Can someone to extract in specific group of words from each line-CodePudding

i have list which has the following words stored . How Can i seperate the sentence inside the [ and ] for example in dash[0] what i need to sperate is The Sunday Profile: Panth meets Wealth from the rest. I want to do that in each group and store it . -

dash = ['{"Headlines": ["The Sunday Profile: Panth meets Wealth"]}\n', '{"Headlines": ["Wage no bar"]}\n']

i have tried-

 for line in f:
    text = line
            
    

print(text)

but that prints only the last line

from ast import literal_eval
dash = ['{"Headlines": ["The Sunday Profile: Panth meets Wealth"]}\n', 
'{"Headlines": ["Wage no bar"]}\n']
for i in dash:
    print(literal_eval(i)["Headlines"])

I would recommend that in the future you follow StackOverflow's guidance on asking a good question. You should also be sure to provide a minimal, reproducible example.

With that said, assuming the values in the dash list are always json and there is always one headline, you could use a list comprehension to get a new list of all headlines.

import json

dash = ['{"Headlines": ["The Sunday Profile: Panth meets Wealth"]}\n', '{"Headlines": ["Wage no bar"]}\n']

headlines = [json.loads(x)["Headlines"][0] for x in dash]

The new variable headlines would have all of the items you are looking for. If Headlines from the dash list can have more than one value, I'd recommend just leaving them as lists and dropping the [0] index from the stated solution.

Create a function that converts the string to a dictionary and returns the first item of the value

import json
def get_first_item(s):
    return json.loads(s).values()[0][0]

Then map the function to the list

for line in map(get_first_item, dash):
    print(line)

gives

The Sunday Profile: Panth meets Wealth
Wage no bar
