6 BUILD SOFTWARE TO TEST SOFTWARE Advantages of using Python for automation ● general-purpose ● Interpreted ● Interactive ● object-oriented ● high-level programming language ● dynamically typed ● garbage collected

7 BUILD SOFTWARE TO TEST SOFTWARE Readability and Simplicity ● simple and concise keywords (i.e, if, else, for, while, and def convey their purpose clearly) ● utilizes whitespace indentation instead of curly brackets to indicate code blocks ● readable Data Structures: Python provides built-in data structures like lists, dictionaries, and sets that are easy to read and understand. Example of lists, list comprehension, sorting, summation, and conditional statements in just several lines of code

8 BUILD SOFTWARE TO TEST SOFTWARE Broad Range of Libraries Pandas – data manipulation BeautifulSoup, PyQuery – web scrapping NumPy, SciPy – scientific computing Selenium, Pyppeteer – web testing Paramiko – SSH automation Why use libraries: 1) abstract away the complexity of low-level tasks 2) predefined functions encapsulate complex operations 3) well-defined interfaces and reusable component

9 BUILD SOFTWARE TO TEST SOFTWARE Platform Independence ● Run on various OSs (Windows, Linux, macOS…) Integration Capabilities ● robust support for APIs and can communicate with databases, web services, and external applications ● extensibility allows to wrap functionality from C/C++ libraries or leverage Python's inter-language communication capabilities
