Replace all dots except the one between quotes in Python-CodePudding

I want to split news based on sentence and I encounter this problem. How do I replace all dot except the one between direct sentence using iteration or regex? Thanks

Input

Anna said "I want to eat. But I am not hungry.". She is a weird person.

Output

Anna said "I want to eat. But I am not hungry." \n She is a weird person \n

CodePudding user response：

One trick we can try uses re.sub with the regex pattern ".*?"|\.\s*. This will first match a quoted term, and afterwards will only match dot which is not quoted. Then, we use a lambda expression in the callback we only replace the dot match with newline.

inp = 'Anna said "I want to eat. But I am not hungry.". She is a weird person.'
output = re.sub(r'".*?"|\.\s*', lambda m: '\n' if m.group().strip() == '.' else m.group(), inp)
print(output)

This prints:

Anna said "I want to eat. But I am not hungry."
She is a weird person

CodePudding user response：

strings = 'Anna said "I want to eat. But I am not hungry.". She is a weird person.'
output = ""
for i, string in enumerate(strings.split("\"")):
    if i%2 == 0:
        string = string.replace('.', '\n')
    else:
        string = "\""   string   "\""
    output = output   string
print(output)

This gives:

Anna said "I want to eat. But I am not hungry."

She is a weird person
