PYTHON: Is there a simple way to delete a list element by value?

 python - Is there a simple way to delete a list element by value? - Stack Overflow

To remove an element's first occurrence in a list, simply use list.remove

:

>>> a = ['a', 'b', 'c', 'd']
>>> a.remove('b')
>>> print(a)
['a', 'c', 'd']

Mind that it does not remove all occurrences of your element. Use a list comprehension for that.

>>> a = [10, 20, 30, 40, 20, 30, 40, 20, 70, 20]
>>> a = [x for x in a if x != 20]
>>> print(a)
[10, 30, 40, 30, 40, 70]
