KeyError in weather station project
0
I'm getting a error like this with a weather station project I'm working on. The error is as follows:
Traceback (most recent call last):
File "wind_direction_byo.py", line 27, in <module>
print('Unknown value: ' + str(wind) + ' ' + str(volts[wind]))
KeyError: 0.0
This is the source file code that i tried to execute:
from gpiozero import MCP3008
import time
import math
adc = MCP3008(channel=0)
count = 0
values =
volts = {0.4: 0.0,
1.4: 22.5,
1.2: 45.0,
2.8: 67.5,
2.7: 90.0,
2.9: 112.5,
2.2: 135.0,
2.5: 157.5,
1.8: 180.0,
2.0: 202.5,
0.7: 225.0,
0.8: 247.5,
0.1: 270.0,
0.3: 292.5,
0.2: 315.0,
0.6: 337.5}
while True:
wind = round(adc.value*3.3,1)
if not wind in volts:
print('Unknown value: ' + str(wind) + ' ' + str(volts[wind]))
else:
print('Found: ' + str(wind) + ' ' + str(volts[wind]))

You do the check if wind is in your volts dictionary, and when it is missing, you still try to access it:
if not wind in volts:
print('Unknown value: ' + str(wind) + ' ' + str(volts[wind]))
If it is not present, you cannot access it. Remove it from your print:
if not wind in volts:
print('Unknown value: ' + str(wind))
