问题 I want to connect an API with Excel through Excel VBA. The API requires a public/private keypair with RSA-SHA1 signature. I have used openssl to generate the pair, uploaded the public key to the API's services and have the private part stored on my local computer. Now I want to connect with my API so I will sign my request. But VBA does not have native RSA-SHA1 signing. I have found the following code at https://en.wikibooks.org/wiki/Visual_Basic_for_Applications/String_Hashing_in_VBA which

问题 I need to insert a timestamp with milliseconds in an Oracle table with Python 3.6 and cx_Oracle 6.4.1. The insert is done okay but I am losing the milliseconds on the way. The timestamp is passed as a datetime object. Any ideas how I could keep the milliseconds without making a to_timestamp() in the SQL itself? I would like to keep passing a datetime in the SQL transaction. I use executemany() as the idea is to insert multiple records at once. import cx_Oracle import datetime conf = {

问题 I am currently trying to scrape a dynamic website which uses javascript to provide information after hovering over images. I am trying to obtain the data inside of the text containers brought up by hovering over these images, but am having difficulty doing so because when I define all of the elements, then attempt to create a loop which hovers over all of them, I only receive the text data from the first element I defined, over and over as many elements as there are (10 on this page.) Here is

问题 I do not know if this is actually possible, but I think it' s worth a try to find out. There are maybe other and better patterns (if you know one let me know, I will look them up) to do this, but I'm just curious to know if this is possible. When you have to call an API you could do it directly from within the controller using the HttpClient like this: [Authorize] public async Task<IActionResult> Private() { //Example: get some access token to use in api call var accessToken = await

Thanks Chris 回答1: If the caret is in a window created by another thread, you need to call AttachThreadInput.

问题 I am trying to apply a rolling function, with a 3 year window, on a pandas dataframe. import pandas as pd # Dummy data df = pd.DataFrame({'Product': ['A', 'A', 'A', 'A', 'B', 'B', 'B', 'B'], 'Year': [2015, 2016, 2017, 2018, 2015, 2016, 2017, 2018], 'IB': [2, 5, 8, 10, 7, 5, 10, 14], 'OB': [5, 8, 10, 12, 5, 10, 14, 20], 'Delta': [2, 2, 1, 3, -1, 3, 2, 4]}) # The function to be applied def get_ln_rate(ib, ob, delta): n_years = len(ib) return sum(delta)*np.log(ob[-1]/ib[0]) / (n_years * (ob[-1]

问题 I have very simple Python function that subtracts scalar value from pandas Series: def sub(x: pd.Series, a: int) -> pd.Series: return x - a It works as expected. I'm using type hints to enable type checker directly in my PyCharm IDE. The issue here is I get this warning message: Expected type 'Series', got 'int' instead As you can see in the image below: I understand that Python is dynamically typed language so in some cases type checking with type hints has its own limitations. But this
