In other words, it does not focus on any particular software but teaches the general principles of data visualization with enlightening examples. Spyder is suitable for scientific programming in Python, as well as for data science and machine learning. Optical Character Recognition is the conversion of 2-Dimensional text data into a form of machine-encoded text by the use of an electronic or mechanical device. The 2-Dimensional text data can be obtained from various sources such as scanned documents like PDF files, images with text data in formats such as .png or .jpeg, signposts like traffic posts, or any other images with any form of textual data. There are many different ‘flavours’ of SQL, like SQL Server, PostgreSQL, Oracle, MySQL and SQLite. ), However, being able to complete these exercises did not sufficiently prepare me as an analyst.
