I want to remove n
elements after each element in a list.
Example with n = 7
:
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17] # unmodified list
[1, 9, 17] # final list
I tried this approach but it failed, removing every alternate element from the list for some reason.
# cases is a list with over 600 numbers
case_count = 0
case_index = 0
for case in cases:
print(case_count)
print(case_index)
if case_count != 7:
popped = cases.pop(case_index)
print(case_index)
case_count = 1
else:
print("Case count equal to 7")
case_count = 0
case_index = 1

So, basically you want to slice every eighth element?
l = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17]
l[0::8]
output: [1, 9, 17]

n = 7
[arr[i] for i in range(0, len(arr), n 1)]
# [1, 9, 17]
