Python: Simplify variable declaration (with a for loop ?)

Question

I'm new to python and I have declared some variables in my code but they are almost similar, I would like to know if it is possible to simplify this with a for loop or the like so as not to have 10 lines of declaration?

Left_10 = PhotoImage(file = 'image_10.jpg')
Left_9 = PhotoImage(file = 'image_9.jpg')
Left_8 = PhotoImage(file = 'image_8.jpg')
Left_7 = PhotoImage(file = 'image_7.jpg')
Left_6 = PhotoImage(file = 'image_6.jpg')
Left_5 = PhotoImage(file = 'image_5.jpg')
Left_4 = PhotoImage(file = 'image_4.jpg')
Left_3 = PhotoImage(file = 'image_3.jpg')
Left_2 = PhotoImage(file = 'image_2.jpg')
Left_1 = PhotoImage(file = 'image_1.jpg')

Thanks for your help

don't do that. use proper data structure. Check http://stupidpythonideas.blogspot.com/2013/05/why-you-dont-want-to-dynamically-create.html — buran, Jun 08 '21 at 07:24

Use a dict:

Left = {i: PhotoImage(file = 'image_'+str(i)+'.jpg') for i in range(1,11)}

and access with Left[7]

This is basically a copy of what @Julien said, but as a list instead of a dict:

Left = [PhotoImage(file=f"image_{i}.jpg") for i in range(1, 11)]

And you can access them by index and sort them (unlike the dict): Left[0] # PhotoImage with file=image_1.jpg...
