1. Open idle. Click file, then click new file. This creates a new file.
After creating a new file, we enter the first line of code and use the print function to print a sentence on the screen. The string must use double quotes and the input method must use English. Input method, if symbols are entered using the Chinese input method, an error will occur. print("Let's do a calculation problem of adding two integers!")
Similarly, print the second sentence on the screen to interact with the user and remind the user Enter the first number.
The third line calls the input function and assigns the content entered by the user to a. At this time, a receives string information, so the next step is to convert the string. is an integer. This enters instructions for the computer to process the data.
Then follow the above steps to write the second addend and the final output sum. Note that when the last sentence prints the result, the quotation marks are in string form, and x y is a numerical value. form, so you need to add a comma in the middle. If you do not add a comma, an error message will be prompted. The above is the completion of all program writing. The next step is to save, name, and run. As shown in the figure
The running results are as follows:

You can manage different Python versions by using pyenv, venv and Anaconda. 1) Use pyenv to manage multiple Python versions: install pyenv, set global and local versions. 2) Use venv to create a virtual environment to isolate project dependencies. 3) Use Anaconda to manage Python versions in your data science project. 4) Keep the system Python for system-level tasks. Through these tools and strategies, you can effectively manage different versions of Python to ensure the smooth running of the project.

The impact of homogeneity of arrays on performance is dual: 1) Homogeneity allows the compiler to optimize memory access and improve performance; 2) but limits type diversity, which may lead to inefficiency. In short, choosing the right data structure is crucial.
