Description

Minor usability improvement

schema = pa.schema([pa.field('a', pa.int64(), nullable=False)])

In [11]: schema                                                                                                                           
Out[11]: a: int64

In [12]: schema[0]                                                                                                                        
Out[12]: pyarrow.Field<a: int64 not null>

I'd like to see

In [11]: schema                                                                                                                           
Out[11]: a: int64 not null

or similar
