Python写的创建文件夹自定义函数mkdir()
Python对文件的操作还算是方便的,只需要包含os模块进来,使用相关函数即可实现目录的创建。
主要涉及到三个函数:
1、os.path.exists(path) 判断一个目录是否存在
2、os.makedirs(path) 多层创建目录
3、os.mkdir(path) 创建目录
直接上代码:
def mkdir(path):
# 引入模块
import os
# 去除首位空格
path=path.strip()
# 去除尾部 \ 符号
path=path.rstrip("\\")
# 判断路径是否存在
# 存在 True
# 不存在 False
isExists=os.path.exists(path)
# 判断结果
if not isExists:
# 如果不存在则创建目录
print path+' 创建成功'
# 创建目录操作函数
os.makedirs(path)
return True
else:
# 如果目录存在则不创建,并提示目录已存在
print path+' 目录已存在'
return False
# 定义要创建的目录
mkpath="d:\\qttc\\web\\"
# 调用函数
mkdir(mkpath)
以上是我写好的一个函数,只需要传入你要创建目录的全路径即可。
说明
在以上DEMO的函数里,我并没有使用os.mkdir(path)函数,而是使用了多层创建目录函数os.makedirs(path)。这两个函数之间最大的区别是当父目录不存在的时候os.mkdir(path)不会创建,os.makedirs(path)则会创建父目录。
比如:例子中我要创建的目录web位于D盘的qttc目录下,然而我D盘下没有qttc父目录,如果使用os.mkdir(path)函数就会提示我目标路径不存在,但使用os.makedirs(path)会自动帮我创建父目录qttc,请在qttc目录下创建子目录web。

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

To run Python code in Sublime Text, you need to install the Python plug-in first, then create a .py file and write the code, and finally press Ctrl B to run the code, and the output will be displayed in the console.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Golang is better than Python in terms of performance and scalability. 1) Golang's compilation-type characteristics and efficient concurrency model make it perform well in high concurrency scenarios. 2) Python, as an interpreted language, executes slowly, but can optimize performance through tools such as Cython.
