Program description : Lapindrome is defined as a string which when split in the middle, gives two halves having the same characters and same frequency of each character. If there are odd number of characters in the string, we ignore the middle character and check for lapindrome. For example gaga is a lapindrome, since the two halves ga and ga have the same characters with same frequency. Also, abccab, rotor and xyzxy are a few examples of lapindromes. Note that abbaab is NOT a lapindrome. The two halves contain the same characters but their frequencies do not match. Your task is simple. Given a string, you need to tell if it is a lapindrome.

My code :

Suppose I have the following graph

I have an excel file which I regularly update in Power BI.

I added an additional line, which did not cause any issues to my operations, however, Power BI also added three "null" lines afterwards.

I do not understand why.

I thus created a table, because I thought that I would prevent this.

But I still have "null" rows appended to my lines.

The only remedy that I found is to filter rows on a column (Lapin) which as no null (and which should never in future), in the following way:

I expected to get two list that contains all males in one and all females in another list. I am just getting a list with only one item.

Using Python2.7

Output: ['Phyllis Lapin'] ['Roy Anderson']

Expected Output :['Phyllis Lapin', 'Pam Beesly', 'Angela Martin' etc..]

------------------------['Dwight Shrute','Jim Halpert','Ryan Howard' etc..]

"Select the beers that have been drank by more than one person". Basically, I'm trying to retrieve a query result that shows me the list of the beers that has been drank by more than one person and then the name of the persons who have drank that beer. I tried to do a group and having clause but realized that I cant have a group clause since I'm interested in duplicate values from both the name and beer columns. What should I do?

I'm using a service called opentok which store video on their cloud and give me a callback url when file are ready so that i can download it and store on my cloud provider.

We use gcloud where we work and i need to download the file, then store it on my gcloud bucket with a firebase cloud functions.

Here is my code :

The aim is to select all the names of the persons who have drank all beers from tyskland. In this case, im looking to find the name of the person that has max(count) of beers from germany. I formed smaller tables along the way to try to get the result: From the table below :

Ive been looking around different sites and havent found any examples om how to join different tables when looking for a result while including a except statement in the query. To know the structure of such a query would be very helpful! Lets say I want to find the names of the people who havent drank the beer Anchor Steam Beer, how should the query operation look like?

My own attempt looked like this:

Im trying to find the person who has drank most beer types from USA. The result should be just be the name of that person alone and not include a count column. How should I perform the select statement? The result should look like this:
