You probably meant if str(row[1]) == "Y":.

Comparison in Python is done with a double equals (==).

If I may intervene, your code would be much better off using enumerate() like so:

Use addAll() to add all elements of ArrayList into another ArrayList

You are almost correct, issue is that the length of your array is 0 (you can verify it with length(candidates)), so Julia complains when you are trying to set non-zero indexed elements of an array with candidates[i]. If you do not know length of your array in advance, then you should use push! function.

This is unrelated to airflow or tweepy.

This issue is specific to Mac OS High Sierra and above. https://stackoverflow.com/a/52230415/4434664 solved my issue.

Basically, airflow test merely runs the task in-process, but the scheduler would start a worker process which would call fork(), and apparently, High Sierra introduced some new security changes that's breaking fork() usages in python.

This also caused problems in ansible. Refer https://github.com/ansible/ansible/issues/32499#issuecomment-341578864

This is a simple approach that converts the txt output data into a data structure (that can easily be written into a csv file).

The basic idea is using data structures along with the amount of headers / columns in order to parse entry sets from the one liner txt output.

Have a look at the code comments, every "TODO 4 U" means work for you, mostly because I cannot really guess what you need to do at those positions in the code (like how to get the headers).

This is just a main method that does its work straight forward. You may want to understand what it does and apply changes that make the code meet your requiremtens. Input and output are just Strings that you have to create, receive or process yourself.

The problem is that the rogue library never accounted for the case where no matches are found for your regular expression. The line in the rogue source code id = match.groups(0)[0] is the problematic one. If you look this up in the documentation it says the groups function Return a tuple containing all the subgroups of the match, from 1 up to however many groups are in the pattern.... Because no matches where found, an empty tuple was returned, and the code is trying to grab the first item from an empty tuple which results in an error.

If dorms(Dorms) fails, then certainly csMusic(Music) will fail because it requires dorms(Dorms) to succeed.

One way to find the problem is to try commenting out some clues and then run the query dorms(Dorms). You'll find that you get multiple solutions. Eventually you'll find one clue that causes failure. Of course, that might not be the bad clue.

Another thing that might be wrong is the use of "not". For example, if you run this query:

Here is the logic that you can use, where the script will wait for max 30 for the Data menu item and if the element is present with in 30 seconds it will click on the element.
