why there is a "#" in header

There is always a # in the first column of my header:

np.savetxt((self.foldername + '/' + 'XYZ.csv'), XYZ, fmt='%1.6f', delimiter=',',header="X(um),Y(um),Z(nm))

I got the header like this

#X(um),Y(um),Z(nm)

How to avoid the #.

it inserts the # because that line is a comment, and the default character for comments is the symbol #, as you can read in the documentation here.

If you want to get rid of it, pass comments='' as option to savetxt.

from: numpy.savetxt without hash mark at beginning of header line

Here is the relevant bit from the loadtxt docstring describing the comments keyword and its effect on the header and other things.

comments : str, optional String that will be prepended to the header and footer strings, to mark them as comments. Default: '# ', as expected by e.g. numpy.loadtxt.
