How do I check the existing file with same name in the directory and use python to rename new files to save?

Question

I am using plt.savefig to save a plot generated by matplotlib.pyplot, and I want to save my figure with different names each time I run the code. How can I do that?

Does this answer your question? How to save multiple graph in directory with unique file name in python? — wovano

The easiest would probably be to use the current time, if you don't save multiple files per second.

import datetime

ts = datetime.datetime.now().strftime("%Y%m%d-%H.%M.%S")
plt.savefig(f"figure-{ts}.png")
