Nested IF 2

#Example of nested IF using integers
#Input number is compared changing output

var = int(input("Enter a number... ")) #collect a number
if var > 1000: #upper limit
   print("Over 1000")
elif var >100 <1000: #middle limit
   print ("Between 1000 and 100")
elif var <100: #lower limit
      print ("Lower than 100")
      if var >=50 <100: #lower limit between 50 and 100
         print("Between 50 and 100")
      else: #lower limit 'catch all' lower than 50
         print("Lower than 50")
