Why I cannot apply .remove() method to list in python?
Question:
Actual code:
my_list = ['a', 'b', 'c']
no_c_list = my_list.remove('c')
print(no_c_list)
The expected output is:
[‘a’, ‘b’]
But in reality, I’m getting None:
What I’m doing wrong and what should I do to remove the item from the list?
Answers:
remove() does not return anything. Or, perhaps to be more precise, it returns None. You’re removing 'c' from the my_list and then setting the no_c_list to None.
my_list = ['a', 'b', 'c']
my_list.remove('c')
print(my_list)
You are using the .remove() function incorrectly. The remove() function removes the element from the my_list, it doesn’t create a new list that doesn’t have the element. Try this
my_list = ['a', 'b', 'c']
my_list.remove('c')
print(my_list)
Actual code:
my_list = ['a', 'b', 'c']
no_c_list = my_list.remove('c')
print(no_c_list)

[‘a’, ‘b’]
