I'm making a simple Word Builder type of game (where one player enters a word, and the other player enters a word starting with the last letter of the first player's word), and I can't get the Text to show up on both the screens. I'm able to get the text to show up if I hard code it, like:

The partition_filter argument in wr.s3.read_parquet() is failing to filter a partitioned parquet dataset on S3. Here's a reproducible example (might require a correctly configured boto3_session argument):

Dataset setup:

I have this exercise:

Write a recursive function that takes a string and returns all the characters that are not repeated in said string.

The characters in the output don't need to have the same order as in the input string.

First I tried this, but given the condition for the function to stop, it never evaluates the last character:

Given two strings, determine if they share a common substring. A substring may be as small as one character.

Example:

According to this blog by the author of DataFrames.jl the following line of code should work select(df, :name => ByRow(split) => [:firsname, :lastname]). However, I got an error.

Do I overlook something here?

I have two dataframes of different sizes. They both have four columns: Words, x, y and z.

However, when joining these two dataframes, I want to keep the values of x, y, z of the words that are similar. The words that doesn't exist in df1 but exist in df2 are kept.

I tried to use pd.merge but this will keep the two values and only similar words. And if I use pd.concat I have to drop similar elements, but will not be from the first data frame.

I need to produce a hash value for a given word. the hash value need to be deterministic, or the same value for the same word, however if the given word has an different cases the hash value changes. So my objective is to convert the given word (const char) to a lower case witin the hash function, in order to obtain always the same hash code regardless the case. I have the following code:

I have a trivial R script that works nicely:

newbie here. Apologies in advance if I don't use the proper terminology.

SITUATION: I'm working with my first SQL database, and the cells in one column have multiple values, many of which overlap with other cells. Here's an excerpt (I'm new to stack overflow and can't insert images yet, and I can't figure out the best way to represent the layout in text, but here's my best attempt):
