Hi,

I was wondering if anyone knew what encoding a string read from a file by a python program is in?

I am having trouble comparing to string values, 1 of which is an attribute of a class i have defined.

Heres the part of the code that is giving me the problem:-

def DrawWedge(loc,im,x,y,dir):
    colour =0x000000#black
    if(loc.locationType=='library'):
        colour = 0xff0000#red
        print colour
    elif(loc.locationType=='coffee'):
        colour = 0x800000#darkred
        print colour
    elif(loc.locationType=='tourist'):
        colour = 0x0000FF#blue
        print colour
    else: 
        colour =0x000000#black
        print "else"
        print colour

Its unicode as well.

Btw, what type is loc.locationType? The rest of the code might help to solve this faster.

Please make sure both are same type, either unicode or non-unicode. For example u'library' and 'unicode' can be different strings.

Cheers,

This is the location class:-

class location(object):
	xcoord =0
	ycoord =0
	locationType =""

I understand that they must be the same type e.g. unicode. How do you change the type to be unicode?

Note that I also remove the \n from the line that is read in from the file.

Thanks.

locationType =u""

Now thats unicode.

Just use the unicode() function to convert to unicode.

locationType=unicode(locationType)

Hi,

I have tried converting both strings that I want to compare into unicode and it still fails(I know the strings are the same but loc.locationType=="library" is false instead of True).

I have just went through the code step-by-step using the python shell and everything worked as expected.

I really dont know why this comparison is failing.

Any more suggestions??

That's not unicode. Did you really try loc.locationType == u"library" as Croozeus suggested?

Well, you might try also loc.locationType is u"library" but I doubt it would make any change. Comparison operation "is" checks whether two objects are same.

"jouni" != u"jouni",
