Tuple Built In Methods

 

Built in Methods for Tuple Class to perform certain operations

• count() : return the number of elements with specified values

 #program

 t1 = ("Techno Xpresss",28, 80.72, "Techno Xpresss", 80.72)
 print("t1 : ", t1)
 count = t1.count("Techno Xpresss")
 print("Techno Xpress presnts ", count, "times")

 count = t1.count(80)
 print("80 presnts ", count, "times")

 #output

 t1 :  ('Techno Xpresss', 28, 80.72, 'Techno Xpresss', 80.72)
 Techno Xpress presnts  2 times
 80 presnts  0 times

• index() : returns index of 1st matched  item, with the passed value

 #program

 t1 = ("Techno Xpresss",28, 80.72, "Techno Xpresss", 80.72)
 print("t1 : ", t1)
 index = t1.index("Techno Xpresss")
 print("Techno Xpresss 1st occurance is at index : ", index)

 index = t1.index(80.72)
 print("80.72 1st occurance is at index : ", index)

 #output
 
 t1 :  ('Techno Xpresss', 28, 80.72, 'Techno Xpresss', 80.72)
 Techno Xpresss 1st occurance is at index :  0
 80.72 1st occurance is at index :  2

                

index() will return ValueError if passed value is not an item in Tuple

 #program

 t1 = ("Techno Xpresss",28, 80.72, "Techno Xpresss", 80.72)
 print("t1 : ", t1)
 index = t1.index("Techno Xpresss")
 print("Techno Xpresss 1st occurance is at index : ", index)

 index = t1.index(80)
 print("80 1st occurance is at index : ", index)

 #output

 t1 :  ('Techno Xpresss', 28, 80.72, 'Techno Xpresss', 80.72)
 Techno Xpresss 1st occurance is at index :  0
 Traceback (most recent call last):

     index = t1.index(80)
