QUESTION
I have a project to do for a Python initiation course, but I am stuck close to the end because of a problem.
My problem is the following one : I want to use a double of my "tdata" data frame composed of the values of the different attributes of a class called "world" to make changes to it. (Trying to do some forecast with the current levels of the indicators) I tried to do it by generating a new data frame "graphdat" which I used in a function to generate a graph.
My problem is that, in the end, my "tdata" array is also modified.
I tried to use graphdat = tdata.copy() , but it returns an AttributeError : 'world' object has no attribute 'copy'.
Anyone would know how I could do it in another way?
Thank you!
...ANSWER
Answered 2021-May-06 at 18:52Since tdata
appears to be an instance of a custom class world
for which copy attribute doesn't exist, you can make a copy of it using methods from copy module:
QUESTION
So I have a form in React JS and I am using Firebase Firestore as a database. I wanted to save data to the database on clicking the submit button. So, I added a event listener, which listens for the submit button. But for some reason the event listener isn't being applied.
The part which isn't working
...ANSWER
Answered 2021-May-04 at 10:28Every time the form is rendered you add an event listener so that when the load
event fires on the window, stuff happens.
This:
- Stacks up lots of duplicate event handlers
- Never fires because the load event happened before the Form was rendered for the first time
In general, never bind event handlers directly to the DOM when using React.
(There are some exceptions, but those are tricky edge cases that usually involve content generated by third party libraries).
If you want a submit event handler, then put it in the form's onSubmit
prop.
QUESTION

...ANSWER
Answered 2021-Apr-19 at 16:17If you have a list of all first names and their corresponding gender, you can generate a hash object. Getting the gender is as simple as passing the first name into the hash. One limitation is this doesn't actually tell you their gender, it's really just a guess.

QUESTION
Can anyone help me with a script that adds gridlines to the first seven columns of a row if the first column in that row is not empty?
Here is the code I'm using - grabbed from an old response to a different question on here that I can't find again. I need to change it from adding borders to all cells that are not empty to the behavior I mentioned above.
...ANSWER
Answered 2021-Apr-09 at 12:23You want to set borders to columns B-H in rows where column A is empty.
Solution:In this case, you can do the following:
- Get a range with first 8 columns and the desired rows (from 50 to 200 in the sample below).
- Retrieve the corresponding values and iterate through them, for example with a forEach loop.
- For each row, check if the first value in the array (column A) is an empty string, and set border for that row with that's the case, setting a new range that includes columns
B-H
but just that specific row.
