Well, if you're reading the data in as a list, just do `np.array(map(float, list_of_strings))`

(or equivalently, use a list comprehension). (In Python 3, you'll need to call `list`

on the `map`

return value if you use `map`

, since `map`

returns an iterator now.)

However, if it's already a numpy array of strings, there's a better way. Use `astype()`

.

```
import numpy as np
x = np.array(['1.1', '2.2', '3.3'])
y = x.astype(np.float)
```

You can use this as well

```
import numpy as np
x=np.array(['1.1', '2.2', '3.3'])
x=np.asfarray(x,float)
```
