Python is at its peak popularity due to its easy-to-understand syntax and versatile libraries. With that in mind, using Python tools for data science isn’t surprising. Data scientists do not have an easy job. They have to understand tons of complex ideas and polish existing data in order to interpret them.
To make things easier, Python tools containing various libraries exist to deal with such tedious tasks. For instance, data scientists have to analyze a large number of data and follow through with several processes to come to their conclusion. That means a lot of repetition is undoubtedly at play here – and Python tools are handy right now.
Must-Have Python Tools For Data Science
There are too many libraries in Python to count, so one cannot expect a single Python tool to have every library squished into it. Perhaps something like that will exist in the future, but for now, let’s look at the 10 best and essential Python tools for data science.
01. NumPy
Key Specs
- Fundamental statistical and random numerical processes are included for better and more convenient data analysis.
- Carrying out bulk mathematical operations is almost instantaneous in Numpy; the heavy load doesn’t slow it down.
- It supports discrete Fourier transformations, which can be used to interpolate and clean up data.
- Exclusive matrices make it easier to do introductory linear algebra, which is crucial to data science.
- Vectorized calculations within the N-th dimension arrays make looping (in C) easier.
02. Vaex
Key Specs
- Vaex supports lazy or delayed data evaluation, meaning that it works only on the user’s command.
- It can go through a billion rows of data each second, making it the fastest Python DataFrame tool.
- Basic statistical operations such as mean, mode, summation, standard deviation, etc., are feasible.
- Can visualize large Datasets in 1D, 2D, and 3D, which helps interpret data in a much more reliable manner.
- Uses Numpy arrays to store data in columns that can be memory-mapped.
03. Scikit-Learn
Key Specs
- It’s packed with methods that enable the user to check if the results from data analysis are accurate or not.
- Has algorithms to efficiently perform lengthy mathematical operations such as Gauss-Jordan, Bayesian, Probability trees, etc.
- Uses feature extraction methods to reduce unnecessary data from visual or written datasets to help speed up data analysis processes.
- Can create discrete class labels for separating data categories, which helps in pattern recognition.
- Transformation features make it easier to manipulate data and predict future trends.
04. TensorFlow
Key Specs
- It supports visualizing graph models point-to-point and focuses on details which may help interpret data with high accuracy.
- Feature columns help vectorize and transform the data inputs to perform operations leading to desired outputs for bulk datasets.
- Can perform several statistical operations that can help with Bayesian probability models.
- Debugging real-time data from graphical models in a visualizer is easy and fast in TensorFlow.
- Layered components can help optimize numerical data analysis with initializers that help maintain gradient scale.
05. Dask
Key Specs
- Leverages NumPy and Pandas DataFrames for parallel computing when carrying out hefty tasks.
- Includes a Dask-Bag object that filters and maps data for extensive data collection.
- It runs on fast numeric algorithms through serialization and minimum runtime as well as using only memory necessary resources.
- Dask can also work in a single process instead of clusters when necessary by scaling down.
- Errors can be debugged locally in real time since the IPython kernel allows the user to investigate via a pop-up terminal that does not pause other operations.
06. Matplotlib
Key Specs
- Can generate complex subplots semantically, which helps smooth out data for better analysis.
- Data visualization is more convenient as one can customize their axes in any way they want.
- It Uses legends, ticks, and labels for better data representation and has string and lambda functions for tick formatters.
- Saving figures while working with the backend can ensure data loss prevention when integrated with Jupyter Notebook.
- It has an interface that MATLAB inspired for more straightforward data visualization and manipulation.
07. Keras
Key Specs
- Keras supports a vast amount of neural network models that help understand data even better.
- The tool comes with various deployment choices that reduce prototyping time for data models.
- One can use Keras with other libraries and tools due to its modular nature and customization support.
- It can help with pattern recognition by making predictions after evaluating a newly built model.
- As Keras has a simple network, it doesn’t often need debugging, so results are more reliable.
08. BeautifulSoup
Key Specs
- Parses web pages like a browser do, so the interface is very user-friendly.
- Fast data scraping into tree structures to make data easy to read and manipulate.
- It is also able to crawl websites, meaning it can index data as it scrapes.
- Supports Jupyter Notebook integration that allows users to store and preview data in bulk.
- The parsing feature also helps with data analyzing and identifying semantic patterns.
09. Numba
Key Specs
- The Latest Numba versions are highly memory efficient and have a GPU code reduction algorithm that compiles using necessary resources only.
- Supports CUDA accelerated codes and AMD ROCm APIs for even faster compiling.
- Can perform parallel computation for optimizing Just-In-Time compiled functions.
- Numba can also be integrated with NumPy for numerical computations with the help of NumPy arrays.
- The Boundscheck feature helps keep numerical arrays working smoothly and debug errors faster.
10. SciPy
Key Specs
- Scipy comes with advanced commands and classes that can manipulate and visualize data, sub-packages for cluster algorithms, and more.
- It can process images up to the N-th dimension, much like NumPy arrays, but more scientifically to smooth out data.
- Can perform Fourier transformations to interpolate data and weed out anomalies.
- The LAPACK package based on Fortran can compute fundamental linear problems with ease.
- Supports NumPy integration to enhance numerical calculations and do vectorized looping with accuracy.
