用逗号分割字符串列表

我想转换

['60,78', '70,77', '80,74', '90,75', '100,74', '110,75']

in to

['60', '78', '70', '77'.. etc]

我以为我可以用

for word in lines:
    word = word.split(",")
    newlist.append(word)
return newlist

但这会产生这样的结果：

[['60', '78'], ['70', '77'], ['80', '74'], ['90', '75'], ['100', '74'], ['110', '75']]

有人可以提供解决方案吗？

你需要使用list.extend代替list.append.

newlist = []
for word in lines:
    word = word.split(",")
    newlist.extend(word)  # <----
return newlist

或者，使用列表理解:

>>> 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']
