python创建文件夹

函数形式

def mkdir(path):
    isExists = os.path.exists(path)
    if not isExists:
        os.makedirs(path)
        print('Directory create successfully!')
        return True
    else:
        print('Directory already exists!')
        return False

save_dir = 'D:/Project_QF/Amyloid_search/data/potential/amyloid_structure/'
mkdir(save_dir)

或者直接使用系统函数

判断目录是否存在

import os
dirs = 'D:/Project_QF/Amyloid_search/data/input/'

if not os.path.exists(dirs):
    os.makedirs(dirs)

判断文件是否存在

import os
filename = 'D:/Project_QF/Amyloid_search/id/contact_potential.txt'

if not os.path.exists(filename):
    os.system(r"touch {}".format(path))
