python目录判断与创建

Posted 2020-10-20

1、完成目录判断
2、完成文件创建
3、完成cpickle模块化写与读

import cPickle as p,os

dirlis = os.getcwd()
    dirlis_new = dirlis + "\\"+"pytTest"
    print dirlis_new
    if not os.path.exists(dirlis_new):
        os.mkdir(dirlis_new)
        print "目录创建成功！！！"
    else:
        print "目录已经存在！！！"
    os.chdir(dirlis_new)
    print "进入目录，开始新建文件"
    file_name = "python.py"
    with open(file_name,"w") as fo:
        fo.write("#coding=utf-8")
    #p.dump(open(file_name),True)
    f1 = file("tem.pkl","a")
    p.dump("\nprint \"wgood\" ",f1,True)
    f1.close()
    fr = file("tem.pkl","r")
    ar = p.load(fr)[1]
    print ar
