Using slice and get rid of the middle two numbers

Question

This time I want to get the following result by using slice. However, I could not manage it. Is there a negative version of List[2:4] in this scenario?

Input:
List=[1,2,3,4,5,6,7]

Output:
List =[1,2,5,6,7]

Edited: By negative I mean that the I want this: List =[1,2,5,6,7] instead of this: List=[3,4]. I saw the answers and they work. Thank you very much but is there way to get the result by doing slicing?

Ps: I am not able to give votes due to my low level. Thank you for your understanding.

Answer 1

First off List[3:5] = [4, 5] so the "negative" version would be [1, 2, 3, 6, 7]. You can produce that with:

List[:3] + List[5:]

Answer 2

List[:3] + List[5:]

Hopefully that's not the real name of the variable ?

Answer 3

You can use del to remove part of a list specified by a slice:

xs = [1, 2, 3, 4, 5, 6, 7]
  
del xs[2:4]

print(xs)
# [1, 2, 5, 6, 7]
