VARIABLE ASSIGNMENT - WE DON'T HAVE TO DECLARE THE TYPE AS OTHER LANGUAGES, WE JUST CAN ASSIGN A VALUE DIRECTLY

e.g amount = 10 type(amount) = int

amount = amount + 4

amount = 5.55 type(amount) = float

PRINT STATEMENT- print(amount)

COMMENT = #THIS IS A COMMENT

IF-ELSE - if amount < 555:

print(amount)

String : s = "devesh is a good boy"

or s = 'devesh is a good boy'

print(s*4) = devesh is a good boy devesh is a good boy devesh is a good boy devesh is a good boy

THIS IS OPERATOR OVERLOADING!

Arithmetic Operations-

a + b Addition Sum of a and b

a - b Subtraction Difference of a and b

a * b Multiplication Product of a and b

a / b True division Quotient of a and b

a // b Floor division Quotient of a and b, removing fractional parts

a % b Modulus Integer remainder after division of a by b

a ** b Exponentiation a raised to the power of b

-a Negation The negative of a
