python data type

  1. Numeric
  • int
  • float
  • complex number
  1. sequence
  • string
  • list
  • tuples
  1. Dictionary
  2. Boolean
  3. set

Numeric

     int = 12
     float = 12.6
     complex number = 12 + 12i

sequence

string : A string is a sequence of characters that is enclosed is either a single or double quotes.
      name = " ibrahim rifat"

List : list are a sequence of one or more different or similar type . They are essentially an array and hold any type inside square brackets. Each item can be accessed by its index.

      list = [1,'hello',4.5,"A"]

Tupple : Tupple are similar to lists in many ways. They contain an ordered sequence of one of more types, but main defference is that they are immutable. They cannot be modified or changed.

exampleTupple = (1,'hello', 4.5,"A")
   print(exampleTupple[1])

Dictionary

Dictionary store data in a key value object structure. Each vlaue can be accessed by directly by it's key.

Dictionary can also store any data type.

      ed = {'a':22, 'b':44.4}
      ed[a]

#output: 22

Boolean

true || false

Data type

string

          name= 'ibrahim'
          print(len(name)
          #output
          =  7
           a='hello'
          b="hello"
          #backslash has the effect of joining
           b ='sorry I wish to interrupt you there' \
              ' In addition that'
               
          a= 'you are right however'
          b=' I don't fully endorse your statement'
         
          print(a+b)   #concatenation
          =>  you are right however I don't fully endorse your statement
           
          # take input from user
          a= 'you are right however'
          b= input('enter your line : ') # or b= input()
          print(a+b)

convert

    # this function can be used to convert the provide vlaue 

    int('75')
    75
    str(55)
    '55'
    int_x = 10
    float(int_x)

#output : 10.0

function create

            def greating(person)
               print("welcom" + person)
               
          greating(ibrahim)
          #output :  welcome ibrahim

Type casting

      int(), float(),str()
      1. ord() = which returns an integer representing the underlying unicode character
      2. hex() = int to hexadecimal string
      3. oct() = returns a string representing an oct to number.
      4. tuple()  
      5. set() 
      6. list()
      7. dict()

sep funtion

               print('ibrahim','rifat') => ibrahimrifat
               print('ibrahim','rifat',sep=', ') => ibrahim rifat

direct formating

           a=12
           b=5
           ans=a+b
           print('Addition the value of {} and {}= {}'.format(a, b, ans))

output formating

                   print('I like  {0} more than {1} '.format("oranges", "grapes"))
                   print('I like  {1} more than {0} '.format("oranges", "grapes"))

               str2=input('enter your second name : ')

               print('hello {} {}'.format(str1, str2))

Note: The order of elements in the output of sets is not guaranteed to be sorted or in the same order as they were initially declared. Sets are unordered collections, and their order may vary from one execution to another.
