如果包含列表中元组的元素，则仅打印行。

Question

我有以下文本文件：

We are playing football at World Cup
teste
We are playing football
Playing test 
World Cup Football

我只想提取包含(世界杯和足球)或(“打”，“测试”)的线条。

例如，基于我的文本文件，我只想提取以下内容：

We are playing football at World Cup
Playing test 
World Cup Footbal

基本上，我只想从每个元组中提取包含这两个值的行。

为此，我正在尝试以下代码：

file = 'text.txt'
words = [('Football','World Cup'), ('Playing test ')]
with open(file, "r") as ins:
    for line in ins:
        if all(x in line.lower() for x in words):
            print(line)

但是，对于我的代码，我有以下错误：

TypeError: 'in <string>' requires string as left operand, not tuple

我该怎么做？

谢谢

Answer 1

您可以尝试使用any和all组合。

if any(all(words.lower() in line.lower() for words in word_tuples) for word_tuples in words)

您可以从单词列表和列表中的所有项中检查任何内容。

(没有文件的测试)

# Note: second element needs to be tuple else causes unexpected results
words = [('Football','World Cup'), ('Playing test',)] 
ins = ["We are playing football at World Cup",
       "teste",
       "We are playing football",
       "Playing test",
       "World Cup Football"]

for line in ins:
    if any(all(words.lower() in line.lower() for words in word_tuples) for word_tuples in words):
        print(line)

输出：

We are playing football at World Cup
Playing test
World Cup Football

如下面的注释中所述，如果第二个元素不是元组，则会导致意外的结果。使用测试示例，如果所有字符都是相同的，而不是单词，则在比较时将显示错误：

x = "test palying"
if all(w.lower() in x for w in words[1]):
    print("ERROR")

你真的很亲密，你只需要再循环一次：

file = 'text.txt'
words = [('Football','World Cup'), ('Playing test ')]
with open(file, "r") as ins:
    for line in ins:
        for tup in words:
            if all(word.lower() in line.lower() for word in tup):
                print(line)
