I need to make a code that removes the first occurrence of an given element in a list. So far I have only managed to make the code remove every occurrence of the given element.

Her is my code rigth now:

currently i have this code in numpy 1.19.5 and i don't know how to remove the [ '']

I'm scraping a website that has a table of satellite values (https://planet4589.org/space/gcat/data/cat/satcat.html).

Because every entry is only separated by whitespace, I need a way to split the string of data entries into an array.

However, the .split() function does not suit my needs, because some of the data entries have spaces (e.g. Able 3), I can't just split everything separated by whitespace.

It get's trickier, however. In some cases where no data is available, a dash ("-") is used. If two data entries are separated by only a space, and one of them is a dash, I don't want to include it as one entry.

e.g say we have the two entries "Able 3" and "-", separated only by a single space. In the file, they would appear as "Able 3 -". I want to split this string into the separate data entries, "Able 3" and "-" (as a list, this would be ["Able 3", "-"]).

Another example would be the need to split "data1 -" into ["data1", "-"]

Pretty much, I need to take a string and split it into a list or words separated by whitespace, except when there is a single space between words, and one of them is not a dash.

Also, as you can see the table is massive. I thought about looping through every character, but that would be too slow, and I need to run this thousands of times.

Here is a sample from the beginning of the file:

I want to test the URL http://example.com in a browser window for an empty search string, i.e http://example.com/search/?s=, but not match anything like /search/?s=withsearchterms that has any search terms after the /search/?s=, and then use an if statement and .addClass to display a div that warns that no search terms were entered.

I'm trying to use Javascript and g.test like below; the RegEx pattern is valid, according to several RegEx testers. But no luck:

I have a loop function called removeand wish to show every loop result of removing only the ith character of the string. Let say I have a string "hello", and the expected output of the loop function is shown below:

The objective is to make it so that all uppercase letters are printed out in a string, however, I must keep the bool function and use it within my code. I have resolved some issues from the past but ran up with a issue that is preventing me from fixing it. Test cases are "HEllO" -> "HEO" "my" -> "" "NAME" -> "NAME" "Is" -> "I" "AnDeRsON" -> "ADRON".

I can't get how to write regexp right to be able match only heo. So for example if we found some l char during parsing - cancel that match then.

I need to map some categorical values to integers. I tried the solution from this link at In[24]:
