How to solve (admin.E107) The value of 'list_display' must be a list or tuple in Django

Today, we're going to solve one of the Django admin issues, which is:
(admin.E107) The value of 'list_display' must be a list or tuple.

This issue happens when you try to set something except list or tuple for list_display.

For example:

@admin.register(Topics)
class EcoProductAdmin(admin.ModelAdmin):
    list_display = "title"

Output:

<class 'core.admin.EcoProductAdmin'>: (admin.E107) The value of 'list_display' must be a list or tuple.

As I said, to solve this issue, we must set a tuple or list.

List:

@admin.register(Topics)
class EcoProductAdmin(admin.ModelAdmin):
    list_display = ['title']

Tuple:

@admin.register(Topics)
class EcoProductAdmin(admin.ModelAdmin):
    list_display = ('title',)

Note: you must add a comma when you want to display one item.
