using remove

Question

list=["a","b","c","a"]
list.remove("a")
this removes only the first a, I want to remove both. How ?

Answer 1

You could do:

for i, letter in enumerate(list) :
if letter=='a':
del list[i]

Answer 2

list = [x for x in list if x!="a"]

By the way it is very bad to call your variable 'list' because you override the builtin function. Use my_list or whatever else you want.

Answer 3

Good question
