我正在編寫一個(gè)腳本，在我的腳本中，我具有以下功能：

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:///%s/%sPR-IT,PM.jpg" % (folder, sku)):

urllib.URLopener().retrieve("http:///%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:///%s/%sPK-PT,PM.jpg" % (folder, sku)):

urllib.URLopener().retrieve("http:///%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:///%s/%sCC-PT,IM.jpg" % (folder, sku)):

urllib.URLopener().retrieve("http:///%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

在我添加嘗試捕獲之前，此方法運(yùn)行良好。 我確實(shí)有if，elif函數(shù)運(yùn)行得很好。 這是我的電話以及在它之前運(yùn)行的代碼的優(yōu)美之處：

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()

我的錯(cuò)誤是：

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 "", line 47, in

NameError: name 'insert_image' is not defined

我不知道第47行是什么意思，因?yàn)樵撜{(diào)用位于第2101行，在我添加嘗試之前，它再次發(fā)現(xiàn)該函數(shù)很好。 當(dāng)我像現(xiàn)在看到的那樣添加嘗試時(shí)，我還將第一個(gè)提交切換到insert_image調(diào)用之前，而在我們調(diào)用insert_image之后則提??交之前。 我檢查了縮進(jìn)，空格和制表符w /無濟(jì)于事。

我使用TextMate，當(dāng)我從TextMate運(yùn)行腳本時(shí)，在這里出現(xiàn)語法錯(cuò)誤：

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

它指向（上的（文件夾。。。但是我看不到語法錯(cuò)誤。請(qǐng)幫忙。我已經(jīng)在這個(gè)腳本上工作了幾周了，這應(yīng)該是最后一次運(yùn)行測(cè)試并稱其為:(

總結(jié)
