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。

PS "Loading" problems are caused by resource access or processing problems: hard disk reading speed is slow or bad: Use CrystalDiskInfo to check the hard disk health and replace the problematic hard disk. Insufficient memory: Upgrade memory to meet PS's needs for high-resolution images and complex layer processing. Graphics card drivers are outdated or corrupted: Update the drivers to optimize communication between the PS and the graphics card. File paths are too long or file names have special characters: use short paths and avoid special characters. PS's own problem: Reinstall or repair the PS installer.

A PS stuck on "Loading" when booting can be caused by various reasons: Disable corrupt or conflicting plugins. Delete or rename a corrupted configuration file. Close unnecessary programs or upgrade memory to avoid insufficient memory. Upgrade to a solid-state drive to speed up hard drive reading. Reinstalling PS to repair corrupt system files or installation package issues. View error information during the startup process of error log analysis.

"Loading" stuttering occurs when opening a file on PS. The reasons may include: too large or corrupted file, insufficient memory, slow hard disk speed, graphics card driver problems, PS version or plug-in conflicts. The solutions are: check file size and integrity, increase memory, upgrade hard disk, update graphics card driver, uninstall or disable suspicious plug-ins, and reinstall PS. This problem can be effectively solved by gradually checking and making good use of PS performance settings and developing good file management habits.

The key to feather control is to understand its gradual nature. PS itself does not provide the option to directly control the gradient curve, but you can flexibly adjust the radius and gradient softness by multiple feathering, matching masks, and fine selections to achieve a natural transition effect.

The article introduces the operation of MySQL database. First, you need to install a MySQL client, such as MySQLWorkbench or command line client. 1. Use the mysql-uroot-p command to connect to the server and log in with the root account password; 2. Use CREATEDATABASE to create a database, and USE select a database; 3. Use CREATETABLE to create a table, define fields and data types; 4. Use INSERTINTO to insert data, query data, update data by UPDATE, and delete data by DELETE. Only by mastering these steps, learning to deal with common problems and optimizing database performance can you use MySQL efficiently.

MySQL performance optimization needs to start from three aspects: installation configuration, indexing and query optimization, monitoring and tuning. 1. After installation, you need to adjust the my.cnf file according to the server configuration, such as the innodb_buffer_pool_size parameter, and close query_cache_size; 2. Create a suitable index to avoid excessive indexes, and optimize query statements, such as using the EXPLAIN command to analyze the execution plan; 3. Use MySQL's own monitoring tool (SHOWPROCESSLIST, SHOWSTATUS) to monitor the database health, and regularly back up and organize the database. Only by continuously optimizing these steps can the performance of MySQL database be improved.

The loading interface of PS card may be caused by the software itself (file corruption or plug-in conflict), system environment (due driver or system files corruption), or hardware (hard disk corruption or memory stick failure). First check whether the computer resources are sufficient, close the background program and release memory and CPU resources. Fix PS installation or check for compatibility issues for plug-ins. Update or fallback to the PS version. Check the graphics card driver and update it, and run the system file check. If you troubleshoot the above problems, you can try hard disk detection and memory testing.

PS feathering is an image edge blur effect, which is achieved by weighted average of pixels in the edge area. Setting the feather radius can control the degree of blur, and the larger the value, the more blurred it is. Flexible adjustment of the radius can optimize the effect according to images and needs. For example, using a smaller radius to maintain details when processing character photos, and using a larger radius to create a hazy feeling when processing art works. However, it should be noted that too large the radius can easily lose edge details, and too small the effect will not be obvious. The feathering effect is affected by the image resolution and needs to be adjusted according to image understanding and effect grasp.
