SyntaxError: can't assign to function call after switching from scipy to imageio?

Question

Using imageio.imread instead of scipy.misc.imread (because it is depreciated) is giving me an issue. I want to perform something like this but using imageio:

for file_indexes in duplicates[:30]:
try:
    plt.subplot(121), plt.imshow(imread(files_list[file_indexes[1]]))
    plt.title(file_indexes[1]), plt.xticks([]), plt.yticks([])

When I try the following I get the error

File "<ipython-input-18-2b05f47215d7>", line 4
    plt.subplot(121),img = imageio.imread(files_list[file_indexes[1]])
    ^
SyntaxError: can't assign to function call

That's what I've tried:

for file_indexes in duplicates[:30]:
    try:
        plt.subplot(121), img = imageio.imread((files_list[file_indexes[1]]))
        plt.title(file_indexes[1]), plt.xticks([]), plt.yticks([])

In general, I want to replace scipy.misc.imread in the following code with imageio.imread:

for file_indexes in duplicates[:30]:
    try:
    
        plt.subplot(121),plt.imshow(imread(files_list[file_indexes[1]]))
        plt.title(file_indexes[1]), plt.xticks([]), plt.yticks([])

        plt.subplot(122),plt.imshow(imread(files_list[file_indexes[0]]))
        plt.title(str(file_indexes[0]) + ' duplicate'), plt.xticks([]), plt.yticks([])
        plt.show()
    
    except OSError as e:
        continue

What is the right way to use the correct syntax?

Answer 1

The initial error is located here:

plt.subplot(121), img = imageio.imread((files_list[file_indexes[1]]))

Before, there was no assignment, just another simple statement: plt.imshow(...). Now, there's an assigment, which is not allowed in a list of simple statements. To fix this, you'd just need to move

img = imageio.imread(...)

to a separate line.

But, since you only want to switch from the deprecated scipy.misc.imread to imageio.imread, just replace

plt.imshow(imread(...))

with

plt.imshow(imageio.imread(...))
