slice every n element in lists pandas code example

Example 1: python extract every nth value from list

# Basic syntax:
new_list = your_list[start_index::spacing]

# Example usage using list slicing:
# Say you have the following list and want every third item
your_list = [0,1,2,3,4,5,6,7,8,9]
new_list = your_list[0::3]

print(new_list)
--> [0, 3, 6, 9]

Example 2: split list on every nth element python

def chunks(list_in, n):
    # For item i in a range that is a length of l,
    for i in range(0, len(list_in), n):
        # Create an index range for l of n items:
        yield list_in[i:i+n]
# then just do this to get your output
list(chunks(our_list, cut_every))
