I downloaded a csv table from a database using SQL. One of the fields has values like so:

```
'[0.1234,0.0,0.0]'

```

I want to convert this string to a python list to get the first value. I only know how to convert strings to ints and floats... is there any way to de-string this object? The table I got from SQL is from a web-based viewer, I'm not getting it from my command line.
