Solve the following python programming problem given the following code:
def _get_status_of_claim(self, txid, name, sd_hash) : 
    d = self.get_claims_from_tx (txid) 
    def get_status(claims) : 
        if (claims is None) : 
            claims = [] 
for claim in claims : 
            if ('in claim trie' in claim) : 
                if (('name' in claim) and (str (claim ['name']) == name) and ('value' in claim)) : 
                    try : 
                        value_dict = json.loads (claim ['value']) 
except (ValueError, TypeError) : 
                        return None 
claim_sd_hash = None 
                    if ('stream_hash' in value_dict) : 
                        claim_sd_hash = str (value_dict ['stream_hash']) 
if (('sources' in value_dict) and ('lbrynet_sd_hash' in value_dict ['sources'])) : 
                        claim_sd_hash = str (value_dict ['sources'] ['lbry_sd_hash']) 
if ((claim_sd_hash is not None) and (claim_sd_hash == sd_hash)) : 
                        if (('is controlling' in claim) and claim ['is controlling']) : 
                            return (name, 'valid')

                            return (name, 'pending')
