# 获取上上层目录
print(os.path.dirname(os.path.dirname(os.getcwd()))) # /Users/na/PycharmProjects/python_1test



from pathlib import Path

# 获取上一层目录
print(Path.cwd().parent) # /Users/na/PycharmProjects/python_1test/a

# 获取上上层目录
print(Path.cwd().parent.parent) # /Users/na/PycharmProjects/python_1test

# 获取绝对路径-->目录
print(Path().cwd())  # /Users/na/PycharmProjects/python_1test/a/c
