Let’s spend some time getting to know Daniel better!
Can you tell us a little about yourself (hobbies, education, etc):
My name is Daniel Mesejo. I’m a software engineer from Cuba currently living in Spain. I love sharing knowledge, have answered several questions related to Python, pandas, and numpy on StackOverflow, and have occasionally spoken at Python events. I enjoy reading and hiking; a curious fact about me is that I’m Erdos number 3.
Why did you start using Python?
I started using Python in college for some research projects. Once I started, I became obsessed with it. Python makes programming joyful; it gives me the same feeling I had as a kid solving logic puzzles.
What other programming languages do you know, and which is your favorite?
In my daily work, I use JVM-based languages Java, Kotlin, and Groovy. Of those, I prefer Kotlin; for me, it is a mix of Java and Python.
What projects are you working on now?
I want to re-start contributing to open-source projects such as dask, eland, and prefect. I also want to grow the usage of my project: trrex.
Which Python libraries are your favorite (core or 3rd party)?
My favorite libraries are collections, itertools, and operators; the number of things you can get done using only those three libraries is impressive.
How did the trrex package come about?
trrex transforms a list of strings into a regular expression so you can search and replace those words efficiently. I wrote it after reading https://stackoverflow.com/q/42742810/4001592. The question is commonly asked on StackOverflow, so I thought having a library for it might be helpful for others.
What are the top three things you love about trrex?
Its ease of use is just one function with three parameters with a string as the output
The performance of the obtained regular expression pattern matches that of even specialized libraries like flashtext.
It integrates well with other data science libraries: spacy, pandas, regex, scikit-learn.
Ease of use and combining well with others are traits of built-in Python functions, so I’m proud of that fact.
Is there anything else you’d like to say?
For those starting to learn Python and want to use StackOverflow, I suggest you look at https://sopython.com/canon/; it collects pointers to the most common questions. I also encourage everyone to try trrex when using regular expressions for keyword manipulation.
Thanks for doing the interview Daniel!
