How to export qr_code img to disk?

Question

I generate a qr code image from an url using the python package qrcode:

url='www.google.com'
qr = qrcode.QRCode(version=1,
                   error_correction=qrcode.constants.ERROR_CORRECT_L,
                   box_size=10,
                   border=4)

qr.add_data(url)
qr.make(fit=True)
img = qr.make_image()
return img

How do I save the img to the disk at a certain path ?

I tried:

image_file = open(path_qr_code, 'w')
image_file.write(img)
image_file.close

but I get:

TypeError: write() argument must be str, not PilImage

Hint: "Not PIL Image", then you can search "how to save an PIL Image to disk". — Geno Chen

TypeError: write() argument must be str, not PilImage

This indicates that img has type PilImage, then you can use the way saving a PilImage to save it. For example,

img.save(path_qr_code)
