  1. POWhy does my python dictionary not updating properly?
    text
    copied!<p>Hello I am trying to store my words I translate using the google api so I don't have to do the same translation twice. So here is my code:</p> <pre><code>def loadtransdict(fro, to): try: tdictf = open("transdict"+fro+"-"+to+".txt", "r") pairs = tdictf.read().split(",") tdictf.close() tdict = {} for pair in pairs: tdict[pair.split(":")[0]] = pair.split(":")[1] return tdict except: tdictf = open("transdict"+fro+"-"+to+".txt", "w") tdictf.close() return {} else: return None def writetodict(fro, to, sword, dword): try: tdictf = open("transdict"+fro+"-"+to+".txt", "r") if tdictf.read() == "": tdictf = open("transdict"+fro+"-"+to+".txt", "a") tdictf.write(sword+":"+dword) else: tdictf = open("transdict"+fro+"-"+to+".txt", "a") tdictf.write(","+sword+":"+dword) tdictf.close() except: return None def translate(original_word, fro, to): tdict = loadtransdict(fro, to) if original_word in tdict: return tdict[original_word] else: print original_word print tdict #mm = requests.get('http://api.mymemory.translated.net/get?q='+word+'&amp;langpair='+fro+'|'+to) gt = requests.get('https://www.googleapis.com/language/translate/v2?key=MYKEY='\ +original_word+'&amp;source='+fro+'&amp;target='+to+'&amp;prettyprint=false') translated_word = re.search("translatedText\":\"(.*)\"", gt.text).group(1) writetodict(fro,to,original_word,translated_word) return translated_word </code></pre> <p>where transdicten-es.txt is a file containing translations written to it in the following format: </p> <blockquote> <p>constantly:constantemente,commanded:ordenado,damp:humedad,mistaken:equivocado,dignity:dignidad</p> </blockquote> <p>My trouble is that often words that have already been translated end up being translated again, not just retrieved from the dictionary and I cannot work out why! If it helps, translate() is being called many 1000s of times in a row in a for loop. Thanks.</p>
