You can test for the prefix with the `startswith()` method and use string
slicing to create a new string without the prefix:
In [3]: prefix = 'Timeout '
In [4]: longname = 'Timeout N_Bs'
In [5]: longname.startswith(prefix)
Out[5]: True
In [6]: longname = longname[len(prefix):]
In [7]: longname
Out[7]: 'N_Bs'
