List methods are discussed in this article.
1. len() :- This function returns the length of list.
List = [1, 2, 3, 1, 2, 1, 2, 3, 2, 1] print(len(List)) Output: 10
2. min() :- This function returns the minimum element of list.
List = [2.3, 4.445, 3, 5.33, 1.054, 2.5] print(min(List)) Output: 1.054
3. max() :- This function returns the maximum element of list.
List = [2.3, 4.445, 3, 5.33, 1.054, 2.5] print(max(List)) Output: 5.33
# Python code to demonstrate the working of # len(), min() and max() # initializing list 1 lis = [ 2 , 1 , 3 , 5 , 4 ]
# using len() to print length of list print ( "The length of list is : " , end = "")
print ( len (lis))
# using min() to print minimum element of list print ( "The minimum element of list is : " , end = "")
print ( min (lis))
# using max() to print maximum element of list print ( "The maximum element of list is : " , end = "")
print ( max (lis))

The length of list is : 5 The minimum element of list is : 1 The maximum element of list is : 5
Output:
The length of list is : 5 The minimum element of list is : 1 The maximum element of list is : 5
4. index(ele, beg, end) :- This function returns the index of first occurrence of element after beg and before end.
List = [1, 2, 3, 1, 2, 1, 2, 3, 2, 1] print(List.index(2)) Output: 1
5. count() :- This function counts the number of occurrences of elements in list.
List = [1, 2, 3, 1, 2, 1, 2, 3, 2, 1] print(List.count(1)) Output: 4
# Python code to demonstrate the working of # index() and count() # initializing list 1 lis = [ 2 , 1 , 3 , 5 , 4 , 3 ]
# using index() to print first occurrence of 3 # prints 5 print ( "The first occurrence of 3 after 3rd position is : " , end = "")
print (lis.index( 3 , 3 , 6 ))
# using count() to count number of occurrence of 3 print ( "The number of occurrences of 3 is : " , end = "")
print (lis.count( 3 ))

The first occurrence of 3 after 3rd position is : 5 The number of occurrences of 3 is : 2
