🐍Day 13-Basics of Python For DevOps Engineer: Part-I

🐍What is Python?

Python is a Open source, general purpose, high level, and object-oriented programming language. It was created by Guido van Rossum. Python consists of vast libraries and various frameworks like Django, Flask, Pandas, CherryPy, and Web2Py etc.

🐍How to Install Python in Linux?

You can install Python in all operating system like Linux, Ubuntu, Windows & MacOS.

Installation of Python in Linux:

Update the package index: It's a good practice to update the package index before installing any new packages:

COPY
```
  sudo apt update #For Ubuntu/ Debian
```

Install Python: You can install Python using the package manager:

COPY

  sudo apt install python3 #For Ubuntu/Debian
  sudo yum install python3 #For CentOS/RHEL

Verify the Installation: After installation, you can verify that Python was installed successfully by running:

COPY
```
  python3 --version
```

💥Task: Installation of Python in Linux with Example.

🐍Different Data Types in Python

In Python, there are several built-in data types that are used to store different kinds of data. Here are some of the most commonly used data types along with examples:

Integer (int): Represents whole numbers without any fractional part.

COPY
```
  x = 10
  y = -5
```
Float (float): Represents real numbers with a decimal point.

COPY
```
  pi = 3.14
  temp = -20.5
```
String (str): Represents a sequence of characters enclosed within single quotes (') or double quotes (").

COPY
```
  name = 'Patrik'
  msg = "Hello, Python Learners!"
```
Boolean (bool): Represents either True or False.

COPY
```
  a = True
  b = False
```
List (list): Represents an ordered collection of items. Items can be of different data types.

COPY
```
  numbers = [1, 2, 3, 4, 5]
  fruits = ['Kiwi', 'Banana', 'Jackfruit']
```
Tuple (tuple): Similar to lists, but immutable (cannot be changed once created).

COPY
```
  thistuple = ("apple", "banana", "cherry")
```
Dictionary (dict): Represents a collection of key-value pairs. Keys are unique within a dictionary.

COPY
```
  person = {'name': 'Patrik', 'age': 23, 'city': 'New Nashik'}
```
Set (set): Represents an unordered collection of unique items. Duplicates are not allowed.

COPY
```
  unique_numbers = {1, 2, 3, 4, 5}
  vowels = {'a', 'e', 'i', 'o', 'u'}
```
NoneType (None): Represents the absence of a value or a null value.

COPY
```
  result = None
```

💥Conclusion:

In conclusion, Python is a versatile and powerful programming language known for its simplicity and readability. Its rich set of built-in data types, control structures, and extensive standard library make it suitable for a wide range of applications, from web development and data analysis to artificial intelligence and DevOps.
