Linear sear ch :-इस Search सर्च में element को एक-एक करके search किया जाता है और जहां element  मिल जाता है search complete. (Compare element one by one) Time taking      Best Case = O(1)     Average Case = O (n)      Worst Case Complexity O(n) Assume Find K = 41  Program # Linear Search in Python def linearSearch (array, n, x) : # Going through array sequencially for i in range( 0 , n): if (array[i] == x): return i return -1 array = [ 2 , 4 , 0 , 1 , 9 ] x = 1 n = len(array) result = linearSearch(array, n, x) if (result == -1 ): print ( "Element not found" ) else : print ( "Element found at index: " , result) Binary seach :-( Worked with sorted Array ) हमारे पास elements (a+b/2)  को Check किया जाता है और उसके हिसाब से Half parts  को eleminate कर दिया जाता है और आगे के Parts  को ऐसे ही तरीके से सर्च किया जाता है. Program for Binary Search by iteration a...

 Loop : The execution of a specific code may need to repeated several number of times. 1. For Loop 2. While Loop    Program 1 N  = Int (Input (" Enter any no ") For i in range (1,11 ):          c = n*i          print ( N , "*", i , " = ", C) Program 2.  i = 1 While ( i < = 10 ):          Print ( i )         i = i +1   For  While

 If Conditional Statement 1. if  2. if ..

 Python Data types 1. Number     a. Integer ( 10, 2, 29, -20  )     b. Float ( 1.9, 9.902, 15.2)     c. Complex ( 2.0 + 2.3j) 2. Sequence     1. String ( "hello yunus sir" )     2. List ( ["yunus" , 877, 125] ) - use Square      3. Tuple ( ( "yunus" , 877, 125) ) - use Parentheses 3.Boolean 4. Set ( {"james",4,5} )- no dublicate entry 5.Dictionary ( {1:'yunus',2:'Digital'} )

 Strings Are Array (examples) 1.  2.      3. 4. 5. 

 Variable :- Direct Assign value           Rules : -use only alphabets and _underscore in starting & it is case sensitive .           example:  x =  "John" , x =  'John' Casting : Specify the datatype of a variable           X = Str(3)  #it will show x contain integer Note important function - type(x)  output : <class 'int'> Cases :- Camel Case :  myVariableName =  "John"          Pascal Case :  MyVariableName =  "John"          Snake Case :  my_variable_name =  "John"     Assign Values 1.    x, y, z =  "Orange" ,  "Banana" ,  "Cherry" 2.  x = y = z =  "Orange" 3. fruits = [ "apple" ,  "banana" ,  "cherry" ]     x, y, z = fruits Global Variables : variable created outside of function.(by using Global keyword use can...

 Python  1. Algorithm :- Write easy and simple steps to solve any problem. 2. Flowchart :- To describe any problem solution using special chart or pictorial representation of any program flow.
