設計思路

核心程式碼

xList = []
labels = []
names = []
firstLine = True
for line in data:
    if firstLine:
        names = line.decode().strip().split(";")
        firstLine = False
    else:
        row = line.decode().strip().split(";")
        labels.append(float(row[-1]))
        row.pop()
        floatRow = [float(num) for num in row]
        xList.append(floatRow)
