Python Pro Tip: Want to use R/Java/C or Any Language in Python?

<br>

Python provides a basic and simple way to handle such requirements where we have to switch to and fro between multiple languages

Python is great. Really great.

But the field is getting/will get language agnostic with time. And a lot of great work is being done in many other languages.

While I still treat Python as a primary language, I never hesitate to move to a different language if it gets the work done.

The fact is that every language has evolved in such a way that it has built its stronghold in certain areas. For example, Some people may find it easier to use R for regression, or Plot in R using ggplot(Though I sincerely feel Python has come a long way in the visualization department.)

Sometimes it is because a particular library is written in Java/C and someone hasn’t yet ported it to Python.

But is there a better way to handle this constant nuisance?

I like Python because I understand it well now. It is easy for me to do so many things in Python as compared to doing it in R or Java or Scala.

Why do I have to code my data preparation steps in R if I just want to use the Linear Regression package in R?

Or why do I have to learn to create charts in Java if I only want to use the Stacknet package?

Now Python and R have many wrappers. How can I use R in Python or How I can use Python in R? rpy2 and reticulate

These packages are all well and good, and they may solve some problems.*** But they don’t address the generic problem. Every time I want to switch from one language to another I need to learn a whole new package/library. Not scalable at all.***

In this series of posts named Python Shorts, I will explain some simple constructs provided by Python, some essential tips and some use cases I come up with regularly in my Data Science work.

This post is about utilizing a particular package/library from another language, while not leaving the comfort of coding in our primary language.

The Problem Statement

I will start with a problem statement to explain this. Let’s say I had to create a graph using R, but I wanted to prepare my data in Python.

It is a generic problem any data scientist can potentially face. Do something in one language and then move to another language to do some other thing.

Can I do this without leaving my Jupyter notebook? Or my Python Script?

The Solution

Here is how I could accomplish this. It might seem hacky to some but I love hacks.

import pandas as pd
data=pd.read_csv("data.csv")
data = preprocess(data)
data.to_csv("data.csv",index=None)
os.system("Rscript create_visualization.R")

The <strong><em>os.system</em></strong> command provides me with a way to access my shell using Python. And the shell is a potent tool at your disposal. You can run almost any language on the shell.

The corresponding Rscript that will run in python would look something like:

data<-read.table("data.csv")
ggplot(...)
ggsave("plot.png")

I can then maybe load the png file and show it in my Jupyter notebook using something like a markdown hack.

![alt text](plot.png "Title")

For R users, who don’t want to leave the comfort of R, R also has a systemcommand analogous to os.system that you can use to run Python code in R.

Conclusion

<strong><em>os.system</em></strong>*** in Python provides us a way to do each and everything in Python by letting us call shell commands from Python.***

I have used it in plenty of my projects where I have used this concept to send e-mails using Mutt. Or to run some Java program or to fiddle around.

It seems like a hacky way, but it works and is generalized enough that you don’t have to learn a new library anytime you want to do something with any other language and get it integrated with Python.

Learn Hands-On Python Programming By Creating Projects, GUIs and Graphics

Python is a dynamic modern object -oriented programming language
It is easy to learn and can be used to do a lot of things both big and small
Python is what is referred to as a high level language
Python is used in the industry for things like embedded software, web development, desktop applications, and even mobile apps!
SQL-Lite allows your applications to become even more powerful by storing, retrieving, and filtering through large data sets easily
If you want to learn to code, Python GUIs are the best way to start!

I designed this programming course to be easily understood by absolute beginners and young people. We start with basic Python programming concepts. Reinforce the same by developing Project and GUIs.

Why Python?

The Python coding language integrates well with other platforms – and runs on virtually all modern devices. If you’re new to coding, you can easily learn the basics in this fast and powerful coding environment. If you have experience with other computer languages, you’ll find Python simple and straightforward. This OSI-approved open-source language allows free use and distribution – even commercial distribution.

When and how do I start a career as a Python programmer?

In an independent third party survey, it has been revealed that the Python programming language is currently the most popular language for data scientists worldwide. This claim is substantiated by the Institute of Electrical and Electronic Engineers, which tracks programming languages by popularity. According to them, Python is the second most popular programming language this year for development on the web after Java.
