#5 Python tutorial for beginners | Getting Started with Python #coding

HELLO CONNECTIONS,
DESCRIPTION ?
In this lecture we will learn:
- How operations are performed in Python language?
- Different types of Arithmetic operations - What are strings?
- How strings are used in Python?
- Function in a Python
- Concatenation and Repetition of Strings - New line character and Raw string

#1
- We will learn the Python IDLE in this tutorial.
- The language that the computer understands is Binary
Code i.e, 0 and 1.
- We use a programming language to write code, which is
neither a binary language nor English. - Programming language has its own protocols and
grammar which we use.
- We will write code in a programming language say Python and then it will convert into a binary format that the computer will understand.
- We can perform several operations using Python language.
- Starting with operations like Addition, Subtraction,
Multiplication, and Division. - We do addition, subtraction and multiplication with integer values, and then it gives us answers also in integer
data type. - But when performing division with integer values then it
gives us an answer in float data type.
-Float stands for Floating Point Representation. - When we divide two integer values then it might be possible that the answer can in decimal.
e.g., 4/2 = 2.0

#2
- As the interpreter wants to give you an exact answer for the division also, it will return it in float. - If you want to get only the quotient part or the integer
part of the answer and want to neglect the decimal value,
it can be done with the help of (//).
- // (double slash) is used for division when you want to return only an integer value in the answer.
- // is also called Integer Division or Floor Division.
- We can multiple operations in a single statement as well. - We need to follow the proper syntax for the programming language.
- If we apply an operation but do not give operands, then it
will give an error. 8+9- = Error
- We can also apply BODMASS rules of mathematics to Perform operations.

#3
String is a combination of characters like "learning",
"Camera", "utkarsha", "Python", etc., all are strings.
- Whenever we use strings, we need to use double quotes(" ") or single quotes(' ') with it in python. - If you back-slash(\) to tell the python to ignore the then the quote is also treated as a simple character.
special meaning of that double and single quotes. - If you use a back-slash before a single or double quotes

#4
-Function is a set of tasks that can be done. We need to call functions. There are several functions in Python like the print() function.
- Round brackets are used with a function to pass a parameter in it.
- We can define our own functions as well.

#5
- Concatenation is used to combine two things like we can
convert two strings into one using concatenation. - Concatenation is done using the (+) operator. e.g., 'utkarsha' + 'utkarsha'
- Repetition is used to print a single value multiple times like we can print a string like "Navin" multiple times. - Repetition is done using the (*) operator. e.g., 'utkarsha' * 3

#6
-(\n) has a special meaning in Python. It is used to enter a new line.
