Using list comprehension or simple looping will be able to remove the list from the list and create a new one in Python.
The list comprehension can remove all occurrences by creating a new list with all elements except the specified list.
Example remove the list from the list in Python
In simple example code, where we have a and b lists, the new list should have items that are only in the list a.
Using a list comprehension that tells us quite literally which elements need to end up in new_list:
a = ['apple', 'carrot', 'lemon']
b = ['pineapple', 'apple', 'tomato']
new_list = [fruit for fruit in a if fruit not in b]
print(new_list)Output:
Another example
Using a for loop and append method.
a = ['apple', 'carrot', 'lemon']
b = ['pineapple', 'apple', 'tomato']
new_list = []
for fruit in a:
if fruit not in b:
new_list.append(fruit)
print(new_list)Output: [‘carrot’, ‘lemon’]
