通过字符串从特定行提取一组值

def extract_values_from_specific_line(input_string, line_number):
    lines = input_string.split('\n')  # 按行分割字符串
    specific_line = lines[line_number - 1]  # 获取特定行的内容

    # 使用正则表达式提取值
    import re
    pattern = r'\b[A-Za-z]+\b'  # 假设需要提取的值是由字母组成的单词
    values = re.findall(pattern, specific_line)

    return values

# 示例用法
input_string = '''
Line 1: This is the first line.
Line 2: This is the second line.
Line 3: This is the third line.
'''
line_number = 2
values = extract_values_from_specific_line(input_string, line_number)
print(values)  # 输出: ['This', 'is', 'the', 'second', 'line']
