问题 I want to add some comments in presentation file for some text-boxes. Is there any python-pptx attribute available to do that ? 回答1: PowerPoint comments are not yet supported in python-pptx . There's not really a feature request for that at the time of this writing, so you can feel free to add one if you like. 回答2: Recommended reading : https://python-pptx.readthedocs.io/en/latest/user/text.html https://python-pptx.readthedocs.io/en/latest/user/quickstart.html Hope this helps, 来源： https:/

问题 I'm trying to set up a SQLite table where the rowid starts from 0 instead of the default 1. The end goal is to be able to run the first INSERT statement and have it insert to rowid 0. Explicitly setting rowid to 0 for that first INSERT is not an option. I've tried a few things related to AUTOINCREMENT but am not having any luck getting this to work cleanly. The only successful way I've found is to insert a row with rowid of -1 and then delete it later. This works but it's messy and I'd like

问题 I'm writing some code for a program that will be able to run some software, read the inputs/outputs and do some data processing along the way. For example: (this is not the real case, but just to give an idea) class MusicFile(object): extension = [""] def setup(self): #set up the data def runsoftware(self): #play the song class MP3(MusicFile): extension = [".mp3"] def setup(self): #setupMP3file def runsoftware(self): #runMP3software I have about 4 general classes, and then file extensions

问题 I need to group a Pandas dataframe by date, and then take a weighted average of given values. Here's how it's currently done using the margin value as an example (and it works perfectly until there are NaN values): df = orders.copy() # Create new columns as required df['margin_WA'] = df['net_margin'].astype(float) # original data as str or Decimal def group_wa(): return lambda num: np.average(num, weights=df.loc[num.index, 'order_amount']) agg_func = { 'margin_WA': group_wa(), # agg_func

问题 I can parse the following data. but I cannot show it as a table in columnar. How can I chart this? for item in items: print(item['symbol']) [ {"symbol": "ZILUSDT", "positionAmt": "0", "entryPrice": "0.00000", "markPrice": "0.01728152", "unRealizedProfit": "0.00000000", "liquidationPrice": "0", "leverage": "20", "maxNotionalValue": "25000", "marginType": "cross", "isolatedMargin": "0.00000000", "isAutoAddMargin": "false", "positionSide": "SHORT"}, {"symbol": "FLMUSDT", "positionAmt": "0",

问题 I am currently working with a Windows XP Computer at my school. My question is on how to find the exact path variable to run Python in the command line. I have tried multiple directories but they all keep displaying "'python' is not recognized as an internal or external command, operable program or batch file." Is there an easy way to find this? 回答1: If the installation is ok. You can use python, opening the command prompt window and navigating to your Python installation directory (default
