Tweet-counter: A module to calculate the length of a tweet

Posted to: DEV; Hacker News; Twitter

I just published a new Python package: tweet-counter (repo).

If you want to automate posting of tweet using Python, it’s pretty important to know if your tweet exceeds the 280-character limit.

It turns out, working this out is non-trivial, as Twitter has a few rules around how it count’s characters. These are basically:

To it’s credit, Twitter provides official open-source libraries for calculating tweet length.

But there isn’t a library for Python that I could find. So I made one. It’s probably far from perfect, but it does at least take into account the top two conditions, which should cover most common English-language use cases.

$ pip3 install tweet-counter
$ count-tweet "Otters 👪 otters 𝗼𝘁𝘁𝗲𝗿𝘀 otters"

I’m hoping to use it in an automatic tool for turning blog posts into twitter threads that I’m working on.
