如何在python 3中打开仅用于追加的文件

# 打开文件并追加内容
file_path = "path/to/file.txt"  # 文件路径
content = "This is the appended content."  # 要追加的内容

with open(file_path, "a") as file:
    file.write(content)

# 关闭文件
file.close()

# 打开文件并追加内容
file_path = "path/to/file.txt"  # 文件路径
content = "This is the appended content."  # 要追加的内容

with open(file_path, "a+") as file:
    file.write(content)

    # 读取文件内容
    file.seek(0)  # 将文件指针移动到文件开头
    file_content = file.read()
    print(file_content)

# 关闭文件
file.close()
