I have data like this form:

```
X=[]; 
X=[X,0.114]; 
X=[X,0.749]; 
X=[X,0.358]; 
    .
    .
    .

```

I want to extract the values in the lists in a single list, as:

```
X = [0.114, 0.749, 0.358,...]

```

I used this code but it doesn't work:

```
import pandas as pd
data = pd.read_csv('Xtest.txt')
count = data['X']

```

Could you please help me pull the values?
And thank you.
