again.

4. The next step in the process is to set up easy_install and so we need to go to the setuptools page (links to version 0.8) and download the ez_setup.py script. You can download it from here -> https://bitbucket.org/pypa/setuptools/raw/0.8/ez_setup.py. and put this in python script directory (C:\Python27\Scripts)

5. Open a command prompt and type python ez_setup.py install – you’ll see a load of code whizz by which will hopefully end as follows;

C:\Python27> python ez_setup.py install
Processing dependencies for setuptools==0.8
Finished processing dependencies for setuptools==0.8
C:\Python27>
6. easy_install has now been set up and you can test to see if it is there, by typing easy_install in to a command prompt, which will throw an error about no URLs, you know that the tool has been set up successfully.

To use easy_install to get new libraries, just use the following syntax: easy_install <library name>


IPython Installation:

C:\Python27> easy_install ipython
Jupyter notebook Installation
C:\Python27\Scripts> pip install jupyter
You can run the jupyter notebook as below -

C:\Python27\Scripts>jupyter notebook

Graphlab Create Installation

C:\Python27\Scripts> pip install --upgrade --no-cache-dir https://pypi.python.org/packages/source/G/GraphLab-Create/GraphLab-Create-1.7.1.tar.gz#md5=caa4b1f78625a278dd016400d15bc5bd
