PermalinkWhat is Python?
Python is an 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, Tensorflow, Flask, Pandas, Keras etc.
How to Install Python?
You can install Python in your System whether it is Windows, MacOS, ubuntu, centos etc. Below are the links for the installation:
Ubuntu: apt-get install python3.6
PermalinkTask 1: Install Python in your respective OS, and check the version.
[root@ip-172-31-1-21 ec2-user]# yum install python
[root@ip-172-31-1-21 ec2-user]# python --version
PermalinkTask 2: Read about different Data Types in Python.
Numeric Data Types: Python supports several numeric data types, including integers (
int
), floating-point numbers (float
), and complex numbers (complex
). Integers represent whole numbers, floats handle decimal numbers, and complex numbers involve both real and imaginary parts.\# Numeric Examples integer_number = 42 float_number = 3.14 complex_number = 2 + 3j
Sequence Types: Python provides different sequence types, namely strings (
str
), lists (list
), and tuples (tuple
). Strings are used for text, lists are mutable sequences, and tuples are immutable sequences.# Sequence Examples text_string = "Hello, Python!" number_list = [1, 2, 3, 4, 5] immutable_tuple = (10, 20, 30)
Boolean Type: The Boolean data type (
bool
) is used to represent truth values, eitherTrue
orFalse
. Booleans are fundamental for conditional statements and logical operations.# Boolean Example is_python_fun = True
Set Types: Python supports sets (
set
), an unordered collection of unique elements. Sets are useful for mathematical operations like union, intersection, and difference.# Set Example unique_numbers = {1, 2, 3, 4, 5}
Mapping Type: Dictionaries (
dict
) are used to store key-value pairs, providing a mapping between keys and values. They are mutable and versatile for various data manipulation tasks.# Dictionary Example student_info = {'name': 'Alice', 'age': 25, 'grade': 'A'}
None Type: The
None
type represents the absence of a value or a null value. It is commonly used to initialize variables or as a placeholder.# None Example empty_variable = None
Special Types: In addition to the common data types mentioned above, Python has several special types like
bytes
,bytearray
, andmemoryview
for handling binary data and memory views.# Special Types Example byte_data = b'BinaryData'

Conclusion:
In conclusion, a solid understanding of Python's diverse set of data types is fundamental for any programmer aiming to harness the full power of the language. Python's versatility lies not only in its readability and simplicity but also in its ability to handle various data structures seamlessly.
