What is the meaning of vertical bar in array dtype ('|S58')

Question

I have an error when I tried to do

np.savetxt(f, te_filename)

It returns an error of

% (str(X.dtype), format))


        

Answer 1

It's a byte order specifier, specifying "byte orders don't apply".

• '=': native
• '<': little-endian
• '>': big-endian
• '|': not applicable
