# in python you can declare a variable by simply typing the variable name and assigning a value to it, no keywords needed. like so:
variable_name = 'value'
# there are 4 types of values you can store in python, just like most languages.
# a string: 'Helo word!'
# an integer: 1010001
# a float: 1010101.7
# and last, a boolean: True or False
# when you have declared a variable you can call it by simpely typing its name
print(variable_name)
# happy coding!
#to create a variable in python:
var = 15 #var is the variable name and 15 is it's value
print(var) #prints the variable var's value
var2 = var + 15 #creating a new variable and value is var + 15
print(var2) #prints var2 which would be 30
# By Codexel
#How to print a variable the code below sets a variable to Hello, World!
variable = "Hello, World!"
#Use the print function to write out anything (the name variable after the print function is the name of the variable you want to print)
print(variable)
#single name variable
name = "Your name"
#recomended naming of compound or multiple names are seperated by underscore _
some_variable_name = "Name of the the variable"
# Variables in Python are used to store some data in it and use it over and
# over again
# Variables can store Strings, Integers, Floats, Booleans
var_string = "Hello World!"
var_integer = 1234567890 # any number
var_float = 3.14159 # any number with decimal value
var_boolean = True # True or False
#creating variable in python
a = 15 #it is called integer
b = 'apple' #any word or number written in this "" is called string
c = False #True or False is called boolean
d = 2.45 #any number with point is called float
print(a)
print(b)
print(c)
print(d)
#it will print all the values
#Varibles Guide:
a = 5 #NUMBER
b = "Varibles!" #STRING
c = True #BOOLEN Hey, this is an edit, sorry for having it as true not True, caps matter.
d = False #BOOLEN Hey, this is an edit, sorry for having it as false not False, caps matter.
// no need to define variables explicitly like in java or c++
// we need to define them in __init__ method that creates, this i8s the key
// __init__ basically it's constructor
// instance variables for the current object self( which denotes your created instance)
class A:
def __init__(self,d):
self.d=d
//above automaticaaly creates an instance variable d for you class object
hence
ob=A(4)
// creates object ob with 1 instance variable d initialised to 4
ALSO NOTE:
// in python there is no distinction between pointer variable and
// normal variable we use same syntax for both unlike c++
// so how python distinguishes b/w a reference and normal var?
// by seeing what is being assigned to it on RHS
