There's something with that last function that is really tripping me up. I keep getting errors. I know aDictionary is not defined but I do not even know what to define it as! Any of you guys have an idea? Thanks.

有最后一个功能的东西真的让我感到沮丧。我一直在收到错误。我知道aDictionary没有定义，但我甚至不知道将它定义为什么！你们俩有个主意吗？谢谢。

with open("some_file.txt","W") as f:
    print >> f, "Something goes here!"

its hard to say without your errors. .. but you almost certainly need to have aDictionary defined

没有你的错误很难说。 ..但你几乎肯定需要定义一个字典

also probably something like

也可能是这样的

def DisplayCounts(InputFile): 
    print "\n"   
    numCount = 0
    dotCount = 0
    commaCount = 0
    lineCount = 0
    wordCount = 0

    with open(InputFile, 'r') as f:
            for line in f:
                wordCount+=len(line.split())
                lineCount+=1
                for char in line:
                        if char.isdigit() == True:
                            numCount+=1
                        elif char == '.':
                            dotCount+=1
                        elif char == ',':
                            commaCount+=1

    return dict(numbers=numCount,
    comma=commaCount,
    dot=dotCount,
    line=lineCount,
    word=wordCount)

result = DisplayCounts("someinput.txt")
print result
