绘制数据时出现matplotlib语法错误

Question

我试图使用matplotlib绘制可视化数据但我收到错误。这是我的代码：

import numpy as np
import datetime
import time
import matplotlib.pyplot as plt
import matplotlib.ticker as mticker
import matplotlib.dates as mdates

data=open('final1.csv','r')
date&time,values = np.genfromtxt(data,delimiter=',',unpack=True,converters={0: mdates.bytespdate2num("%d/%m/%Y %H:%M")})

plt.gca().xaxis.set_major_locator(mticker.MaxNLocator(10))
plt.gca().xaxis.set_major_formatter(mdates.DateFormatter(('%d/%m/%Y %H:%M')))

plt.plot(date&time,values,color='red')

plt.ylabel('Values')
plt.xlabel('Date')

plt.gcf().autofmt_xdate()

plt.show()

我收到以下错误：

date&time,values => np.genfromtxt(data,delimiter=',',unpack=True,converters=0:mdates.bytespdate2num("%d/%m/%Y %H:%M")})  
    ^ SyntaxError: can't assign to operator

我的final.csv文件如下所示：
