Question

colorramps = re.split("#ramp\[([0-9a-fA-F]{6})\](.+?)#rampend\[([0-9a-fA-F]{6})\]", message)
colorramps.reverse()
if len(colorramps) > 1:
    starttext = colorramps.pop()
    starttext = starttext.replace("$message", getSaveString(text))
    starttext = starttext.replace("$playername", getSaveString(username), 1)
    complete = [starttext]
    while len(colorramps):
        startcolor = getColor(colorramps.pop())
        colors = filter(None, re.split("#over\[([0-9a-fA-F]{6})\]", colorramps.pop()))
        middletxt = colors.pop()
        endcolor = getColor(colorramps.pop())
        middletxt = middletxt.replace("$message", getSaveString(text))
        middletxt = middletxt.replace("$playername", getSaveString(username), 1)
        middletxt = middletxt.decode("utf")
        if len(colors) > 0:
            colors = map(getColor, colors)
            colors.append(endcolor)
            middletxt = rangeOverColors(middletxt, startcolor, colors)
        else:
            middletxt = getRangeString(middletxt, startcolor, endcolor)
        middletxt = middletxt.encode("utf")
        complete.append(middletxt)
        endtext = colorramps.pop()
        endtext = endtext.replace("$message", getSaveString(text))
        endtext = endtext.replace("$playername", getSaveString(username), 1)
        complete.append(endtext)
    message = "".join(complete)
else:
    message = message.replace("$message", getSaveString(text))
    message = message.replace("$playername", getSaveString(username), 1)
return message

大家好！我在replaceColorRamps中进入第128行 middletxt = colors.pop（）

AttributeError：＆＃39; filter＆＃39;对象没有属性＆＃39; pop＆＃39;

我将此代码用于python 2.5，现在将其移植到3.4 ..

有人可以帮助我

你是否在Python 3中运行它？

在Python 2.7 filter()中返回了list，其中.pop()具有filter()功能在Python 3.x filter中返回一个.pop()可迭代对象，而不是。

在您可以从Python 3中的filter colors = list(colors)之前，您需要将其转换为列表。所以添加例如。

colors = filter(...)

在# Remove leading spaces DT[, ITEM := gsub("^\\s*([^\\s].*)$", "\\1", ITEM, perl = TRUE)] # Remove trailing spaces DT[, ITEM := gsub("^(.*[^\\s])\\s*$", "\\1", ITEM, perl = TRUE)] # Substitute center spaces and slash with underscore DT[, ITEM := gsub("\\s+|/", "_", ITEM, perl = TRUE)] # UPPER Case DT[, ITEM := toupper(ITEM)] # Text cleanup DT["CARS" == ITEM, ITEM := "CAR"] DT["TYRE" == ITEM, ITEM := "TIRE"] DT["BRAKE_PADS" == ITEM, ITEM := "BREAKS"] DT["CHAINS" == ITEM, ITEM := "CHAIN"] DT["BICYCLE" == ITEM, ITEM := "BIKE"] # Numeric substitutions DT[, METRIC_1_CLASS := ifelse( "A" == METRIC_1_CLASS , 100 , ifelse( "B" == METRIC_1_CLASS , 1000 , ifelse( "C" == METRIC_1_CLASS , 10000 , NA )))]行之后。在Python 2.7中，这将没有任何效果，因此您的代码将继续在那里工作。请参阅this question for more information 和these docs。
