Video Title: Python Sets Are OP!! #python #programming #coding
All right so let’s say we have two list of integers here A and B what I want to do is merge these two lists together remove any duplicates and sort the new list in ascending order so let me create a function here called merge arrays with
Array a and array b as our inputs so remember I want to combine arrays A and B remove any duplicates and sort in ascending order so what I’m going to do is combine array a and array B just by saying array a plus array B then I’m
Going to turn this newly combin list into a set so why am I doing this well sets by Nature remove any duplicates due to the way they are stored in memory and then let’s use the built-in sorted function on this set which will take the elements of our set and create a sorted
List as an output all right so let’s just return this whole line here now down here let’s call our function so let’s say C is equal to merge arrays with a and b as inputs so let’s run this and there we go be sure to leave a like if you found this helpful

The name "merge_arrays" is misleading: I would not have guessed that it removes duplicates and sorts the result.
There’s so many things wrong with this. Please consider remaking this short.
C=A+B
print(list(set(C)))
this is O(nlogn), which is suboptimal for this problem, although I would agree that this solution is way cleaner.
I don't understand any use case for this
What there are you using? It looks so good! 🥹
okay all sorted and set to go
Training leetcode with python is practically pointless, because it has pretty much everything build in anyways
You can also iterate the list you don’t always have to turn it into a set.
merge_arrays = lambda arrayA, arrayB : sorted(set(arrayA + arrayB))
a = [1,2,3,3,4,5,6]
b = [4,4,5,6,7,8,9]
c = merge_arrays(a,b)
print(c)
Python hella cheating 😂 but i love it
Interviewer : get the hell out of my office
Great tip.
When is your full Python tutorial dropping?
…so in Python, you "sorted" an array instead of "sort"ing?
such a good language
