To define a variable just use the operator (=):
number = 1 string= hello list = [1,2,3]
As you can see, it is not necessary to define the type of variables before using them.

TYPE OF DATA


int ->                                   Integer of arbitrary size
float     ->                            Floating point number
bool  ->                              For true or false values
complex      ->                   Complex numbers with real and imaginary part
str           ->                           Used to represent text
bytes      ->                             Used to represent bytes
list        ->                             A changeable sequence of objects
tuple       ->                         An immutable sequence of objects
set/frozenset    ->           A set of unique objects
dict            ->                       A structure that associates keys with values


One opportunity that Python offers is to make multiple assignments on the same line of code

a , b , c = 10, 20, 30

print a * b + c



Finally to add the comments just use # at the beginning of the line, or if it is necessary after the instructions


#hello python

hello # python
