Jupyter notebook progressbar

I have this rather handy wee piece of code I'd like to share: a Jupyter notebook Progress bar.

When will the PDB run out of 4-letter codes?

The PDB ids are really nice and short: 4 letter codes. But when will all the combinations run out? Actually, not for a long long time.
The current total is 155,618 structures and new ones are added at a rate of 12000 structures per year, which means that, assuming a constant growth, in 125 years —(36 ^ 4 - 155,618 ) /  12,000 —the PDB will finish codes to allocate.
2145. That is a few years after the setting of Kim Robinson's New York 2140, where New York is a flooded super-Venice, so I am guessing the RCSB PDB, in San Diego, will have long been flooded so lack of 4-letter codes is not top of their concerns.
