How to Run Python Code in CMD: Techniques to Improve Your Python Skills

Learn how to run Python code in CMD and improve your coding skills with various commands and techniques, including starting Python shell, running Python scripts, executing shell commands in Python, and more.

Python is a popular programming language that is used by developers to create a variety of applications, ranging from web applications to data analysis tools. Python can be executed on various platforms, including the command prompt. Running Python code in the command prompt can increase productivity and efficiency. In this blog post, we will learn how to run python code in the command prompt and explore various commands and techniques to improve our Python coding skills.

Starting Python Shell in Command Prompt

To start the Python shell in the command prompt, open the command prompt and type “python”. This will initiate the Python shell. You can check if Python works by typing “python” and hitting enter. You can exit the Python shell by typing “Ctrl+Z” and hitting enter.

You can also use the “py command” to give a Python script to the Python interpreter. This command can be used to execute a Python script directly from the command prompt.

Running Python Scripts in Command Prompt

To run a Python script from the command prompt, navigate to the file location in the command prompt and type “python filename.py”. This will execute the Python script. The default Python interpreter on Windows is referenced using the command “py”. You can use the command “py -V” to check the version of Python installed on your system.

If you want to stop a running script, you can use the “Ctrl+C” command. This will stop the execution of the Python script.

Running Shell Commands in Python

You can run shell commands in Python by using the “os.system()” command. This command can be used to run simple shell commands. For instance, you can use the command “os.system(’dir’)” to list the files and folders in the current directory in the command prompt.

You can also use the “subprocess.run()” command to execute a program or call a system command. This command provides more control and flexibility than the “os.system()” command.

Running Python as Admin in Command Prompt

To run Python as an administrator in the command prompt, you need to create a shortcut for python.exe. Right-click on the python.exe file and select “Create Shortcut”. Then, right-click on the shortcut and select “Properties”. In the Properties dialog box, select the “Shortcut” tab and click the “Advanced” button. Check the box next to “Run as administrator” and click “OK”. Click “Apply” and “OK” to close the dialog boxes.

You can now run Python as an administrator by clicking on the shortcut and selecting “Run as administrator”.

Advanced Techniques in Python

There are several advanced techniques that you can use to improve your Python skills. One of these techniques is to use virtual environments to manage dependencies and isolate projects. Virtual environments allow you to create a separate environment for each project, which can help prevent conflicts between different Python packages.

You can also use an IDE like PyCharm or Visual Studio Code to write and run Python code. These IDEs provide advanced features like code completion, debugging, and syntax highlighting, which can help you write better code.

Jupyter Notebook is another advanced technique that you can use for data analysis and visualization. Jupyter Notebook is an open-source web application that allows you to create and share documents that contain live code, equations, visualizations, and explanatory text.

Finally, you can learn Python libraries like NumPy, Pandas, and Matplotlib for data science. These libraries provide advanced features for data analysis and visualization, which can help you build better data analysis tools.

To create a requirements file for your project, you can use the “pip freeze > requirements.txt” command. This command will create a requirements file that contains a list of all the packages installed in your virtual environment. You can use the “pip install -r requirements.txt” command to install all the required packages for your project.

Whether you’re writing Python code on your Windows PC or just want to use existing Python scripts, it’ll be helpful to learn how to run code from the Command Prompt. Running Python code is easy—you’ll just need to have Python installed. This wikiHow article will walk you through opening a Python file from Command Prompt, and teach you how to fix the common «python is not recognized as an internal or external command» error.

Finding the Python File Path

• You can copy the location by highlighting it (click and drag your mouse across the «Location» value) and then pressing Ctrl + C .

Running a Python File

• For example, to open a Python file in a folder named «Files» on your Desktop, you would enter cd desktop/Files here.
• If you copied the path to the file, you can type in cd and a space and then press Ctrl + V to paste in the path.

• For example, if your Python file is named «script», you would type in python script.py here.
• If your Python file has one or more spaces in its name, you’ll place quotation marks around the file name and extension (e.g., python «my script.py» ).

