   • What is better in python, a Dictionary or Mysql?

     Generally speaking, if you want information from a database, ask the database for what you need. MySQL (and other database engines) are designed to retrieve data as efficiently as possible.

     Trying to write your own procedures for retrieving data is trying to outsmart the talented people who have already imbued MySQL with so much data processing power.

     This isn't to say it's never appropriate to load data into Python, but you should be sure that a database query isn't the right way to go first.

   • What is the Difference between Interactive and Script Mode in Python Programming?

     Python is a programming language that lets you work quickly and integrate systems more efficiently. It is a widely-used general-purpose, high-level programming language. It was designed with an emphasis on code readability, and its syntax allows programmers to express their concepts in fewer lines of code. In the Python programming language, there are two ways in which we can run our code:

     1. Interactive mode

     2. Script mode

     In this article, we’ll get to know what these modes are and how they differ from each other.

     Interactive modeInteractive etymologically means “working simultaneously and creating impact of our work on the other’s work”. Interactive mode is based on this ideology only. In the interactive mode as we enter a command and press enter, the very next step we get the output. The output of the code in the interactive mode is influenced by the last command we give. Interactive mode is very convenient for writing very short lines of code. In python it is also known as REPL which stands for Read Evaluate Print Loop. Here, the read function reads the input from the user and stores it...

     • The interactive mode is not suitable for large programs.
     • The interactive mode doesn’t save the statements. Once we make a program it is for that time itself, we cannot use it in the future. In order to use it in the future, we need to retype all the statements.
     • Editing the code written in interactive mode is a tedious task. We need to revisit all our previous commands and if still, we could not edit we need to type everything again.

     Bunch is a subclass of the Dict class and supports all the methods as dict does. In addition, it allows you to use the keys as attributes.

     b = Bunch(a=1, b=2)>>> b['b']2>>> b.b2

   Try it. However, a dictionary with a list as a key is not valid, as the list is mutable: Error: List as Dict Key. dict_obj = {["Mango","Banana"]:"Fruit", ["Blue", "Red"]:"Color"} But, a list can be used as a value. Example: List as Dictionary Value. dict_obj = {"Fruit":["Mango","Banana"], "Color":["Blue", "Red"]} Try it.
