To remove the first occurrence of an element, use list.remove:
>>> xs = ['a', 'b', 'c', 'd']
>>> xs.remove('b')
>>> print(xs)
['a', 'c', 'd']
To remove all occurrences of an element, use a list comprehension:
>>> xs = ['a', 'b', 'c', 'd', 'b', 'b', 'b', 'b']
>>> xs = [x for x in xs if x != 'b']
>>> print(xs)
['a', 'c', 'd']

Usually Python will throw an Exception if you tell it to do something it can't so you'll have to do either:
if c in a:
a.remove(c)
or:
try:
a.remove(c)
except ValueError:
pass
An Exception isn't necessarily a bad thing as long as it's one you're expecting and handle properly.

Not exactly. my_list.clear() empties the list in place, so all references to that list object still point to the same (now empty) list. Assigning my_list = [] creates a brand new list object, which other references to the old list won’t see. Python raises a ValueError. To avoid this, check if the value exists first using the “in” operator: if “apple” in my_list: my_list.remove(“apple”).
