小玩意 文件夹创建

import os
r = os.path.dirname(__file__)
b = 'task'
os.mkdir(r+'/'+b)
a = ['bin','db','lib','config','log']
for i in a:
    os.mkdir(r+'/'+b+'/'+i)

　　

嵌套文件夹创建
import os
r = os.path.dirname(__file__)
a = 'Blank'
Blank= os.mkdir(r + '/' + a )

b = ['Client','Manage','Server']

Client = ['config','lib',]
Manage = ['config','lib',]
Server = ['bin','config','db','log','lib',]

for i in b:
    if i == b[0]:
        os.mkdir(r +'/'+ a + '/' + i)
        for i1 in Client:
            os.mkdir(r +'/'+a+'/'+i+'/'+i1)
    elif i == b[1]:
        os.mkdir(r +'/'+ a + '/' + i)
        for i1 in Manage:
            os.mkdir(r +'/'+a+'/'+i+'/'+i1)
    elif i ==b[2]:
        os.mkdir(r +'/'+ a + '/' + i)
        for i1 in Server:
            os.mkdir(r +'/'+a+'/'+i+'/'+i1)
