python之os模块（python os模块安装方法）

os模块

一.os使用语句

1.

import  os
print(os.getcwd()) #获取当前执行命令所在的目录

import  os
b_path=r"C:\Users\Administrator.USER-20231114RR\PycharmProjects\untitled8\bao"
py_path=r"C:\Users\Administrator.USER-20231114RR\PycharmProjects\untitled8\bao\mk.py"
bcz_path=r"C:\Users\Administrator.USER-20231114RR\PycharmProjects\untitled8\bao\abcde.py"
new_path=r"E:\az\ss1"
new1_path=r"E:\az\ss2\vv.txt"
# print(os.getcwd()) #获取当前执行语句的目录
# print(os.path.isfile(b_path)) #判断是否一个文件 #False
# print(os.path.isfile(py_path)) #True
# print(os.path.isdir(b_path)) #True判断是否一个目录
# print(os.path.isdir(py_path))#False
# print(os.path.exists(b_path)) #True  判断文件是否存在
# print(os.path.exists(bcz_path)) #False 判断文件是否
# print(os.listdir(b_path)) #显示目录下所有文件或目录
# print(os.path.split(b_path)) # 分割文件名和目录('C:\\Users\\Administrator.USER-20231114RR\\PycharmProjects\\untitled8', 'bao')
# print(os.path.join(b_path,"dd.py")) #拼接路径
# print(os.mkdir(new_path)) # 新建目录
# print(os.rename(new_path,new1_path))#修改目录名
print(os.remove(new1_path)) #删除文件

拓展:

print(os.path.dirname(__file__))#获取包当前包的路径
print(os.path.dirname(os.path.abspath(__file__))) ##获取包当前包的路径
print(os.getcwd()) #获取包当前包的路径
print(os.path.dirname(os.path.dirname(__file__))) #获取当前项目路径
print(os.path.abspath(__file__)) #获取绝对路径
