从同一行中提取以特定字符开头的字符串

def extract_strings(lines, prefix):
    result = []
    for line in lines:
        if line.startswith(prefix):
            result.append(line)
    return result

# 示例用法
lines = [
    "Hello, world!",
    "Good morning!",
    "Hi there!",
    "Hey, how are you?",
    "Hello, everyone!"
]
prefix = "Hello"

extracted_strings = extract_strings(lines, prefix)
print(extracted_strings)

['Hello, world!', 'Hello, everyone!']
