PyTube: PrivateVideo exception not working

一个人想着一个人 提交于 2021-02-17 05:29:24
问题 I wrote a code that will print all videos' name on the playlist. The problem is when it tries to print the name of the video that is private. I wrote an exception from Github that the owner wrote but it still doesn't work. It should skip this one video and go to another one but it doesn't and the program crashes. Here is my code: import pytube from pytube.exceptions import VideoPrivate pl = pytube.Playlist("https://www.youtube.com/playlist?list=PLB1PGaMZkETOixDfsnKIOkfJS_cToCHSt") for video

Python looping with try and except

左心房为你撑大大i 提交于 2021-02-08 05:02:06
问题 I am trying to write a program that reads numbers input by the user until the user types done. If the user types a non-number other than "done," I want to return an error message like "please enter a number number. When the user types "done", I want to calculate the total of the numbers, the number count and the average. I have tried to create a while loop with try and except to catch the non-numeric error other than done. That is part of the trick, a string entry is an error unless the

What is the analogue of EXCEPT clause in SQL in Pandas?

问题 I have a sample pandas dataframe df: col1 col2 col3 col4 0 a 1.0 2.0 3 1 b NaN NaN 6 2 c NaN 8.0 9 3 d NaN 11.0 12 4 e 13.0 14.0 15 5 f 17.0 18.0 19 6 g 21.0 22.0 23 and a second one df1: col1 col2 col3 col4 0 a 1.0 2.0 3 4 e 13.0 14.0 15 5 f 17.0 18.0 19 6 g 21.0 22.0 23 I want to get the subset of df that does not overlaps with df1. In effect I am looking for the equivalent of the EXCEPT operand in SQL. I used the subtract() function -- but this was clearly wrong, as the subtract performs

Python: Multiple try except blocks in one?

一世执手 提交于 2020-07-08 12:47:23
问题 Is there a neat way to have multiply commands in the try block so that it basically tries every single line without stopping as soon as one command yields an error? Basically I want to replace this: try: command1 except: pass try: command2 except: pass try: command3 except: pass with this: try all lines: command1 command2 command3 except: pass Defining a list so I could loop through the commands seems to be a bad solution 回答1: I'd say this is a design smell. Silencing errors is usually a bad

python中try except处理程序异常的三种常用方法

孤者浪人 提交于 2020-03-18 18:37:46
3 月,跳不动了?>>> 如果你在写python程序时遇到异常后想进行如下处理的话,一般用try来处理异常,假设有下面的一段程序: try: 语句1 语句2 . . 语句N except .........: do something ....... 但是你并不知道"语句1至语句N"在执行会出什么样的异常,但你还要做异常处理,且想把出现的异常打印出来,并不停止程序的运行,所以在"except ......"这句应怎样来写呢? 总结了一下 3个方法 : 方法一:捕获所有异常 try: a=b b=c except Exception,e: print Exception,":",e 方法二:采用traceback模块查看异常 #引入python中的traceback模块,跟踪错误 import traceback try: a=b b=c except: traceback.print_exc() 发生异常时,Python能“记住”引发的异常以及程序的当前状态。Python还维护着traceback(跟踪)对象,其中含有异常发生时与函数调用堆栈有关的信息。记住,异常可能在一系列嵌套较深的函数调用中引发。程序调用每个函数时,Python会在“函数调用堆栈”的起始处插入函数名。一旦异常被引发,Python会搜索一个相应的异常处理程序。如果当前函数中没有异常处理程序,当前函数会终止执行

问题 This is my query SELECT PageVisit_ID,TargetSite_ID FROM [A].Datawarehouse.mi.ctb_PageEvent WITH (NOLOCK) EXCEPT SELECT PageVisit_ID ,TargetSite_ID FROM [B].Datawarehouse.mi.ctb_PageEvent WITH (NOLOCK) these two tables from two servers. I need to update targetsite_id in [A].Datawarehouse.mi.ctb_PageEvent records from [B].Datawarehouse.mi.ctb_PageEvent only matched with above query results. 回答1: Try this DECLARE @SummaryOfChanges TABLE(Change VARCHAR(20)); MERGE INTO [A].Datawarehouse.mi.ctb

VBScript Regex: Match everything except multi-line pattern

守給你的承諾、 提交于 2019-12-24 15:25:06
问题 There is a very similar question to the question I need answered (Regex / Vim: Matching everything except a pattern, where pattern is multi-line?): I need to convert the following Vim regular expression into a VBScript regular expression: :%s/\%(^end\n*\|\%^\)\zs\_.\{-}\ze\%(^begin\|\%$\)// Basically, what I need to do is grab all the text before, between, and after methods (not including the code within the methods). I already have a VBScript regular expression to grab methods and the code

SQL EXCEPT performance

不羁的心 提交于 2019-12-24 02:06:45
问题 I'm trying to use a query similar to the following query to find differences between two tables (the same table in a DEV database vs a TEST database). Each table has ~30K rows and ~5 columns. select field1,field2,field3,field4,field5 from dev.dbo.table1 where field1+field2 in ('string1','string2','string3',...,'string50') except select field1,field2,field3,field4,field5 from test.dbo.table1 where field1+field2 in ('string1','string2','string3',...,'string50') field1 is char(5) and field2 is

DB2 SELECT EXCEPT with WHERE clause

问题 I'm trying to compare two tables in a DB2 database in z/OS using SPUFI to submit SQL queries. I'm doing this by using EXCEPT to see the difference between two SELECT queries. I need to filter the SELECT statement from the first query with a WHERE clause. SELECT KEY_FIELD_1,LOOKUP_FIELD_1 FROM TABLE_1 WHERE FILTER_FIELD = '1' EXCEPT SELECT KEY FIELD_2,LOOKUP_FIELD_2 FROM TABLE_2 I got results back, but it also returned an error -199 Is this because the WHERE clause is not present in the second
