Python - 如果包含列表中元组的元素，则仅打印行

Question

I've the following text file:

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

And I only want to extract the lines that contains (World Cup and Football) or ('Playing', 'test ').

For example, based on my text file I only want to extract this:

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

Basically I only want to extract if the line contains the two values from each tuple.

For that I am trying the following code:

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)

But with my code I am having the following error:

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

How can I do this?

Thanks

Answer 1

You can try with combination of any and all :

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

You can check any from the list of words and all from items of the list.

( Testing without file )

# 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)

Output:

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

As mentioned in the comment below, if second element is not tuple, it causes unexpected result. Using test example, following shows error as it is comparing if all characters are same instead of words:

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

You were really close, you just needed one more loop:

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)
