Why does changing the sum order returns a different result?
... and then rounded to the nearest representable number. Here are two sums:
1/3 + 2/3 + 2/3 = (0.3333 + 0.6667) + 0.6667
= 1.000 + 0.6667 (no rounding needed!)
= 1.667 (where 1.6667 is rounded to 1.667)
2/3 + 2/3 + 1/3 = (0.6667 + 0.6667) + 0.3333
= 1....
Sort a list of tuples by 2nd item (integer value) [duplicate]
...
Try using the key keyword with sorted().
sorted([('abc', 121),('abc', 231),('abc', 148), ('abc',221)], key=lambda x: x[1])
key should be a function that identifies how to retrieve the comparable element from your data structure. In your case, it is the second element of the tupl...

particularly simple string, a string with no repeated characters:
