我目前正在開發一個程序，該程序從 csv 文件中獲取一組列表，并將它們分組在一起。我想出的程序是：List_one = []                  with open("trees.csv") as f:        skiplines = f.readline()        for line in f:          res = line.split(" ")              List_one.append(res)          for i in List_one:        (i[0]) = (i[0]).rstrip("\n")    print (List_one)我現在得到的是一組列表，但問題是這些列表是字符串，我希望它們作為浮點數。列表如下所示：[['1,8.3,70,10.3'], ['2,8.6,65,10.3'], ['3,8.8,63,10.2'], ['4,10.5,72,16.4'], ['5,10.7,81,18.8'], ['6,10.8,83,19.7'], ['7,11.0,66,15.6'], ['8,11.0,75,18.2'], ['9,11.1,80,22.6'], ['10,11.2,75,19.9'], ['11,11.3,79,24.2'], ['12,11.4,76,21.0'], ['13,11.4,76,21.4'], ['14,11.7,69,21.3'], ['15,12.0,75,19.1'], ['16,12.9,74,22.2'], ['17,12.9,85,33.8'], ['18,13.3,86,27.4'], ['19,13.7,71,25.7'], ['20,13.8,64,24.9'], ['21,14.0,78,34.5'], ['22,14.2,80,31.7'], ['23,14.5,74,36.3'], ['24,16.0,72,38.3'], ['25,16.3,77,42.6'], ['26,17.3,81,55.4'], ['27,17.5,82,55.7'], ['28,17.9,80,58.3'], ['29,18.0,80,51.5'], ['30,18.0,80,51.0'], ['31,20.6,87,77.0']]正如你們所看到的，我也不能在列表一上使用 float() ，因為列表本身就是一個完整的字符串。有沒有辦法可以通過索引拆分列表，這樣我就得到：['1', '8.3', '70', '10.3'].....歡迎任何幫助。
