How to extract partial number from a list of strings?

I have a list of strings

['apple_orange_percentage_0.709_0.752',
 'apple_orange_percentage_0.752_0.786',
 'apple_orange_percentage_0.673_0.709']

I need just a list of the unique numbers here:

[0.673, 0.709, 0.752, 0.786] 

Could someone guide me on how to get there?

>Solution :

If you’re not concerned about the order of the values in your output list then:

data = ['apple_orange_percentage_0.709_0.752',
 'apple_orange_percentage_0.752_0.786',
 'apple_orange_percentage_0.673_0.709']

s = set()

for sv in data:
    s.update(map(float, sv.split('_')[-2:]))

print(list(s))

output:

[0.673, 0.752, 0.709, 0.786]
