What is python set() method
Using set()
property of Python, we can easily check for the unique values.
Insert the values of the list in a set.
Set only stores a value once even if it is inserted more then once.
After inserting all the values in the set by list_set=set(list1)
, convert this set to a list to print it.
# Python program to check if two
# to get unique values from list
# using set
# function to get unique values
def unique(list1):
# insert the list to the set
list_set = set(list1)
# convert the set to the list
unique_list = (list(list_set))
for x in unique_list:
print x,
# driver code
list1 = [10, 20, 10, 30, 40, 40]
print("the unique values from 1st list is")
unique(list1)
# the unique values from 1st list is
# 40 10 20 30
list2 =[1, 2, 1, 1, 3, 4, 3, 3, 5]
print("\nthe unique values from 2nd list is")
unique(list2)
# the unique values from 1st list is
# 1 2 3 4 5
