Day01-Introduction to Python

What is Programming? It is the fastest way to tell the computer what to do. E.g. A calculator. In other words, we can say that computer programming is the process of writing code to facilitate specific actions in a computer, application or software program, and instructs them on how to perform. Programming Languages: Python, C, C++, Java, Ruby etc. What is Python? It is: An interpreted language. It is dynamically typed. A case-sensitive language. Supports object-oriented programming language. Gouido Van Rossum first started working on Python in 1991. Example: ``` print("Hello World", 7) print(5) ``` Output: ``` Hello World, 7 5 ``` Features of python: Simple and easy programming language. Platform independent (means can work on any platform). An open-source language. Has big-library support. Some popular libraries are NumPy, TensorFlow, OpenCV etc. Uses of Python: It can be used in: Data Visualization to create plots and graphical representations. Helps in Data Analytics to...

Day04 - Variable and Data Types

What is Variable? Variable - is like a container that holds data. Example: a = 1234453734563455 print(a) b = "Harry" print(b) Output: 1234453734563455 "Harry" Data Type: Data types specify the type of data that can be stored inside a variable. It is required in programming to perform 'operations'. Data Types Classes Description Numeric int, float, complex holds numeric values String str holds sequence of characters Sequence list, tuple, range holds collection of items Mapping dict holds data in key-value pair form Boolean bool holds either True or False Set set, frozenset hold collection of unique items Binary bytes, bytearray, memoryview includes bytes, bytearray, and memoryview None NoneType represents the absence of a value Built-in Data Types: Numeric Data Type - int, float, complex: int - It contains positive or negative whole numbers. float - It is a real number with a floating-point representation. It is specified by a decimal point. complex - holds...

Day 03 - Day03-Comments, Escape Sequence and Print Statement

Comments: Comments can be used to explain Python code. It can be used to make the code more readable. It can also be used to prevent execution when testing code. Comments starts with a #, and Python will ignore them: print( "This is a print statement \nThis is a new line" ) print( "Hello World!!!" ) #Printing Hello World Output: This is a print statement This is a new line Hello World!!! Escape Sequence: To insert characters that are illegal in a string, use an escape character. An escape character is a backslash \ followed by the character you want to insert. Example: #using double quote print( 'This is\' a \"print statement\" and this is a new line' ) #using single quote print( 'This is\' a \"print statement\" and this is a new line' ) Output: This is' a "print statement" and this is a new line
