Question

相对简单的问题，我有这个市场数据http://pastebin.com/HmiMbux5

格式为[['data'，high，open，low，close，volume等]，['data'，high，open，low，close，volume等]]

但是，当将.txt文件保存为.csv并加载到excel时，它会将所有数据放在顶行。

我可以使用什么python代码来获取[数据]，[数据]并妥善保存它，因为[数据]，[数据]用逗号分隔，它本来与excel兼容，错了。

感谢任何帮助。

Answer 1

清理像这样的东西

sed 's/\]\,\[/\n/g' HmiMbux5.txt | tr -d "[]" >  HmiMbux5.csv

这是一个读取文件的脚本，并将其写入磁盘上的另一个文件。只有这次是正确的CSV格式。我试着在代码中解释我的步骤，所以我希望它很清楚。

file = open("HmiMbux5.txt", "r")
data = file.readlines()[0] # this is still raw data.
file.close()

#now we need to purge the first and the last bracket.
index_lastbr = data.rfind("]")
intermediate_data = data[1:index_lastbr] # here I remove the encapsulating ->[<- and ->]<-
data_list_unformatted = intermediate_data.split("],[")

for index in range(len(data_list_unformatted)):
    item = data_list_unformatted[index]
    if "[" in item:
        data_list_unformatted[index] = item[1:]
    elif "]" in item:
        data_list_unformatted[index] = item[:-1]
# the data is now ["'data',high, open, low, close, volume, etc","'data',high, open, low, close, volume, etc" ]

splitted_list = [] # this becomes a list of lists where every 'column' is a separate string
for item in data_list_unformatted:
    splitted_list.append(item.split(","))

# so instead of ["'data',high, open, low, close, volume, etc","'data',high, open, low, close, volume, etc"]
# it is now [["'data'","high", "open", "low", "close", "volume", "etc"],["'data'","high", "open", "low", "close", "volume", "etc"]]

newfile = open("corrected_data.csv", "w") # here we start writing it to a file

newfile.write('"data";high;open;low;close;volume;etc;\n')

for listitem in splitted_list:
    for item in listitem:
        newfile.write(item + ";")
    newfile.write("\n")

newfile.close()
