Comments and operators in python.

-

  1.  Comments - It is type of logical notes which are not a part of of a code.
There are two types of comments -

  •      Single line comment - It is started with a symbol (#).  Example - # This is a comment.
Multi- line comments -   It is started by s triple quotes ("'......"').

2. Uses of comments -
  • It increases the readability of a code.
  • Re- using existing code.
Understanding code after long term use.

3. Operators- It is a particular symbol which is used to perform some operations with the help of operands.
Operands - A kind of data types used for calculations. It always exists with python operators.
  🔥 Operators may be unary, Binary, Ternary.
  • Operators with one operands is unary operator.  Example- ++a
  • Operators with two operand is called binary operators. Example- a+b
Operators with three operands is called ternary operators. Example a<b and a>b.
4. Classification of operators:-


a. Arithmetic operators :-  +, -, * , % .
b. Relational operators :-  == , != , < , >.
c. Logical operators :- not , and , or.
d. Assignment operators :- = , +=, -=, *=,,  etc .

  • And- yeh result ko true or false me answer karta hai. Jab koi operation k left aur right side true hota hai tabhi yeh true answer me batata hai varna false batata hai answer me
.O r- jab bhi koi bhi Operation ke right ya left side me agar true aa jata hai toh yeh true answer krta hai nhi toh false .
🔥And ya or me YHI aantar hai ki jab and true uss waqt deta hai jab dono side true ho . Aur or true us waqt deta hai jab ekk side bhi true aa  jate toh.

Classification of organic compounds. (1). Acyclic or open chain compound :- These compounds contain open chain of carbon atoms in ther molecules. The carbon chains may be either stright chains or branched chains. They are also called aliphatic compounds . (2). Cyclic or close chain or ring structure :- These compounds contain chains or ring structure of atoms in their molecules. Alicyclic compounds:- These compounds contain a ring of three or more carbon atom in them. They resemble aliphatic compounds in many of their properties. AROMATIC COMPOUNDS:- These have a cyclic system containing at least one benzene ring. The parent member of the family is called benzene. Benzene has a homocyclic hexagonal ring of six carbon atoms with three double bonds in the alternate position. These compounds are also called benzonoid compounds and they exhibit special property known as aromaticity. Bicyclic and tricyclic compounds also belongs to this category. In addition to these there are some compound...
