comparing dictionaries to find the identical keys

[Beema shafreen]

hi everybody ,
i need to compare two dictionary's key. I have written a script
gene_symbol = {}
probe_id = {}
result = {}
def getGene(fname):
        fh = open(fname , 'r')
        for line in fh:
                yield line
        fh.close()
for line in getGene("symbol_hu133"):
        data1= line.strip().split('#')
        probe_give = data1[0].strip()
        gene_give = data1[1].strip()
        gene_symbol[probe_give] = gene_give
        #print gene_symbol.keys()
for line in getGene("gds1428.csv"):
        data = line.strip().split(',')
        probe_get = data[0].strip()
        probe_id[probe_get] = data
if gene_symbol.keys() == probe_id.keys():
        print gene_symbol.keys(), probe_id.values()


can anybody show me  the error I make here ,while comparing the keys of two
dictionaries so that i print the values of the  dictionaries whoes Keys are
Identical
