Python - def mkdir - How can I create a directory if it does not exist - 使用python建立資料夾

Python version ：Python 3.6.0 :: Anaconda 4.3.1 (64-bit)
System version ：Windows 10

# create dir
def mkdir(path):
    import os
    if  os.path.exists(path) == False:
        os.makedirs(path)
        print('mkdir:',path)
    elif  os.path.exists(path) == True:
        print('dir already exist:',path)
mkdir(r'E:\download\tmp\test123')

執行結果：

mkdir: E:\download\tmp\test123 or dir already exist: E:\download\tmp\test123
