Basic Fundamentals:

The basic fundamentals of Python like :

i)Tokens and their types.

ii) Comments

a)Tokens:

• A reserved word known as a tokens that can be defined as punctuator mark.
• Token is the smallest unit inside the given program.
• There are following tokens in Python:

Keywords.
Identifiers.
Literals.
Operators.

Tuples:

• Tuple is another form of collection where different type of data can be stored.
• It is similar to list where data is separated by ,(commas). Only the difference is that list               uses [] (square bracket) and truple uses ()(parenthesis).
• Tuples are enclosed in parenthesis and cannot be changed.

Eg:

tuple=('python',200,70.5,'basic')
tuple1=('fundamentals',20)

Above is a declaration of truple there are tow variable in truple truple and tuple1.

             Outputs :

• when you write in the console truple then it display all truple value.

   like :
tuple
('python',200,70.5,'basic')

• when you want a specific position data and after position all data then write a variable name and its value position and after that put a : (colon) sign 

like :
tuple[2:] (truple(name of the variable)[2(it is a position of variable):(it is like a * after                           position all data print)])
(70.5, 'basic')

• when you know the what position data you want that time use this variable name [ position of data ]

like :
   tuple1[0]
   'fundamentals'

collaboration of two truples 

• using +(plus)sign you can collaborate two or more truples.

like :
tuple+tuple1
('python',200,70.5,'basic','fundamentals',20)


Dictionary:

Dictionary is a collection which works on a key-value pair.
It works like an associated array where no two keys can be same.
Dictionaries are enclosed by {} (curly braces) and values can be retrieved by []                                    (square bracket).

Syntax :
variable name =(equal sign) {'key':(colon)'value }

Like :
Deceleration : dictionary={'name':'abc','id':500,'dept':'ec'}
Input  : dictionary
Output :{'dept': 'ec', 'name': 'abc', 'id': 500} (It display output after sorting)

Input : dictionary.keys() (if you want only keys then write a variable name .(dot) keys())
Output: ['dept', 'name', 'id']
Input : dictionary.values() (if you want only values then write a variable name .(dot) values())
Output: ['ec', 'abc', 500]

ii) Comments :

python support two types of comments.

1) single line comments :

single line comments start with # sign.

like #comments
2) Multi line Comments :

Multi lined comment can be given inside triple quotes.

like :
'''multi line
comment '''
