hi,

i trying compare 2 strings shown above. first of all, surprised python comparing strings of numbers. firstly thought compare lengths, different values it's giving exact values , astonished. but, '1.1.10' > '1.1.5' it's false... don't know why.... can help...

a = '1.1.10' b = '1.1.5' a, b in zip(a, b):     print(ord(a), ord(b), > b)

49 49 false

46 46 false

49 49 false

46 46 false

49 53 false
