How to Fix SyntaxError: Invalid Syntax When Using Command Line in Python
We can use Python with the command line to run files, manage packages, and more. To run a file, we redirect to the given directory where the file is present, run the command prompt, and use the python filename.py command to run the script.
This tutorial will discuss the file "<stdin>", line 1 SyntaxError: invalid syntax error when using the command line in Python.
SyntaxError: invalid syntax When Using the Command Line in Python
Not Running the Command in the Command Prompt
This error is raised when we try to run a Python script using the Python shell; we use a Python shell to type and execute commands. To run a file, we need to use the command prompt, as discussed earlier.
The following code is an example of this error.
python filename.py
Output:
file "<stdin>", line 1 SyntaxError: invalid syntax
The only way to fix this error is to run this line of code in the command prompt. We must redirect to the directory where the file is stored and run the command prompt.
We need to execute this command, which will run the code in the filename.py script file.
Environment Variables Are Not Set Properly
Another reason behind this error can be due to the environment variables. We set the environment variables so the command prompt can identify and run Python commands.
This error can occur if the environment variables are not set properly.
To set the environment variables, we should follow these simple steps.
-
First, right-click the
This PCicon on the desktop and select thePropertiesoption. -
Then, we need to select the
Advanced Settingsmenu and theEnvironment Variablesoptions, which will take us to theEnvironment Variablewindow. -
Here, we need to add the directory of the Python executable to the
PATHvariable for the User. -
If the error persists, we can create a new variable named
Pythonand add the directory here.
This should help in resolving the error.
