However, there are a few ways to check the syntax of a Python script without executing it. You can check the syntax of a python script without executing it by using the command prompt of your operating system. It will show any syntax errors in your code, which is helpful when working on a python script.
So you’re writing a python program, and you want to check its syntax before running it. It’s possible. You can run your script with the command prompt, which will print out some helpful stuff about what’s going on in your code.

Method 01: Use Cmd prompt (Window) to check the syntax of a python script without executing it
Python is a programming language used to write computer programs and scripts. In Python, scripts can be run without being executed, which is one of its main features. It means you can run your program without having to execute it.
The source code:
countries=['pak','us','uae','india','turkey'] count_gr3=filter(lambda x:len(x)<3,countries) list(count_gr3)
The syntax of a Python script is checked by using the python command and checking the syntax of a program by executing it with this command:
Don’t forget the path directory of the file having the .py extension.
This command will check the syntax of your program, but it will not execute it. You can check the syntax of a script by executing it yourself or by using another Python environment or Python Shell that has access to the same script file (for example, if you have saved your script on your computer).
To use this command, type in the code in your Python Environment and save it as a .py extension in your operating system device.
For example, my_script.py in your system directory.
Now change a code bit.
countries=['pak','us','uae','india','turkey'] count_gr3=filter(lambda x:len(x)<3,countri) list(count_gr3)
And pass the python script into the command prompt.
Here it shows the syntax error, just by pressing the Enter button.
Method 02: Use TextEditor and Cmd prompt(Window) for checking the syntax of a python script without executing it
To check the syntax of a script without executing it, open the file in Notepad++ or TextEdit. Then select File > Save As and save the file as a .py file format.
To execute the script, open the Terminal/Command prompt (Window). Type python filename.py and hit Enter. The results should be displayed in the Terminal (window).
If you hit enter and it executes appropriately and returns no error in the following line, then your code has no error.
It will show you that error in the following line if it contains a mistake.
However, there are ways to check the syntax of a Python script without executing it. The simplest way to check if there is a syntax error in the file covered on this page is by using the command prompt of your operating system.
