如何在保留Python中的原始间距的同时替换文本？

def replace_text(original_text, old_text, new_text):
    # 使用replace()方法替换文本
    replaced_text = original_text.replace(old_text, new_text)
    return replaced_text

# 示例文本
text = r"""
    Hello,
        This is a sample text.
    Thank you.
"""

# 调用replace_text()函数替换文本
new_text = replace_text(text, "sample", "example")

# 打印替换后的文本
print(new_text)

    Hello,
        This is a example text.
    Thank you.
