Hi I am new to python and wanted to sort these values based on the numeric values present in each tuple

b={('shoe',0.98),('bag',0.67),('leather',0.77)}

I have tried changing it into a list but then the tuple elements cannot be changed Thanks in advance

CodePudding user response：

Python sets are unordered, so you can’t sort them. But you can sort the elements in a set using the sorted function and passing a lambda that selects the second item of a tuple (since the set elements are tuples and you want to sort by the second elements of the tuples) to the key parameter. This returns a list:

out = sorted(b, key=lambda x:x[1])

Output:

[('bag', 0.67), ('leather', 0.77), ('shoe', 0.98)]

Or you can use operator.itemgetter (there is also attrgetter):

from operator import itemgetter

out = sorted(b, key=itemgetter(1))
