有沒有一種簡單的方法能夠按值刪除列表元素？ - Is there a simple way to delete a list element by value?

問題：

a = [1, 2, 3, 4]
b = a.index(6)

del a[b]
print a

The above shows the following error: 上面顯示瞭如下錯誤：

Traceback (most recent call last):
  File "D:\zjm_code\a.py", line 6, in <module>
    b = a.index(6)
ValueError: list.index(x): x not in list

So I have to do this: 因此我必須這樣作：

a = [1, 2, 3, 4]

try:
    b = a.index(6)
    del a[b]
except:
    pass

print a

But is there not a simpler way to do this? 可是，沒有簡單的方法能夠作到這一點嗎？
