Python computer version software functions
1.Python software is powerful and fast
Python covers everything from asynchronous processing to compressed files, and the language itself is flexible and powerful enough to handle any problem domain. Build your own web server with three lines of code. Build flexible data-driven code using Python's powerful and dynamic introspection capabilities and high-level language features like metaclasses, duck typing, and decorators. Python allows you to quickly write the code you need. And, thanks to the highly optimizing byte compiler and support libraries, Python code runs fast enough for most applications.
2.Python software is user-friendly and easy to learn
The Python newsgroup is known as one of the friendliest. An enthusiastic community of developers and users maintains a wiki, hosts international and local conferences, runs development sprints, and contributes to the online code repository.
Python also comes with complete documentation, both integrated into the language and separate web pages. Online tutorials are targeted at both experienced programmers and novice programmers. All designed to get you to production quickly. The availability of top-notch books completes the study package.
3.Python core programming software is open
The Python core programming software implementation is under an open source license, making it free to use and distribute, even for commercial use. The Python software is licensed through the Python Software Foundation.

How to run py file in python
python runMethod one:
1. When installing python, there will usually be an interactive interpreter, as shown in the figure:
2. Open the Python interactive interpreter and enter the test code.
3. If you close it directly, the code you just wrote will be lost. At this time, you need to create a new text document, write print 'hello world', and then rewrite the file name as: hello.py.
4. Open the python interpreter, click [file] at the top, click [open] in the pop-up options, select the file you just saved, and click [Open].
5. After opening, the code you just wrote will be displayed.
6. Click [Run] in the menu bar and click [run module] in the pop-up options, or press F5 directly to run the code, as shown in the figure below, the operation is successful and the results are printed.
python runMethod two:

img=data.camera()
arr=img.flatten()
4. Use the following instructions to generate and draw a histogram.
plt.figure("hist")
n, bins, patches = plt.hist(arr, bins=256, normed=1,edgecolor='None',facecolor='red') plt.show()
5. You can see the generated histogram
