I get this message when running my python in cmd "Indentation error expected an indented block expected" -

import random import time name=input("welcome game name")  print(("this numbers game"),(name), ("you playing against computer")) print  ("the idea of game closer computer 21 without  going on 21") ,ready="n" ready = input("are ready play game?").lower if ready == "yes" or ready =="y": score=0 

the error coming , saying line above while(score)<21 and(ready=="y" or ready == "yes" or ready =="yes" or ready ==

"yes" or ready =="y"): player1=random.randint(1,21) score=(score+player1)  time.sleep(3) print(("you have scored"),(score)) if score<21: ready=input("do want add more score") if score>21: print("sorry on 21 went bust computer wins") else: print("ok done lets see computer gets") 

(ignore line please) computerscore=0 while(computerscore)<21 , (computerscore)<(score): computer=random.randint(1,21) computerscore=(computerscore+computer)

time.sleep(3) print(("the computer has scored"),(computerscore)) if(computerscore)<=21 , (computerscore)>(score):  print("sorry computer wins") else: print("you win done") break 

i ran in cmd

you have indent blocks after conditions lines, that's how python understands if you're still in condition or not.

if a>b:     print b     print "i'm still in case a>b" else:     print 

use tab or 4 spaces indent.
