python - 列出为文件，然后将该文件作为python中的列表读取

Question

我有一个从模拟生成日期的python脚本。 （Python版本2.7）
我试图将模拟数据写入文本文件，然后在另一个python脚本中打开这些文件。最后，我需要的是一个1000x200的浮动矩阵。我有以下代码用于编写文件

tradereturn = agent.trade(agentset,t,G,seller,buyer,connections,tradeprobability,buyer_contpayoff[t],seller_contpayoff[t],buyer_offer[t],seller_offer[t]) 
print(tradereturn)

gains.append(tradereturn[0]) #gains is a list that should have about 200 entries
trade.append(tradereturn[1]) #trade is a list    

在我的每1000回合中，我的〜200个长度清单被写入到增益文本中

for listitem in gains:
    gainstext.write('%s\n' % listitem)

然后，将其导入另一个脚本中，如下所示：

gains = open("gains.txt", "r")

if gains.mode == "r":
    contents = gains.readlines()
    print(contents)
    print(type(contents))
    print(len(contents))

    contents = str(contents)
    print(len(contents))

作为列表，我只得到长度为1的列表。作为字符串，它是长度为200万的字符串。它显示为一串用逗号分隔的浮点数，这是一个示例：

输出：

我希望逗号之间的每个数字都是单独的条目。我怎样才能做到这一点？

我正在使用以下python软件包：


网络
matplotlib.pyplot
麻木
科学统计
随机
熊猫作为pd

Answer 1

contents.split(',')应该用逗号分隔。由于字符串较长，因此不确定是否有更快的方法。

>>> s = '1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677'
>>> s.split(',')
['1.7130853299339677', ' 1.7130853299339677', ' 1.7130853299339677', ' 1.7130853299339677', ' 1.7130853299339677']

你也可以另存为JSON

>>> import json
>>> zz = [1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 1.7130853299339677, 0.6261130766021059, 0.7265157347076596, 0.7265157347076596, 0.7265157347076596, 0.7265157347076596, 0.7265157347076596, 0.7265157347076596, 0.7265157347076596, 0.7265157347076596, 0.7265157347076596, 0.7265157347076596, 0.7265157347076596, 1.5338201626994945]
