Question

这是我的代码....我的代码没有错....识别行161的错误... 像这样的错误......第161行......缩进错误：unindent与任何外部缩进级别都不匹配“

帮助救命帮助

所以我复制并粘贴你的代码，第161行前面有一个额外的空间

def lcddata(ch):

和第203行

lcdcmd(0x01)

并且所有这些代码都有额外的标签，它不应该

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)
