This article mainly introduces the three methods of class inheritance in the Python tkinter module. It analyzes the implementation methods and related precautions of the three inheritance methods in combination with examples. Friends in need can refer to this article
The example describes three ways of class inheritance in the Python tkinter module. Share it with everyone for your reference, the details are as follows:
There are three ways of tkinter class inheritance.
Remind us to pay attention to the operation methods of these inheritances
1. Inherit object
1. Shop tk .Frame to parent:
Description:
self.rootframe = tk.Frame(parent)<br>tk.Label(self.rootframe)
import tkinter as tk class MyApp(object): def __init__(self, parent): self.rootframe = tk.Frame(parent) self.rootframe.pack() self.setupUI() def setupUI(self): tk.Label(self.rootframe, text='标签').pack() if __name__ == '__main__': root = tk.Tk() MyApp(root) # 注意这句 root.mainloop()
2. Use root directly
Instructions:
self.root = parent<br/>tk.Label(self.root)
##
import tkinter as tk class MyApp(object): def __init__(self, parent, **kwargs): self.root = parent self.root.config(**kwargs) self.setupUI() def setupUI(self): tk.Label(self.root, text = '标签').pack() if __name__ == '__main__': root = tk.Tk() app = test(root) root.mainloop()
2. Inherit tk.Tk
import tkinter as tk class MyApp(tk.Tk): def __init__(self): super().__init__() self.setupUI() def setupUI(self): tk.Label(self, text='标签').pack() if __name__ == '__main__': MyApp().mainloop()
3. Inherit tk.Frame##There are two situations
1 .With parentimport tkinter as tk class MyApp(tk.Frame): def __init__(self, parent=None): super().__init__(parent) self.pack() self.setupUI() def setupUI(self): tk.Label(self, text='标签').pack() if __name__ == '__main__': MyApp(tk.Tk()).mainloop() #MyApp().mainloop() # 也可以这样
Note: self.pack()
import tkinter as tk class MyApp(tk.Frame): def __init__(self): super().__init__() self.pack() self.setupUI() def setupUI(self): tk.Label(self, text='标签').pack() if __name__ == '__main__': MyApp().mainloop()

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

Docker uses Linux kernel features to provide an efficient and isolated application running environment. Its working principle is as follows: 1. The mirror is used as a read-only template, which contains everything you need to run the application; 2. The Union File System (UnionFS) stacks multiple file systems, only storing the differences, saving space and speeding up; 3. The daemon manages the mirrors and containers, and the client uses them for interaction; 4. Namespaces and cgroups implement container isolation and resource limitations; 5. Multiple network modes support container interconnection. Only by understanding these core concepts can you better utilize Docker.

When installing PyTorch on CentOS system, you need to carefully select the appropriate version and consider the following key factors: 1. System environment compatibility: Operating system: It is recommended to use CentOS7 or higher. CUDA and cuDNN:PyTorch version and CUDA version are closely related. For example, PyTorch1.9.0 requires CUDA11.1, while PyTorch2.0.1 requires CUDA11.3. The cuDNN version must also match the CUDA version. Before selecting the PyTorch version, be sure to confirm that compatible CUDA and cuDNN versions have been installed. Python version: PyTorch official branch

In VS Code, you can run the program in the terminal through the following steps: Prepare the code and open the integrated terminal to ensure that the code directory is consistent with the terminal working directory. Select the run command according to the programming language (such as Python's python your_file_name.py) to check whether it runs successfully and resolve errors. Use the debugger to improve debugging efficiency.

Python excels in automation, scripting, and task management. 1) Automation: File backup is realized through standard libraries such as os and shutil. 2) Script writing: Use the psutil library to monitor system resources. 3) Task management: Use the schedule library to schedule tasks. Python's ease of use and rich library support makes it the preferred tool in these areas.

VS Code extensions pose malicious risks, such as hiding malicious code, exploiting vulnerabilities, and masturbating as legitimate extensions. Methods to identify malicious extensions include: checking publishers, reading comments, checking code, and installing with caution. Security measures also include: security awareness, good habits, regular updates and antivirus software.

CentOS Installing Nginx requires following the following steps: Installing dependencies such as development tools, pcre-devel, and openssl-devel. Download the Nginx source code package, unzip it and compile and install it, and specify the installation path as /usr/local/nginx. Create Nginx users and user groups and set permissions. Modify the configuration file nginx.conf, and configure the listening port and domain name/IP address. Start the Nginx service. Common errors need to be paid attention to, such as dependency issues, port conflicts, and configuration file errors. Performance optimization needs to be adjusted according to the specific situation, such as turning on cache and adjusting the number of worker processes.
