|count||returns number of occurances of a given element|
|index||first index of a given element, otherwise Exception is thrown|
Tuple can be created using following methods
>>>t=() --empty tuple >>>t=(1,2,3,1,2,3,3,3,3,33) --tuple with 10 elements >>>t=tuple("programmer") --tuple() built-in function with iterable object,string >>>t=tuple( (1,2,3,1,2,3,3,3,3,33) ) --tuple accepting another tuple
count method returns number of occurances of a given element
Tuple created with 10 elements, some elements are repeated.
counting occurance of element 1, element 1 occured 2 times
counting occurance of element 3, element 3 occured 5 times
counting occurance of element 333, element 333 occured 0 times,because 333 element doesnt exists, so returns 0
count function is used to
1.find repeated elements .
2. It is used to find presence of an element
>>>t=(1,2,3,1,2,3,3,3,3,33) >>> >>>t.count(1) 2 >>>t.count(3) 5 >>> >>>t.count(333) 0
index method returns first index of a given element, otherwise ValueError Exception is thrown
element index starts from 0 to N-1.
>>>t=(1,2,3,1,2,3,3,3,3,33) >>> >>>t.index(1) -- 1 is located in multiple positions, but first index returned, i.e 0 0 >>>t.index(33) -- 33 located in 9th position 9 >>>t.index(333) -- 333 doesnot exists in the tuple, so throws ValueError: tuple.index(x): x not in tupledifference between count & index is, element not found index throws Exception,whereas count returns 0
