Old matplotlib animation now fails

Some years ago I created a Python program that reads GPS data and creates an animation stored in an mp4 file. Not very elegant but it worked. Not very original as it was based on the example found here: https://shorturl.at/dTCZZ Last time it worked was about a year ago. Since then I have moved to

Re: Two aces up Python's sleeve

Hi, In Java its possible to work this way with the Integer datatype, just call Integer.valueOf(). I am not sure whether CPython does the same. Because it shows me the same behaviour for small integers that are more than only in the range -128 to 128. You can try yourself: Python 3.14.0a1 (tags

This only works for small integers. I guess this is because tagged pointers are used nowadays ? For large integers, also known as bigint, it doesn't work: Python 3.13.0a1 (tags/v3.13.0a1:ad056f0, Oct 13 2023, 09:51:17) >>> x, y = 5, 4+1 >>> id(x) == id(y) True >>> x, y = 10**200, 10**199*10 >>
