python如何删除list

L = [1,2,2,3,4,5,6,7,8,9]

del L[0],L[3:6]

print(L)

>>>[2, 2, 3, 7, 8, 9]

#注意上面的操作，是先删除L[0]之后重新排序

L = [1,2,3]

del L

print（L)

错误：name 'L' is not defined,#表示已经被删除

L = [1,2,2,3,4,5,6,7,8,9]

a = L.pop(2)

print(L)

print(a)

>>>[1, 2, 3, 4, 5, 6, 7, 8, 9]

>>>2

L = [6,7,8,9]

L.pop()

print(L)

[6, 7, 8]

    L = [1,2,2,3,4,5,6,7,8,9]

    L.remove(2)

    print(L)

    >>>[1, 2, 3, 4, 5, 6, 7, 8, 9]

L.remove(2)

print(L)

>>>[1, 3, 4, 5, 6, 7, 8, 9]
