删除列表中所有元素，这些元素是python中列表中其他元素的子字符串

Question

我有以下列表：

people = ['John', 'Maurice Smith', 'Sebastian', 'Maurice', 'John Sebastian', 'George', 'George Washington']

您可以注意到，John，Maurice，Sebastian和George是全名（Maurice Smith，{{1}的名称或姓氏}和Jogn Sebastian）。

我想只获得全名。这在python中是否可行？

Answer 1

您可以使用此列表理解删除它们：

[p for p in people if not any(p in p2 for p2 in people if p != p2)]

这会迭代每个人p，然后检查条件：

not any(p in p2 for p2 in people if p != p2)

此内部循环遍历每个人p2（跳过与p相同的情况），并检查p in p2（p是否为子字符串）

Answer 2

# make set of first names from full names
firstnames = set(name.split[0] for name in people if " " in name)

# get names that aren't in the above set
people[:] = (name for name in people if name not in firstnames)
