      Accessing a Character from a String

  Characters in a string can be accessed using the standard [ ] 

  k="test"
  print(k[0])
  print(k[1])
  print(k[2])
  print(k[3])

    


    
Output
  t
  e
  s
  t
    

        



 






    
Python allows negative indexing for its sequences

    
 
      k="test"
      print(k[-1])
      print(k[-2])
      print(k[-3])
      print(k[-4])

    


    
Output
      t
      s
      e
      t
    

        



 






    
String Concatenation

    
 
      k="python "
j="programming "
l="for "
m="beginners"
print(k+j+l+m)

    


    
Output
      python programming for beginners
    

        



 






    
String Repetition

    
 
      k="test"
print(k*3)
    


    
Output
      testtesttest
    

        



 






    
String Membership Test

    
 
      k="test"
print("t" in k)
Output
True
k="test this"
print("this" in k)
    


    
Output
      True
    

        



 






    
Membership Test Exercise 2

    
 
      k="test this"
print("thus" not in k)
    

    
Output
      True
    

        



 






    
String Slicing

    
 
      k="testing"
print(k[1:])
print(k[1:4])
print(k[:])
print(k[0:100])
    


    
Output
      esting
      est
      testing
      testing
    

        



 






    
String Slices - Negative Indexing

    
 
      k="testing"
      print(k[:-1])
      print(k[-3:])
      print(k[-5:6])
    


    
Output
