您需要使用
list.extend而不是
list.append。
newlist = []for word in lines: word = word.split(",") newlist.extend(word) # <----return newlist或者，使用列表推导：
>>> lst = ['60,78', '70,77', '80,74', '90,75', '100,74', '110,75']>>> [x for xs in lst for x in xs.split(',')]['60', '78', '70', '77', '80', '74', '90', '75', '100', '74', '110', '75']
