Q:

remove duplicates from a list of lists python

# remove duplicate from given_list using list comprehension
res = []
[res.append(x) for x in given_list if x not in res]
8

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

  print(mylist) 
2
bad_list = ["hi", 1, 2, 2, 3, 5, "hi", "hi"]
good_list = list(set(bad_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", "b", "c", "a"]
mylist = sorted(set(mylist))
print(mylist)

list(dict.fromkeys(mylist))

# Python 3 code to demonstrate  
# removing duplicated from list  
# using naive methods  
  
# initializing list 
test_list = [1, 3, 5, 6, 3, 5, 6, 1] 
print ("The original list is : " +  str(test_list)) 
  
# using naive method 
# to remove duplicated  
# from list  
res = [] 
for i in test_list: 
    if i not in res: 
        res.append(i) 
  
# printing list after removal  
print ("The list after removing duplicates : " + str(res))

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