函数未定义但实际上已定义

Question

我正在写一个脚本，在这个脚本里有一个函数：

def insert_image(cursor, object_id, sku):
    product_obj = core.Object.get(object_id)
    string_sku = str(sku)
    folder = string_sku[0] + string_sku[1] + string_sku[2]
    found_url = False
    # KLUDGE This is ugly and redundant, however putting this in an if elif elif else throws error when url not found
    # try this url first
    try urllib.urlopen("http://<path to images>/%s/%sPR-IT,PM.jpg" % (folder, sku)):
        urllib.URLopener().retrieve("http://<path to images>/%s/%sPR-IT,PM.jpg" % (folder, sku), "%sPR-IT,PM.jpg" % (sku))
        found_url = True
    except:
        found_url = False
    # If that one didn't work try this one
    if found_url == False:
        try urllib.urlopen("http://<path to images>/%s/%sPK-PT,PM.jpg" % (folder, sku)):
            urllib.URLopener().retrieve("http://<path to images>/%s/%sPK-PT,PM.jpg" % (folder, sku), "%sPK-PT,PM.jpg" % (sku))
            found_url = True
        except:
            found_url = False
    # If still nothing, one last attempt
    if found_url == False:
        try urllib.urlopen("http://<path to images>/%s/%sCC-PT,IM.jpg" % (folder, sku)):
            urllib.URLopener().retrieve("http://<path to images>/%s/%sCC-PT,IM.jpg" % (folder, sku), "%sCC-PT,IM.jpg" % (sku))
            found_url = True
        except:
            found_url = False
    # We failed to find an image for this product, it will have to be done manually
    if found_url == False:
        log.info("Could not find the image on notions")
        return False

    # Hey we found something! Open the image....
    send_image = open('%sPK-PT,PM.jpg' % sku, 'r')
    # ...and send it for processing
    if product_obj.set_image(send_image, 5, 1) == False:
        return False
    else:
        log.debug("Inserted Image")
        return True

这个函数运行得很好，直到我添加了错误处理的部分（try catches）。之前我有用if和elif，函数运行得也很顺利。这里是我调用这个函数的代码，以及在调用之前的那段代码：

   if rollback == False:
        # Nah -- it's all good SAVE IT!
        count += 1
        log.debug("INSERT %s" % count)
        conn.commit()
    else:
        # Yeah something went wrong, errors reported why, roll it back
        conn.rollback()
        log.debug("skipped %s" % skip_count)

  # Insert images
        if rollback == False:
            sku = row[0]
            if insert_image(cursor, object_id, sku) == False:
                log.error("Could not get the image inserted for product: %s" % object_id)
                conn.rollback()
            else:
                conn.commit()

我遇到的错误是：

16:33:46,153 DEBUG [pylons-admin] Inserted Description
16:33:46,164 DEBUG [pylons-admin] Inserted Attributes
16:33:46,164 DEBUG [pylons-admin] INSERT 1
Traceback (most recent call last):
File "<console>", line 47, in <module>
NameError: name 'insert_image' is not defined

我不明白第47行是什么意思，因为调用是在第2101行。之前我添加错误处理之前，函数运行得很好。我还把第一个提交（commit）放在了insert_image调用之前，像你现在看到的那样，之前提交是在调用insert_image之后。我检查了缩进、空格和制表符，但都没有找到问题。

我使用的是TextMate，当我从TextMate运行这个脚本时，这里出现了一个语法错误：

 try urllib.urlopen("http://<path to images>/%s/%sPR-IT,PM.jpg" % (folder, sku)):

错误指向了(folder...的那个括号，但我看不出哪里有语法错误。请帮帮我。我已经在这个脚本上工作了几周，这本来是最后一次测试，想要结束这个项目的。 :(

错误处理脚本执行函数调用代码缩进版本控制调试语法错误 try catch
