Learn Python Advanced Part 1: ISL Interpretation Included

Have you ever wondered how a one-time password(OTP) is generated instantly? For example, a one-time password(OTP) is received whenever a payment is made. It is a random number of some predefined length and can be generated using a random library of python. Python has an in-built library for the generation of random numbers. The random library has different functions for generating random numbers in python.

Time Functions - Python provides library to read, represent and reset the time information in many ways by using “time” module. Date, time and date time are an object in Python, so whenever we do any operation on them, we actually manipulate objects not strings or timestamps. In this section we’re going to discuss the “time” module which allows us to handle various operations on time.

User Defined Functions - Functions that we define ourselves to do certain specific task are referred as user-defined functions. The way in which we define and call functions in Python are already discussed. Functions that readily come with Python are called built-in functions.

Lambda Functions - A lambda function is an anonymous function (i.e., defined without a name) that can take any number of arguments but, unlike normal functions, evaluates and returns only one expression.

Modules - A Python module is a file containing Python definitions and statements. A module can define functions, classes, and variables. A module can also include runnable code. Grouping related code into a module makes the code easier to understand and use. It also makes the code logically organized.

Files I/O In this tutorial, you'll learn about Python file operations. More specifically, opening a file, reading from it, writing into it, closing it, and various file methods that you should be aware of. Files are named locations on disk to store related information. They are used to permanently store data in a non-volatile memory

In this section, you'll learn how to handle exceptions in your Python program using try, except and finally statements with the help of examples. Python has many built-in exceptions that are raised when your program encounters an error (something in the program goes wrong). When these exceptions occur, the Python interpreter stops the current process and passes it to the calling process until it is handled. If not handled, the program will crash.
