TXT format

One of the simplest and common formats for storing data is the TXT format; many IoT sensors log sensor readings with different timestamps in the simple .txt file format. Python provides built-in functions for creating, reading, and writing into TXT files. 

 We can access TXT files in Python itself without using any module; the data, in this case, is of the string type, and you will need to transform it to other types to use it. Alternatively, we can use NumPy or pandas.
