Python 3.x 用Python解析数据输出

所以我有这个代码：

si.get_stats("aapl")

返回此垃圾：

这是一个第三方功能，从Yahoo Finance中删除数据。我需要这样的东西

def func( si.get_stats("aapl") ):
     **magic**
     return Beta (3Y Monthly)

---

具体来说，我希望它返回与Beta关联的数字，而不是实际文本。

我假设函数调用为表中的每一行返回一个字符串或字符串列表，而不是写入标准输出

要获取与Beta（每月3次）或任何其他参数名称相关的值，请执行以下操作：

1） 如果返回值是一个字符串，其格式如上表所示，则应在每行末尾\n显示。因此，您可以将该字符串拆分为一个列表，然后迭代查找参数名，然后再次拆分以获取与其关联的数字

# Split the single formatted string to a list of elements, each element
# is one line in the table
str_lst = si.get_stats("aapl").split('\n')
for line in str_lst:
    # change Beta (3Y Monthly) to any other parameter required.
    if 'Beta (3Y Monthly)' in line:
        # split this line with the default split value of white space
        # this should provide a list of elements split at each white space.
        # eg : ['31', 'Beta', '(3Y', 'Monthly)', '1.21'], the numeric value is the
        # last element. Strip to remove trailing space/newline.
        num_value_asStr = line.split()[-1].strip()
return num_value_asStr 

2） 如果它已经返回了一个列表，那么只需迭代列表项并使用上面的If条件，拆分所需的列表元素以获得与参数关联的数值

str_lst = si.get_stats("aapl")
for line in str_lst:
    # change Beta (3Y Monthly) to any other parameter required.
    if 'Beta (3Y Monthly)' in line:
        # split this line with the default split value of white space
        # this should provide a list of elements split at each white space.
        # eg : ['31', 'Beta', '(3Y', 'Monthly)', '1.21'], the numeric value is the
        # last element. Strip to remove trailing space/newline.
        num_value_asStr = line.split()[-1].strip()
return num_value_asStr
