python list unique values code example

Example 1: python list of random values

# To create a list of random integer values:
import random
randomlist = random.sample(range(10, 30), 5)
# Output:
# [16, 19, 13, 18, 15]

# To create a list of random float numbers:
import numpy
random_float_array = numpy.random.uniform(75.5, 125.5, 2)
# Output:
# [107.50697835, 123.84889979]

Example 2: find all unique items in dictionary value python

L = [{"V":"S001"}, {"V": "S002"}, {"VI": "S001"}, {"VI": "S005"}, {"VII":"S005"}, {"V":"S009"},{"VIII":"S007"}]
print("Original List: ",L)
u_value = set( val for dic in L for val in dic.values())
print("Unique Values: ",u_value)

Example 3: python list with only unique values

my_list = list(set(my_list))

Example 4: unique list values python ordered

def get_unique(seq):
    seen = set()
    seen_add = seen.add
    return [x for x in seq if not (x in seen or seen_add(x))]

Example 5: how to find unique values in list in python

mylist = ['nowplaying', 'PBS', 'PBS', 'nowplaying', 'job', 'debate', 'thenandnow']
myset = set(mylist)
print(myset)
