Question

我正在尝试从Raspberry pi创建温度和湿度数据的分析代码。我的代码似乎没有工作，因为我继续收到此错误

回溯（最近一次呼叫最后）：文件＆＃34; script_name.py＆＃34;，第19行，在 hour = str（columns [2]）IndexError：元组索引超出范围pi @ raspberrypi~ $

这是我的代码：

import matplotlib.pyplot as plt

f = open('my_data.txt','r')
file_contents = f.read()
f.close()

line_by_line = file_contents.split('\n')
data = line_by_line[4::]
print data

time = []
temperature = []
humidity = []

for line in data[:-1]:
    columns = line.split(':'),(',')
    month = str(columns[0])
    day = str(columns[1])
    hour = str(columns[2])
    min = str(columns[3])
    sec = str(columns[4])
    time_in_seconds = month*(60.0*60.0*24.0*30.0)+day*(60.0*60.0*24.0)+hour*  (60.0*60.0)+min*60.0+sec
    time.append(time_in_seconds)
    humidity.append(columns[5])
    temperature.append(columns[6])

import numpy as np 
humidity = np.array(humidity)
temperature = np.array(temperature)
missing_data_locations = np.where(humidity == 'None')
missing_data_locations = np.where(temperature == 'None')
humidity[missing_data_locations] = '-999'
temperature[missing_data_locations] = '-999'
humidity = humidity.astype(np.float)
temperature = temperature.astype(np.float)
missing_data_locations2 = np.where(humidity == -999)
missing_data_locations2 = np.where(temperature == -999)
humidity[missing_data_locations2] = np.nan
temperature[missing_data_locations2] = np.nan

print time
print temperature
print humidity

plt.close('all')

fig = plt.figure()

ax1 = fig.add_subplot(211)
ax1.plot(time,temperature,'r')
ax1.set_ylabel('temperature (deg. C)')
ax2 = fig.add_subplot(212)
ax2.plot(time,humidity,'b')
ax2.set_ylabel('humidity (%)')
ax2.set_xlabel('time (seconds)')

plt.savefig('/home/pi/my_fig.png')

plt.show()

Raspberry Pi温度湿度传感器，元组索引超出范围
