如何找出一个单词是否在一行内？

import re

def is_word_in_line(word, line):
    pattern = r'\b{}\b'.format(word)
    match = re.search(pattern, line)
    if match:
        return True
    else:
        return False

def is_word_in_text(word, text):
    lines = text.split('\n')
    for line in lines:
        if is_word_in_line(word, line):
            return True
    return False

# 示例用法
text = '''
This is a sample text.
It contains multiple lines.
We want to check if a word is in a line or not.
'''
word = 'sample'
result = is_word_in_text(word, text)
print(result)  # 输出：True
