Python实现删除列表中满足一定条件的元素示例

for i in listObj:
  if(...):
    listObj.remove(i)

a = [1, 2, 3, 12, 12, 5, 6, 8, 9]
for i in a:
    if i % 2 == 0 and i % 3 == 0:
      a.remove(i)
print(a)

E:\Program\Python>d.py
[1, 2, 3, 12, 5, 8, 9]

a = [1, 2, 3, 12, 12, 5, 6, 8, 9]
b = a[:]
for i in a:
    if i % 2 == 0 and i % 3 == 0:
      b.remove(i)
a = b
print(a)

E:\Program\Python>d.py
[1, 2, 3, 5, 8, 9]

a = ['what', '', '', 'some', '', 'time']
a = [i for i in a if len(i) > 0]
print(a)
b = [1, 2, 3, 12, 12, 5, 6, 8, 9]
b = [i for i in b if not(i % 3 == 0 and i % 2 == 0)]
print(b)

E:\Program\Python>d.py
['what', 'some', 'time']
[1, 2, 3, 5, 8, 9]
