Python迭代器/一行for循环

Question

这可能是显而易见的，但我被困在是否可以使用迭代器/一行来实现以下目标:

TEAMS = [u'New Zealand', u'USA']
dict = {}

我怎么写:

for team in TEAMS:
    dict[team] = u'Rugby'

作为迭代器，例如:

 (dict[team] = u'Rugby' for team in TEAMS) # Or perhaps
 [dict[team] for team in TEAMS] = u'Rugby

可以做到吗?括号应该放在哪里?

所需输出:

dict = {u'New Zealand': u'Rugby', u'USA': u'Rugby'}

我知道python中有很多与迭代器相关的问题，所以我很抱歉，如果这有一个答案，我试着寻找，无法找到一个很好的答案。

Answer 1

您可以使用字典推导。请看下面:

TEAMS = [u'New Zealand', u'USA']
d = {team: 'Rugby' for team in TEAMS}

Answer 2

使用dict fromkeys方法。另外，不建议使用关键字dict作为变量名，改为d而不是

TEAMS = [u'New Zealand', u'USA']
d = {}.fromkeys(TEAMS, u'Rugby')
# d = {u'New Zealand': u'Rugby', u'USA': u'Rugby'}

Answer 3

for team in TEAMS:
    dict.update({team: u'Rugby'})

Answer 4

TEAMS = [u'New Zealand', u'USA']    
dict(zip(TEAMS, ['Rugby'] * 2))
