List Methods in Python | Set 1 (in, not in, len(), min(), max()…)
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
Python3
# Python code to demonstrate the working of# len(), min() and max()# initializing list 1lis = [2, 1, 3, 5, 4]# using len() to print length of listprint ("The length of list is : ", end="")print (len(lis))# using min() to print minimum element of listprint ("The minimum element of list is : ", end="")print (min(lis))# using max() to print maximum element of listprint ("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
Python3
# Python code to demonstrate the working of# index() and count()# initializing list 1lis = [2, 1, 3, 5, 4, 3]# using index() to print first occurrence of 3# prints 5print ("The first occurrence of 3 after 3rd position is : ", end="")print (lis.index(3, 3, 6))# using count() to count number of occurrence of 3print ("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
