Python 在 "IN"循环中使用 "IF ELSE"

Question

我有一个元组列表，我在一个简单的 for 循环中循环遍历这些元组，以识别包含某些条件的元组。

    mytuplist = 
    [(1, 'ABC', 'Today is a great day'), (2, 'ABC', 'The sky is blue'), 
     (3, 'DEF', 'The sea is green'), (4, 'ABC', 'There are clouds in the sky')]

我希望它像这样高效且可读:

    for tup in mytuplist:
        if tup[1] =='ABC' and tup[2] in ('Today is','The sky'):
            print tup

上面的代码不起作用，也没有打印任何东西。

下面的代码有效，但非常冗长。我如何使它像上面那样？

for tup in mytuplist:
    if tup[1] =='ABC' and 'Today is' in tup[2] or 'The sky' in tup[2]:
        print tup

Answer 1

您应该使用内置的 any()功能:

mytuplist = [
    (1, 'ABC', 'Today is a great day'),
    (2, 'ABC', 'The sky is blue'),
    (3, 'DEF', 'The sea is green'),
    (4, 'ABC', 'There are clouds in the sky')
]

keywords = ['Today is', 'The sky']
for item in mytuplist:
    if item[1] == 'ABC' and any(keyword in item[2] for keyword in keywords):
        print(item)

打印:

(1, 'ABC', 'Today is a great day')
(2, 'ABC', 'The sky is blue')
