Day 15 : Basics of Python for DevOps Engineers

What is Python?

Python is an open-source, general-purpose, high-level, and object-oriented programming language created by Guido van Rossum. It has a vast ecosystem of libraries and frameworks, such as Django, TensorFlow, Flask, Pandas, Keras, and many more.

Windows Installation

1. Go to the Python website.

2. Download the latest version of Python.

3. Run the installer and follow the instructions.

4. Check the installation by opening a command prompt and typing.

Ubuntu Installation

   2.About different data types in Python.

   In Python, data types define the type of data that can be stored and manipulated within the programming environment. Here are the main data types in Python, along with examples:

   1. Numeric Types

   • int: Represents integers (whole numbers).

       pythonCopy codex = 5
       y = -3
     

   • float: Represents floating-point numbers (decimals).

       pythonCopy codea = 3.14
       b = -0.001
     

   • complex: Represents complex numbers, which have a real and an imaginary part.

       pythonCopy codec = 2 + 3j  # 2 is the real part, 3 is the imaginary part
     

2. Sequence Types

• str: Represents strings, which are sequences of characters.

    pythonCopy codename = "Shivani"
    greeting = 'Hello, World!'
  

• list: Represents a mutable sequence of items (can contain mixed data types).

    pythonCopy codefruits = ["apple", "banana", "cherry"]
    numbers = [1, 2, 3, 4.5]
  

• tuple: Represents an immutable sequence of items (can contain mixed data types).

    pythonCopy codepoint = (3, 4)  # A 2D point
    coordinates = (1, 2, 3)
  

3. Mapping Type

• dict: Represents a collection of key-value pairs, where keys must be unique.

    pythonCopy codestudent = {
        "name": "Shivani",
        "age": 25,
        "courses": ["Math", "Science"]
    }
  

4. Set Types

• set: Represents an unordered collection of unique items.

    pythonCopy codeunique_numbers = {1, 2, 3, 4, 5}
  

• frozenset: Similar to a set but immutable (cannot be modified).

    pythonCopy codefrozen_set = frozenset([1, 2, 3, 4])
  

5. Boolean Type

• bool: Represents boolean values, either True or False.

    pythonCopy codeis_active = True
    has_permission = False
  

6. None Type

• NoneType: Represents the absence of a value or a null value.

    pythonCopy codex = None
  

Type Conversion

You can convert between different data types using functions like:

• int(): Convert to integer

• float(): Convert to float

• str(): Convert to string

• list(): Convert to list

• tuple(): Convert to tuple

• set(): Convert to set

Examples of Type Conversion

    pythonCopy code# Convert float to int
    x = 5.7
    y = int(x)  # y is now 5

    # Convert int to str
    num = 10
    str_num = str(num)  # str_num is now "10"

    # Convert string to list
    s = "Hello"
    char_list = list(s)  # char_list is now ['H', 'e', 'l', 'l', 'o']
