python 数据绘图处理

这个是数据的截图

根据下面公式获取数据的y 值,x=i++
把(x,y)坐标的散点图绘制在坐标系中,对点集合平滑处理为曲线
if filetype = ='2'
bandwidth = 1000 * 8 *fileByte/(totalTime-Rttime)

    fig = plt.figure(dpi=128, figsize=(15,9))
    #Splt = fig.add_subplot(111)
    plt.plot(cows,lows, '-', label = 'Quantity 1', c='red')
    #plt2 = plt.twinx()
    #plt2.plot(datas, lows, '-', label = 'Quantity 2', c='blue')
    plt.legend(loc=0)
    plt.grid()
    plt.title("Levels",fontsize = 24)
    plt.xlabel('nums',fontsize = 16)
    plt.ylabel('level',fontsize= 16)
    #plt2.ylabel('bwe',fontsize= 16)
    plt.show()
    
    

运行结果及报错内容

Input In [9]
lows.append(asim)
^
SyntaxError: invalid syntax

我的解答思路和尝试过的方法

if filetype = ='2'
bandwidth = 1000 * 8 *fileByte/(totalTime-Rttime)

我想要达到的结果

jupyter 在坐标轴内输出点的数据,近似得到一条曲线

第35行括号没匹配,改为

asim =int(Downs * 1000 * 8 /(int(totaltime - int(rtts ))))
