python remove duplicates

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

  mylist = ["a", "b", "a", "c", "c"]
mylist = list(dict.fromkeys(mylist))

  print(mylist) 

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

def remove_dupiclates(list_):
	new_list = []
	for a in list_:
    	if a not in new_list:
        	new_list.append(a)
	return new_list

# HOW TO REMOVE DUPLICATES FROM A LIST:
# 1) CREATE A LIST
my_list = [1, 2, 3, 4, 5, 5, 5, 1]
# 2) CONVERT IT TO A SET AND THEN BACK INTO A LIST
my_list = list(set(my_list))
# 3) DONE! 
print(my_list) #WILL PRINT: [1, 2, 3, 4, 5]

mylist = ["a", "b", "a", "c", "c"]
mylist = list(dict.fromkeys(mylist))

mylist = ["a", "b", "b", "c", "a"]
mylist = sorted(set(mylist))
print(mylist)

list(dict.fromkeys(mylist))
