1. Prepare the installation package
1) Go to the python official website to download the python operating environment (https://www.python.org/downloads/), currently compared The stable one is python-3.5.2
2) Go to the pycharm official website to download the latest version of the IDE (http://www.jetbrains.com/pycharm/download/#section=windows). The official website provides mac, There are three versions of windows and linux. I downloaded pycharm-community-2016.2.3.exe

2 .Install the software
1) Install the python operating environment
Double-click python-3.5.2.exe
Generally use custom installation comparison Okay, otherwise the automatic installation will install the environment into the personal directory, which is sometimes very troublesome to find. In addition, mark the check mark in front of the second red box, otherwise you need to manually add the python installation path to the path of the Windows environment variable
Manually modify the installation path here, you can install it to the C drive or the D drive
Complete the installation
Then we open CMD, enter python in it, and then we can directly enter the encoding
We can enter print('hello world!') to test it python runs, as shown below
The above is the detailed content of What is the python operating environment?. For more information, please follow other related articles on the PHP Chinese website!

The methods to debug the shebang problem include: 1. Check the shebang line to make sure it is the first line of the script and there are no prefixed spaces; 2. Verify whether the interpreter path is correct; 3. Call the interpreter directly to run the script to isolate the shebang problem; 4. Use strace or trusts to track the system calls; 5. Check the impact of environment variables on shebang.

Create multi-dimensional arrays with NumPy can be achieved through the following steps: 1) Use the numpy.array() function to create an array, such as np.array([[1,2,3],[4,5,6]]) to create a 2D array; 2) Use np.zeros(), np.ones(), np.random.random() and other functions to create an array filled with specific values; 3) Understand the shape and size properties of the array to ensure that the length of the sub-array is consistent and avoid errors; 4) Use the np.reshape() function to change the shape of the array; 5) Pay attention to memory usage to ensure that the code is clear and efficient.
