            In your function, you are returning nothing. So it makes your ethusdt_macd NoneType because it is basically nothing.

            So, when you call to_excel method, it cannot find it because ethusdt_macd is None.

            You need to return the data1 (or whatever variable you need) in your function.

            Typescript class method return type based on parameter
            Asked 2022-Feb-22 at 11:37

            I am trying to create a class with a method whose return type will depend on the boolean value of a flag-parameter

            I have managed to do this successfully when

            • using a plain function expression that implements an interface,
            • or in a class when declaring the method overloads directly in the class body

            However, I am not able to do this when I am trying to use an interface that is implemented by the class.

            I would like to do this using interface implementation for a class method to achieve the dynamic return type.

            Thanks!

            I don't think you get a choice but to repeat the overload in the class (as you did with Exp) when implementing the interface; here's a modified Exp2 that both implements the interface and lists the overloads:

            You can use ROW_NUMBER() to identify the rows you want (the first one of each group). Then filtering out is easy.

            Asked 2022-Feb-16 at 15:41

            I have a database with MANY out-of-date file locations. The difference between the out-of-date file locations and the correct locations is simply the left-side of the address. So, I am attempting to take the left-side off and replace it with the correct string. But, I can't get there because my query is altering the right-side of the address.

            OK this is tricky, I did some Foxpro 20 years ago but don't have it to hand.

            Your SELECT statement looks OK to me. In the comments under the question Thomas G created this DbFiddle which shows that in a 'normal' dbms, your SELECT statement gives the result you are expecting: https://dbfiddle.uk/?rdbms=sqlserver_2017&fiddle=37047d2b7efb91aaa029fa0fb98eea24

            So the problem must be something FoxPro/dBase specific rather than a problem with your SELECT statement.

            Reading up I see people say that with FoxPro always use ALLTRIM() when using RIGHT() or LEN() on table fields because the data gets returned padded with spaces. I don't see how that would cause the exact bug you're seeing but you could try this maybe:

            Creating new DF column based on average values from specific columns identified in second DF
            Asked 2021-Sep-08 at 16:59

            I apologize as I prefer to ask questions where I've made an attempt at the code needed to resolve the issue. Here, despite many attempts, I haven't gotten any closer to a resolution (in part because I'm a hobbyist and self-taught). I'm attempting to use two dataframes together to calculate the average values in a specific column, then generate a new column to store that average.

            I have two dataframes. The first contains the players and their stats. The second contains a list of each player's opponents during the season.

            What I'm attempting to do is use the two dataframes to calculate expected values when facing a specific opponent. Stated otherwise, I'd like to be able to see if a player is performing better or worse than the expected results based on the opponent but first need to calculate the average of their opponents.

            My dataframes actually have thousands of players and hundreds of matchups, so I've shortened them here to have a representative dataframe that isn't overwhelming.

            The first dataframe (df) contains five columns. Name, STAT1, STAT2, STAT3, and STAT4.

            The second dataframe (df_Schedule) has a Name column but then has a separate column for each opponent faced. The df_Schedule usually contains different numbers of columns depending on the week of the season. For example, after week 1 there may be four columns. After week 26 there might be 100 columns. For simplicity sake, I've included just five columns ['Name', 'Opp1', 'Opp2', 'Opp3', 'Opp4', 'Opp5'].

            Using these two dataframes I'm trying to create new columns in the first dataframe (df). EXP1 (for "Expected STAT1"), EXP2, EXP3, EXP4. The expected columns are simply an average of the STAT columns based on the opponents faced during the season. For example, Edgar faced Ralph three times, Marc once and David once. The formula to calculate Edgar's EXP1 is simply:

            ((Ralph.STAT1 * 3) + (Marc.STAT1 * 1) + (David.STAT1 * 1) / Number_of_Contests (which is five in this example) = 100.2

            Answered 2021-Jul-03 at 17:51

            If you select all the buttons at the beginning, you're binding the function to all of them.

            Instead, you need to find each button as a child of the card element in your foreach. At that point, you assign to the only result button (inside that specific card element) the first listener and to the only back button the other listener.

            Fixed snippet below, I only edited the javascript part.

            Side note: When you use querySelector or querySelectorAll and you want to access something by its id, like a css rule, you need to specify # first. Like you're doing for css classes where you use . as prefix.
