所以我複製並粘貼您的代碼，並有一個額外的在管線的前部空間161

def lcddata(ch): 

和線路203

lcdcmd(0x01) 

而這一切的代碼有額外的標籤在它不應該

def main(): 

print 'System Ready...' 
URL = 'https://api.thingspeak.com/update?api_key=%s' % key 
print "Wait...." 
while True: 
     (humi, temp)= readDHT() 
     (pressure) =readBmp180() 

     lcdcmd(0x01) 
     lcdstring("Humi#Temp#P(hPa)") 
     lcdstring(humi+'%'+" %sC %s" %(temp, pressure)) 
     finalURL = URL +"&field1=%s&field2=%s"%(humi, temp)+"&field3=%s" %(pressure) 
     print finalURL 
     s=urllib2.urlopen(finalURL); 
     print humi+ " " + temp + " " + pressure 
     s.close() 
     time.sleep(10)
