Unicode error

[AmyKlug]

Hi,

When i am running this code i am getting a Unicode error half way through. Not sure what mxd/layer file name is hanging it up (line 33) on but not sure where to put the fix (line 7 - or if this is the correct fix) either.

import arcpy, os

#code adds mxd name and layer path name to text file separated by a comma
arcpy.env.overwriteOutput = True


#def Utf8EncodeArray(oldArray):
    #newArray = []
    #for element in oldArray:
        #if isinstance(element, unicode):
        #newArray.append(element.encode("utf-8"))
    #else:
        #newArray.append(element)
    #return newArray


path = "////serverpath"
#path2 =
mxdlst = []
txt = open("text file path", 'w')
print "making mxd list"
for root, dirs, files in os.walk(path):
    for fname in files:
        if fname.endswith(".mxd"):
            mxd = root + '\\' + fname
            mxdlst.append(mxd)
del mxd, fname
for mapdoc in mxdlst:
    mxd = arcpy.mapping.MapDocument(mapdoc)
    for df in arcpy.mapping.ListDataFrames(mxd, "*"):
        for lyrlst in arcpy.mapping.ListLayers(mxd, "*", df):
            if lyrlst.supports("DATASOURCE"):
                txt.write(mapdoc + "," + lyrlst.workspacePath + "\\" + lyrlst.name + "\n")
                print "adding" + mapdoc + "," + lyrlst.workspacePath + "\\" + lyrlst.name + "\n"
            else:
                txt.write(mapdoc + "," + lyrlst.name + "\n")
                print "adding" + mapdoc + "," + lyrlst.name + "\n"
txt.close()
del mxd, df, lyrlst, mapdoc, mxdlst

is this how to do it?

txt.write(u'mapdoc' + "," + u'lyrlst.workspacePath' + "\\" + u'lyrlst.name' + "\n")

This will not be the solution due to a number of reasons:

If you use something like u'lyrlst.workspacePath', then you create a unicode text contains the text lyrlst.workspacePath and not the content of the variable. For that you would have to use unicode(lyrlst.workspacePath).

The other aspect is combining a normal str with a unicode. In your line there are still some elements that are of type str ("," "\\", "\n", etc).

I have seen posts where they recommend using the codecs library to write unicode to text file:

import codecs
with codecs.open(YourOutputFile, 'w', encoding='utf-8') as f:
    f.write(unicode_text)

Please take the time to read this article: Solving Unicode Problems in Python 2.7 | Azavea Labs It can help to clear thing up for you.
