python获取当前路径，当前路径上级目录，当前路径上上级目录

python目录操作

#当前文件的目录
current_path = os.path.dirname(os.path.realpath(__file__))
current_path1 = os.getcwd()
#输出：E:\PycharmProjects\path_test\path_test_1

#当前文件的目录的上级目录
#第一种方式
superior_path = os.path.dirname(os.path.dirname(__file__))
#第二种方式
superior_path1  = os.path.abspath(os.path.join(current_path, ".."))
#输出：E:/PycharmProjects/path_test

#当前文件的上上级目录
s_path = os.path.abspath(os.path.join(current_path, "../.."))
#输出 E:\PycharmProjects

#路径拼接
splicing_path = os.path.join(s_path , 'path_test\path_test_1')
#输出：E:\PycharmProjects\path_test\path_test_1
