申し訳ありませんが、私はこれが本当に初めてです..これが完全なpythonスクリプトです。
スクリプトの目的は、2 つの異なる 1 ワイヤ温度センサーを読み取り、HTTP ポストを使用してそれらの値を mysql データベースに書き込むことです。

#Dont forget to fill in PASSWORD and URL TO saveTemp (twice) in this file
sensorids = ["28-00000", "28-000004"]
avgtemperatures = []
for sensor in range(len(sensorids)):
temperatures = []
for polltime in range(0,3):
text = '';
while text.split("\n")[0].find("YES") == -1:
# Open the file that we viewed earlier so that python can see what is in it. Replace the serial number as before.
tfile = open("/sys/bus/w1/devices/"+ sensorids[sensor] +"/w1_slave")
# Read all of the text in the file.
text = tfile.read()
# Close the file now that the text has been read.
tfile.close()
time.sleep(1)
# Split the text with new lines (\n) and select the second line.
secondline = text.split("\n")[1]
# Split the line into words, referring to the spaces, and select the 10th word (counting from 0).
temperaturedata = secondline.split(" ")[9]
# The first two characters are "t=", so get rid of those and convert the temperature from a string to a number.
temperature = float(temperaturedata[2:])
# Put the decimal point in the right place and display it.
temperatures.append(temperature / 1000 * 9.0 / 5.0 + 32.0)
avgtemperatures.append(sum(temperatures) / float(len(temperatures)))
print avgtemperatures[0]
print avgtemperatures[1]
session = requests.Session()
# Getting a fresh nonce which we will use in the authentication step.
nonce = session.get(url='http://127.0.0.1/temp/saveTemp.php?step=nonce').text
# Hashing the nonce, the password and the temperature values (to provide some integrity).
response = hashlib.sha256('{}PASSWORD{}{}'.format(nonce.encode('utf8'), *avgtemperatures).hexdigest())
# Post data of the two temperature values and the authentication response.
post_data = {'response':response, 'temp1':avgtemperatures[0], 'temp2': avgtemperatures[1]}
post_request = session.post(url='http://127.0.0.1/temp/saveTemp.php', data=post_data)
if post_request.status_code == 200 :
print post_request.text
以下は、私が得る新しいエラーです。
