In this post, we will learn how we can create pandas dataframe from MongoDB collection. MongoDB is a popular NoSQL database that stores data in a JSON-like format and offers a flexible and scalable solution for managing large volumes of data. When working with data stored in MongoDB, it is often necessary to analyze and […]
In the Python ecosystem, package distribution plays a crucial role in sharing and reusing code efficiently. While Python’s built-in package manager, pip, allows us to install packages effortlessly, sometimes it becomes necessary to distribute our own Python packages. In such cases, wheel files prove to be a valuable asset. A wheel file is a built

In this post, we will learn how to create a requirements.txt file for a python project. The requirements.txt file contains the list of all the packages needed to execute the Python project. It is very helpful, especially during the deployment. Using the requirement.txt file, we can automate the deployment of the project to a different

Pandas is one of the most popular Python libraries used by Data Scientists/Data Engineers for data wrangling and data analysis. Also, Pandas provide DataFrames (a table-like structure that stores data in rows and columns) to deal with structured datasets. These DataFrames are very similar to Spark’s DataFrames. However, Pandas dataframes are limited to a single
Previously, we discussed how we can create an Azure function in Java using IntelliJ IDEA IDE. In this post, we will learn how to create an Azure function in Python using VS Code (Visual Studio Code IDE). We know that Visual Studio Code is an open-source IDE that can be used to build, run and

Databricks provides a wrapper file system API named DBFS (Databricks File System) to perform any file-level operation such as read, write, move, delete, rename, etc. However, sometimes we may need to read the underlying file system objects directly without using the DBFS wrapper APIs. To do so, we can use HDFS APIs available through py4j

In the previous post, we had a brief discussion about the GridSearchCV and RandomizedSearchCV. Now, in this post, we will demonstrate that how we can use the GridSearchCV and RandomizedSearchCV methods available with the Sci-kit learn library for hyperparameter tuning in Python. We will use the sklearn built-in diabetes dataset in this demo. However, if

This post briefs how we can use the k-fold cross-validation to evaluate a Machine Learning model performance using the Scikit-learn library in Python. We know that the performance of a Machine Learning model depends on the training dataset. Also, if the training dataset has a peculiarity, the model created with that dataset will not work

The exploratory data analysis is a very important step in a Data Science project. It helps us to visualize the data and identify any hidden trends that might not be visible with summary statistics alone. So, we can use matplotlib and seaborn libraries to create stunning visuals in Python. However, the pandas.plotting module of the

We know that EDA (Exploratory Data Analysis), is the process of organizing, plotting, and summarizing the data to find trends, patterns, and outliers using statistical and visual methods. Here, we have already discussed various methods of performing EDA with their pros and cons on an underlying dataset. ECDF plot is another visual method of performing
