如何正确地将图像文件保存到目录？

Question

I need help for a Python Program I started this morning, I'm struggling with two errors, one when launching the program but that doesn't do anything, the program still continues to run, and another one when finishing the saving process.

Here is the entire code, just in case:

First error (at launch)

Second error (at saving process)

Answer 1

Change your code in line 54 to this:

img.save('codes/{}.jpg'.format(qr_name))

Answer 2

You have an error at line 54
Use an f-string for variable to be set into your path
img.save(f'codes/{qr_name}.jpg')
