Remove duplicates from a list in Python
I am going straight to the point
my_list = [1, 2, 3, 4, 4, 5, 2]
Enter fullscreen modeExit fullscreen mode
How do we remove duplicate no. or elements from the list.
Simple, we have 3 easy method.
- Using
set
my_list = [1, 2, 3, 4, 4, 5, 2]
updated_list = list(set(my_list))
print(updated_list)
#The output will be: [1, 2, 3, 4, 5]
Enter fullscreen modeExit fullscreen mode
As we know that set doesn't support duplicate, we can simply use this method to remove duplicates. Here I have type casted the list into a set and then again type casted in to list.
- Using
dict
my_list = [1, 2, 3 , 4, 4, 5, 2]
updated_list = list(dict.fromkeys(my_list))
print(mylist)
#The output will be: [1, 2, 3, 4, 5]
Enter fullscreen modeExit fullscreen mode
Well dict also doesn't support duplicates so when we convert the list to dict, so we are creating dict from the list and then converting it back to list.
- I don't know what to call this method
my_list = [1, 2, 3 , 4, 4, 5, 2]
updated_list = []
for item in my_list:
if item not in list:
updated_list.append(item)
my_list = updated_list
print(my_list)
#The output will be: [1, 2, 3, 4, 5]
Enter fullscreen modeExit fullscreen mode
So that was 3 ways to remove duplicates from a list.
