By adding this function it will now find and load all of the CSV file names and with each iteration of the loop, the CSV files are appended to the date frame the first iteration would be appended and then the second iteration resulting in a list of extracted data.

Assume the role of a Data Engineer and extract data from multiple file formats, transform it into specific datatypes, and then load it into a single source for analysis.

Continue with the course and test your knowledge by implementing webscraping and extracting data with APIs all with the help of multiple hands-on labs.

After completing this course you will have acquired the confidence to begin collecting large datasets from multiple sources and transform them into one primary source, or begin web scraping to gain valuable business insights all with the use of Python.

PRE-REQUISITE: Python for Data Science, AI and Development course from IBM is a pre-requisite for this project course.

Please ensure that before taking this course you have either completed the Python for Data Science, AI and Development course from IBM or have equivalent proficiency in working with Python and data.

NOTE: This course is not intended to teach you Python and does not have too much instructional content.

After watching this video, you will be able to: Define the Extract, Transform, Load process or ETL process Explain the correct order of ETL functions Write a simple ETL program Have you ever wondered how data was collected from multiple sources and combined to become a single source of information This type of data collection is called Batch processing, and today we will be exploring a type of batch processing called Extract, Transform and Load.

Extract, Transform and Load or (ETL) does exactly what the name implies.

It is the process of extracting large amounts of data from multiple sources and formats and transforming it into one specific format before loading it into a database or target file.

Some of your data is in CSV format, the other data is JSON files.

You need to Extract all this data into one file so the AI can read it.

Your data is in imperial but the AI uses metric units so you must transform it.

The AI only reads CSV data in one big file, so you need to load The data as CSV Lets implement the following ETL with Python Lets look at the extraction Step, with some simple examples.

Before we discuss the extract function, lets discuss its composite functions Lets discuss, the glob function, from the glob module.

The input is the file extension and the output is a list of files with that particular extension.

Consider the list of of.json and.csv files.

The input is the glob file extension preceded by a star and a Dot.

The output is a list of.csv files.

We can do the same for.json files.

We can write a file to extract CSV of names, height, and weight.

The input is the file name of the.csv file, the result is a data frame.

The input is the name of the.json file, the output is a data frame.

Check out the lab for more examples The Function extract will extract large amounts of data from multiple sources in batches.

The Result is an empty data frame with the column names assigned.

Lets look at the process to extract the.csv file.

We start by adding a loop to find all of the CSV files.
