This is the code repository forHands-On Data Preprocessing in Python, published by Packt. Learn how to effectively prepare data for successful data analytics What is this book about? Data preprocessing is the first step in data visualization, data analytics, and machine learning, where data is ...
Let's start with concatenating multiple text files. Should you have a number of text files in a single directory you need concatenated into a single file, this Python code will do so. First we get a list of all the txt files in the path; then we read in each file and write out its...
