Removing a 'b' from the Python String

Question

I am currently using the Numpy package (version 1.12.1) in Spyder (Python 3.6). For some reason I am unable to remove 'b's which appear before strings in the IPython Console.

   import numpy as np

   student = np.dtype([('name', 'S20'), ('age', 'i1'), ('code', 'i4')])
   print (student)

   recordsvar = np.array([('Cordelia',28,100),('Cordelia',29,101),
   ('Cordelia',30,102)], dtype=student)
   print (recordsvar)

The output is

[(b'Cordelia', 28, 100) (b'Cordelia', 29, 101) (b'Cordelia', 30, 102)]

How do I remove the 'b' in from of Cordelia?

Thanks in advance

The b' indicates, that your data is stored as bytes, the numpy datatype is S20. If you want to store characters, use unicode as datatype: U20:

student = np.dtype([('name', 'U20'), ('age', 'i1'), ('code', 'i4')])

Apologies. I didn't realise I had forgotten to accept it. Thanks for reminding me. – cordelia Oct 21 '17 at 23:53
