`lcd_init() lcdcmd(0x01) lcdstring("Circuit Digest")`. next time isolate the lines instead of posting your whole code. You won't even have to post here. — Jean-François Fabre, Mar 20 '17 at 17:18
You have two different indent level...one with 2 spaces and one with tabs. And there's a extra space in front `lcdcmd(0x01)` and what Jean said — Taku, Mar 20 '17 at 17:20
as you might have noticed - Python is white-space / indentation-sensitive. remove the extra space and pretend you never posted this to Stack Overflow — Antti Haapala -- Слава Україні, Mar 20 '17 at 17:21

So I copy and pasted your code and there is an extra space in front of line 161

def lcddata(ch):

and line 203

lcdcmd(0x01)

and all this code has extra tabs in it it shouldn't

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)

Welcome Matthew! Thank you for willing to help, but the usage here is not to write answers to such questions who were only caused by simple typos (especially when someone already noted that in the comments!) Furthermore, the question is one month old, so there's little chance that your work will help the OP. But keep on the good work! — Thierry Lathuille, Apr 19 '17 at 17:40
