.strip() on array using for loop in Python not working?

I’m trying to get rid of blankspace before and after an element in an array using .strip(), How do i get this to work correctly, I currently have :

ing1 = ['Nivea', 'Water,   GlyCerin, Caprylic/Capric Triglyceride, Squalane, Coco-Caprylate/ Caprate']

    ing1list = []
    for ele in ing1[1:]:
        ing1list.extend(ele.strip().lower().split(','))
    print(ing1list)

my output which is nearly right, but still has a space before the second element is:

['water', '     glycerin', ' caprylic/capric triglyceride', ' squalane', ' coco-caprylate/ caprate']

Answer

I believe you are stripping before splitting. You want to split before stripping.

ing1 = ['Nivea', 'Water,   GlyCerin, Caprylic/Capric Triglyceride, Squalane, Coco-Caprylate/ Caprate']

ing1list = []

for ele in ing1[1:]:
    sub_ele = ele.split(",")
    for ele2 in sub_ele:
        ing1list.append(ele2.strip().lower()) 

print(ing1list)

Output:

['nivea', 'water', 'glycerin', 'caprylic/capric triglyceride', 'squalane', 'coco-caprylate/ caprate']

Also, ing1 could probably be a string.
