How do you remove a string and an integer from a set of lists together
states = [
'ACTIVE',
['red', 'green', 'blue'],
'CANCELLED',
'FINISHED',
5,
]
states.remove(5)
Also to delete 'green' from the list

states.remove(5, 'green')
You can use slice if the elements are next to each other for instance
del states[3::]
['ACTIVE', ['red', 'green', 'blue'], 'CANCELLED']
still not really solving your needs
The only way I can think of doing this is to create your own function
def remove_items(states, remove_list): # function to remove multiple items
for i in states: # iterate through the list
if isinstance(i, list): # is the item in the list a list?
remove_items(i, remove_list) # if yes call the remove_items function on that list
if i in remove_list: # if the item is in the remove_list
states.remove(i) # remove item
return states # return the list
if __name__ == '__main__':
states = [
'ACTIVE',
['red', 'green', 'blue'],
'CANCELLED',
'FINISHED',
5,
]
remove_list = ['CANCELLED', 'blue']
print(remove_items(states, remove_list))
This may come in handy if you do not know beforehand what is in the list !!!
Hopefully of some use.
