I have a dataset with multiple strings. I want to associate each of these strings to a float, "randomly" distributed in the `[0:1]` range. Examples:

```
>>> myfunction(string_1)
0.26756754
>>> myfunction(string_2)
0.86764534

```

`random` does not fulfill my need because it does not take any string as input/deterministic parameter. I am looking for something more like a hash function.
