PYTHON PROGRAMMING FUNDAMENTALS - Coggle Diagram

- - - - literals(consonants): a fixed numeric or non numeric value is called a literal it can be number,text or other data
        strings"abc"
        numeric: integer
        floating(6.7)
        boolean(true\false)
        collection:list and tupple
        non literals absence of value (none)
      - operators: a symbol or word that performs some kind of operation and returns the result
      - identifiers:the name of any variable,constants, function or module
        
        rules for identifiers:
        FIRST LETTER CAN ONLY START WITH AN LETTER OR UNDERSCORE
        no special character is allowed except underscore
        reserve words like print cannot be used as identifiers
        space is not allowed
        upper and lowercase are treated differently
      - punctuators/delimiters : symbols which can be used as seprators of values to enclose some value (),{},[]
        exception comment symbol
      - keywords:words reserved in python with special fixed mening for the interpreter
- - - - mapping: it mapps immutable objects to mutable and ordered like dictionaries in python library
        dictionary in python holds data items in key value pairs items in a dictionary are enclosed under {}
      - sequence: a group of items with a well defined ordering where each iem is indexed by an integer
        
        strings: a sequence of characters that can be combination of letters and symbols enclosed withing
        ' ', '' '', ''' '''
        
        list: sequence of items seprated by commas and enclosed in [] can be changed
        
        tupple: sequence of items seprated by commas and enclosed {} and cannot be changed once created
        
        escape character: ussing of /,/' to treat a python character as an entity so that python just print it like any other letter
      - bool(boolean): it is a subtype of integer it represents two valued true/false eg 6>10
      - none:it is a special type of data with only a single value it is used to signify the absence of value/condition but typing (none) can make it print as a string
      - number: it stores numeric value
        
        float(floating point numbers): real numbers or floating point
        
        complex number: they are in the form of x+yj and python can tell its real and imajinary part with x as a float and y as an imajinary number
        
        int(integer): whole numbers without any fractional part
