Print statement and varriable and its data types

Print statement:

In this blog i am gonna talking about print statement.
So what is print statement. Print is just a function that helps to print any kind of data 
examples :
  •  print("hello world")
  •  print(12)
  •  print ("var")
  •  print (12.5)
        So these are some examples of print statement. if you notice i use 
" " because this symbol tells that it is a string you don' worry about that i will tell you that what is a string what is an integer, what is a float what is list and etc....

variables:

  what is variables. if we try to understand variables are just box that use to different type of values as you seen above to create a variable 
you just have to type variablname =  value which you want to store
exp :
  • a = 1
  • b =1.5
  • c = "students"
so as you know how to create variable which can be used to store a value there are some condition which i given below :- 

  • A variable name must start with a letter or the underscore character
  •  A variable name cannot start with a number 
  •  A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ )
  •  Variable names are case-sensitive (age, Age and AGE are three different variables)
these are some condition let me give you an example of every condition
1, A variable name must start with a letter or the underscore character.

1 . exp -: name = "coadingfighter"   here "n" is an  alphabet,  _name = 3 here the line i have used is known as an underscore.
name = "coadingfighter"

Name = "coadingfighter"

_name = "coadingfighter"

_Name = "coadingfighter"

2 . exp A variable name cannot start with a number 
            1name = "coadingfighter"(false)

a variable only start with alphoabets and underscore like given above

3. exp A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ )

a ="value"

_a = "value"

a_ = "value"

a_1 = "value"

a1= "value"

_a1 = "value"

a1_ = "value"

a_1_a = "value"

these alphabets can be capital and you can use how many you want  like 1,2,3,10000 there is no limit alphabets to create a variable you can use same alphabets continusely 
like : aa ,aab, aabb,
and 4th condition u will learn automatically after writing basic programs. in next post i will discuss about data types thanku
