python中如何将字符串转换为列表，从文本文件中读取字符串

Question

我将一些数据保存在 out.txt 文件中，并希望将它们作为列表读取以进行某些计算，我使用此代码进行读取

f = open('peer5/out12.txt', 'r')
s = f.readlines()
for line in s:
    result = line
    print result
f.close()

现在我得到的结果是

[{u'apeer': 4, u'bisSucc': 0}, {u'apeer': 3, u'bisSucc': 0}, {u'apeer': 2, u'bisSucc': 0}]

这是一个字符串，我想将它们转换为一个列表，但形式将与结果相同，然后我尝试了代码

result1 = map(list,line)和result1 = map(list,line.split(","))

但结果 1 看起来像：

[['['], ['{'], ['u'], ["'"], ['a'], ['p'], ['e'], ['e'], [ 'r'], ["'"], [':'], [' '], ['4'], [','], [' '], ['u'], ["'"] , ['b'], ['i'], ['s'], ['S'], ['u'], ['c'], ['c'], ["'"], [ ':'], [' '], ['0'], ['}'], [','], [' '], ['{'], ['u'], ["'"] ， ['一个梨']， [”'”]， ['：']， [' ']， [' 3'], [','], [' '], ['u'], ["'"], ['b'], ['i'], ['s'], ['S'] , ['u'], ['c'], ['c'], ["'"], [':'], [' '], ['0'], ['}'], [' ,'], [' '], ['{'], ['u'], ["'"], ['a'], ['p'], ['e'], ['e'] , ['r'], ["'"], [':'], [' '], ['2'], [','], [' '], ['u'], ["' "], ['b'], ['i'], ['s'], ['S'], ['u'], ['c'], ['c'], ["'"] , [':'], [' '], ['0'], ['}'], [']'], ['\\n']]

我可以将字符串转换为列表，但数据的形式不会改变吗？

Answer 1

但是，你能告诉我们一个你真正想要什么的例子吗？

例如，您有一个字典列表

[{u'apeer': 4, u'bisSucc': 0}, {u'apeer': 3, u'bisSucc': 0}, {u'apeer': 2, u'bisSucc': 0}]

每一行都是一个字典，你想把每个字典转换成一个列表吗？

[[u'apeer', u'bisSucc'], [u'apeer', u'bisSucc'], [u'apeer', u'bisSucc']]

如果是这样，您可以使用列表理解：

[list (x) for x in result]

Answer 2

例子

list = []
path = 'c:/users/-e/my documents/text.txt'

with open(path, 'r') as file:

    for line in file:
        list.append(line)

    print(list)
