5  print(mylist) 

1# remove duplicate from given_list using list comprehension
2res = []
3[res.append(x) for x in given_list if x not in res]

1bad_list = ["hi", 1, 2, 2, 3, 5, "hi", "hi"]
2good_list = list(set(bad_list))

1''' we can convert the list to set and then back to list'''
2a=[1,1,2,3,4,5,6,6,7]
3'''b=(list(set(a))) # will have only unique elemenets'''

1# get unique items in list aa with order maintained (python 3.7 and up)
2list(dict.fromkeys(aa))