• If you encounter an error that says ‘python’ is not recognized as an internal or external command after pressing Enter, you’ll need to add Python to the PATH list before retrying this part.

Adding Python to the PATH List

• Click This PC on the left side of the File Explorer.
• Double-click your hard drive in the «Devices and drives» section.
• Scroll down and double-click the «Users» folder.
• Double-click the folder with your username on it.
• Scroll down and double-click «AppData».
• Double-click «Local».
• Scroll down and double-click «Programs».
• Double-click the «Python» folder.
• Double-click the Python folder with your preferred version number (e.g., «Python36»).

Copy the path to the Python folder. Click once the address bar at the top of the File Explorer to highlight its contents, then press Ctrl + C to copy the highlighted address.

Click System info . This is a link in the upper-right corner of the window. Doing so opens the System Information window.

Click the Advanced system settings link. You’ll see this in the upper-left side of the System Information window. Yet another window will pop up.

• You may have to scroll up or down with your mouse cursor hovering over the «User variables» pane to find the «Path» variable.

Click New . It’s on the right side of the window. A text field will open in the middle of the window.

Paste in your copied path. Press Ctrl + V to do so. Your copied path will appear in the text field in the middle of the window.

Click OK on the three open windows. This will save your changes and close the «Path» window, the «Environmental Variables» window, and the «System Properties» window.

Community Q&A

I want to create a shortcut that executes the utility «ptpython,» running in the cmd prompt. The shortcut I have points to the directory containing «ptpython.exe» file but it does not execute it.

It sounds like ptpython.exe is a command-line utility, meaning it will only start if you execute it from a DOS window — you can’t create a shortcut for it directly. You can probably create a shortcut to cmd.exe, though (the DOS window) and pass it the ptpython.exe file as a parameter. Something like «cmd.exe /c ptpython.exe» should work, or if this disappears in the end, try with /k (instead of /c).

Yes. The directions to access the environment variables would be slightly different, as there is no «Power User» menu in Windows 7. Instead: 1. Press the Windows key and R to open the Run dialog. 2. Enter «sysdm.cpl». 3. Click the «Advanced» tab of the System Properties Window. 4. Click the «Environmental variables». Most everything else would work as described even on Windows 95 (if there’s a version of Python for Windows 95).

Запуск файла Python из командной строки Windows

В этой статье мы рассмотрим, как запустить файл Python с помощью командной строки в Windows. Это поможет вам выполнять ваш код Python, не открывая его в интерпретаторе или редакторе кода. Давайте приступим!

Для запуска файла Python в командной строке, у вас должен быть установлен Python. Если вы до сих пор этого не сделали, то вы можете воспользоваться нашем руководством: Установка Python на Windows.

Как открыть командную строку Windows

Для начала нам необходимо открыть командную строку Windows. Это можно сделать зажав одновременно клавиши WIN + R, в открывшемся окне введите «cmd» и нажмите клавишу Enter.

О других способах открытия командной строки, мы писали ранее в нашей статье.

Как перейти в директорию с файлом Python

Для запуска файла Python нам необходимо перейти в командной строке в директорию, где находится данный файл.

Для этого вы можете использовать команду cd (change directory). Например, если ваш файл Python находится в директории «C:\my_python_files», вы можете ввести команду «cd C:\my_python_files». После этого вы будете находиться в этой директории и готовы к запуску файла Python.»

Если ваш файл Python находится на другом диске, то вам необходимо сначала сменить диск в командной строке. Для этого вы можете ввести название диска, например, «D:», и нажать Enter. Затем вы можете использовать команду «cd», как в примере выше.

Более подробно о команде «cd» вы можете узнать из нашей статьи.

Запуск файла Python

После того, как в командной строке вы перешли в директорию, где находится ваш файл, вы можете использовать команду ‘python .py’, чтобы запустить файл. Например, если ваш файл называется ‘hello_world.py’, вы можете ввести ‘python hello_world.py’, чтобы запустить этот файл. После чего файл будет исполнен.
