[英]Python Exception Handling with in a loop
An exception occurs when my program can't find the element its looking for, I want to log the event within the CSV, Display a message the error occurred and continue.当我的程序找不到它要查找的元素时会发生异常,我想在 CSV 中记录事件,显示发生错误的消息并继续。 I have successfully logged the event in the CSV and display the message, Then my program jumps out of the loop and stops.我已成功将事件记录在 CSV 中并显示消息,然后我的程序跳出循环并停止。 How can I instruct python to continue.我如何指示 python 继续。 Please check out my code.请检查我的代码。
sites = ['TCF00670','TCF00671','TCF00672','TCF00674','TCF00675','TCF00676','TCF00677']`
with open('list4.csv','wb') as f:
writer = csv.writer(f)
try:
for s in sites:
adrs = "http://turnpikeshoes.com/shop/" + str(s)
driver = webdriver.PhantomJS()
driver.get(adrs)
time.sleep(5)
LongDsc = driver.find_element_by_class_name("productLongDescription").text
print "Working.." + str(s)
writer.writerows([[LongDsc]])
except:
writer.writerows(['Error'])
print ("Error Logged..")
pass
driver.quit()
print "Complete."
Just put the try/except
block inside the loop.只需将try/except
块放入循环中即可。 And there is no need in that pass
statement at the end of the except
block.并且不需要在except
块末尾的pass
语句中。
with open('list4.csv','wb') as f:
writer = csv.writer(f)
for s in sites:
try:
adrs = "http://turnpikeshoes.com/shop/" + str(s)
driver = webdriver.PhantomJS()
driver.get(adrs)
time.sleep(5)
LongDsc = driver.find_element_by_class_name("productLongDescription").text
print "Working.." + str(s)
writer.writerows([[LongDsc]])
except:
writer.writerows(['Error'])
print ("Error Logged..")
NOTE It's generally a bad practice to use except
without a particular exception class, eg you should do except Exception:...
注意在没有特定异常类的情况下使用except
通常是一种不好的做法,例如,您应该使用except Exception:...
