# merge list
string = "I said a hib hubbit"
list = []
list.extend(string.split())

# replace with diction key values:
inch_to_mm = {
    '3/8"' : '10mm',
    '1/2"' : '12mm',
    '5/16"': '8mm',
    '1/4"' : '6mm'
}

for k, v in inch_to_mm.items():
    product_name      = product_name.replace(k, v)
    product_variation = product_variation.replace(k, v)
