Hi, i need to how to make the if statement of inside if. Incase 1st if condition as true it need to enter or else need to proceed on the last else. I tried to explain on my Python code below. I don’t know how to implement this on ob2. If anyone can pls help on it

var = 1000
if var < 200:
   print "Expression value is less than 200"
   if var == 150:
      print "Which is 150"
   else:
      print "Which is not 150"
else:
   print "More thaan 200"

print "Good bye!"

OUTPUT:-
More thaan 200
Good bye!

This was python code. unfortunately idk the two if shows error . I need to achieve the output what i showed . Anyway to do on loli. Or only way to use interpreter ??

Also write the code you used on ob, then i can edit to rectify it
