Capitalize words in string except for ones in quote-CodePudding

I want to capitalize keywords in a list of strings except for keywords that are in quote.

let's say you have

list1 = ["I like bananas", "he likes 'bananas' and apples", "we like bananas and apples"]
list2 = ["bananas", "apples"]

the output I'd want is

>>> ["I like BANANAS", "he likes 'bananas' and APPLES", "we like BANANAS and APPLES"]

CodePudding user response：

You can use regular expression to check if the phrase in list2 is surrounded by quotes or not:

import re

In [ ]: re.sub(rf"(?<!')\bbananas\b(?!')", "BANANAS", "I like bananas")
Out[ ]: 'I like BANANAS'

In [ ]: re.sub(rf"(?<!')\bbananas\b(?!')", "BANANAS", "I like 'bananas'")
Out[ ]: "I like 'bananas'"

You can create function to replace all patterns in list2:

def capitalize(s, pats):
     for pat in pats:
         s = re.sub(rf"(?<!')\b{pat}\b(?!')", pat.upper(), s)
     return s

In [ ]: [capitalize(s, list2) for s in list1]
Out[ ]:
['I like BANANAS',
 "he likes 'bananas' and APPLES",
 'we like BANANAS and APPLES']

This is what I have

for sentence in list1:
    for keyword in list2:
        if keyword in sentence:
            start_index = sentence.index(keyword)
            if not start_index != 0 or not sentence[start_index-1] == "'":
                sentence = sentence[:start_index]   keyword.upper()   sentence[start_index   len(keyword):]
    print(sentence)
