Python 从行中提取变量数据

Question

我需要从 HTML 文件中提取几条数据到 excel sheet 中。我已经提取了数据，现在我只需要从行中提取它。这是一个例子：

"501.92secs: iPhone 5s_DownStream HTTP_TCP_Downlink_1 : ILOAD = **12.000** Mbps OLOAD = **4.999** Mbps FRATE = 4.980 Mbps L4 Goodput = 4.788 Mbps Packet Loss = 0.38 SLA Result = **FAIL**<font color=white>"

我已经把我需要提取的项目加粗了。因为这些值随每个文件而变化，并且需要将它们保存到变量名中，所以我真的不知道从哪里开始。

好吧，这是一个 hacky 的答案...它看起来并不漂亮，但如果您的字符串模式保持不变，您应该能够得到结果。

string = "501.92secs: iPhone 5s_DownStream HTTP_TCP_Downlink_1 : ILOAD = **12.000** Mbps OLOAD = **4.999** Mbps FRATE = 4.980 Mbps L4 Goodput = 4.788 Mbps Packet Loss = 0.38 SLA Result = **FAIL**<font color=white>"


import re
def getnumbers(string,patterns):
 results = []
 for pattern,number in patterns.items():
    match = re.search(pattern,string)
    valuestart = match.span()[1]
    results.append([pattern,(string[valuestart+3:valuestart+number+3])])
 return results

#If you need obtain more values, add them to the dictionary in the argument.
#The number next to each pattern indicates the expected size of the result. 
print(getnumbers(string,{"ILOAD =":7,"OLOAD =":7,"Result =":4})) #[['Result =', 'FAIL'], ['OLOAD =', '4.999**'], ['ILOAD =', '12.000*']]
