读取txt

hiram321

1 piece of chicken, 3
6 pieces of chicken, 14.95
21 pieces of chicken, 34.95


怎么读取这个txt才能变成下面列表套列表的形式

[["1 piece of chicken", 3], ["6 pieces of chicken", 14.95], ["21 pieces of chicken", 34.95]]

f = open('data.txt')
d = [x . strip() . split(',') for x in f if x . strip()]
f . close()
for x in d:
    x[1] = eval(x[1])
print(d)

        运行实况：

D:\00.Excise\Python>python x.py
[['1 piece of chicken', 3], ['6 pieces of chicken', 14.95], ['21 pieces of chick
en', 34.95]]

D:\00.Excise\Python>

请把楼上设为最佳，我从他那学到了eval函数，哈哈哈哈哈哈哈哈

with open("score1.txt","r") as fp:
    result=[[item1,eval(item2.strip())] for item1,item2 in [line.split(",") for line in fp.readlines()]]

eval  甚至可以用于执行windws命令行的命令。
