1.当前路径及路径下的文件
os.getcwd():查看当前所在路径。
os.listdir(path):列举目录下的所有文件。返回的是列表类型。
#-*-coding:utf-8-*- import os print (os.getcwd()) print (os.listdir(os.getcwd())) E:\python36\python3.exe E:/pj/request3/test2.py E:\pj\request3 ['.idea', 'data.ini', 'data1.ini', 'request3.iml', 'sqlConnectionPool.py', 'sqldb.py', 'test.py', 'test1.py', 'test2.py', 'test3.py', '__init__.py', '__pycache__'] Process finished with exit code 0
2.绝对路径
os.path.abspath(path):返回path的绝对路径。
#-*-coding:utf-8-*- import os print (os.path.abspath(".")) print (os.path.abspath(".."))
3.查看路径的文件夹部分和文件名部分
os.path.split(path):将路径分解为(文件夹,文件名),返回的是元组类型。os.path.join(path1,path2,...):将path进行组合,若其中有绝对路径,则之前的path将被删除。
#-*-coding:utf-8-*- import os print (os.path.split(r"D:\pj\request1\test_report\result18-06-0419-41-23.html")) print (os.path.join(os.path.abspath('.'),'test2.py')) E:\python36\python3.exe E:/pj/request3/test2.py ('D:\\pj\\request1\\test_report', 'result18-06-0419-41-23.html') E:\pj\request3\test2.py Process finished with exit code 0
os.path.dirname(path):返回path中的文件夹部分,结果不包含'\',os.path.basename(path):返回path中的文件名。
#-*-coding:utf-8-*- import os print (os.path.dirname(r"D:\pj\request1\test_report\result18-06-0419-41-23.html")) print (os.path.basename(r"D:\pj\request1\test_report\result18-06-0419-41-23.html")) E:\python36\python3.exe E:/pj/request3/test2.py D:\pj\request1\test_report result18-06-0419-41-23.html Process finished with exit code 0
4.查看文件时间
os.path.getmtime(path):文件或文件夹的最后修改时间,从新纪元到访问时的秒数。
os.path.getatime(path):文件或文件夹的最后访问时间,从新纪元到访问时的秒数。
os.path.getctime(path):文件或文件夹的创建时间,从新纪元到访问时的秒数。
#-*-coding:utf-8-*- import os print (os.path.getmtime(r"D:\pj\request1\test_report\result18-06-0419-47-56.html")) print (os.path.getatime(r"D:\pj\request1\test_report\result18-06-0419-47-56.html")) print (os.path.getctime(r"D:\pj\request1\test_report\result18-06-0419-47-56.html")) E:\python36\python3.exe E:/pj/request3/test2.py 1528112894.4665465 1528112895.0270474 1528112876.6849978 Process finished with exit code 0
5.查看文件大小
os.path.getsize(path):文件或文件夹的大小,单位字节
#-*-coding:utf-8-*- import os print (os.path.getsize(r"D:\pj\request1\test_report\result18-06-0419-47-56.html")) E:\python36\python3.exe E:/pj/request3/test2.py 2860859 Process finished with exit code 0
6.查看文件是否存在
os.path.exists(path):文件或文件夹是否存在,返回True 或 False。
#-*-coding:utf-8-*- import os print (os.path.exists(r"D:\pj\request1\test_report")) print (os.path.exists(r"D:\pj\request1\test_report1")) print (os.path.exists(r"D:\pj\request1\test_report\result18-06-0419-47-56.html")) print (os.path.exists(r"D:\pj\request1\test_report\result18-06-0419-47-561.html")) E:\python36\python3.exe E:/pj/request3/test2.py True False True False Process finished with exit code 0
7.实例说明
在自动化测试过程中,常常需要发送邮件,将最新的测试报告文档发送给相关人员查看,这是就需要查找最新文件的功能。
#-*-coding:utf-8-*-import osfiles={}times=[]path=r'D:\pj\request1\test_report'filelist=os.listdir(path)for file in filelist: time=os.path.getmtime(os.path.join(path,file)) times.append(time) files[time]=filetimes.sort()#print (times)filelist=[]for time in times: filelist.append(files[time])print (filelist)
E:\python36\python3.exe E:/pj/request3/test2.py ['result18-06-0419-41-23.html', 'result18-06-0419-42-08.html', 'result18-06-0419-47-56.html', 'result18-06-0419-48-14.html', 'result18-06-0514-37-14.html'] Process finished with exit code 0
