Python is a statically typed language. This means that the way the code is written is strict.

If you forget to complete a block of code in your code, you will get an error like "Syntax error: Unexpected EOF during analyzes". This happens in a number of situations, for example when you forget to add a line of code in a for loop.

In this guide, we talk about this Python error and why it is being raised. Let’s take a look at some sample scenarios so that you can understand how to fix this common error.

SyntaxError: Unexpected EOF while scanning

The "SyntaxError: Unexpected EOF while scanning" error occurs when the end of the source code is reached before not all code is executed. This happens when you make an error in the structure or syntax of your code.

EOF stands for End of File. Represents the last character of a Python program.

Python reaches the end of a file before executing each block of code if:

I forgot to wrap your code in a special statement such as a for loop, a while loop, or a function.
Do not close all parentheses on a line of code in your program.

Let’s go through each of these errors one by one. There are other scenarios where this error is generated, but the ones mentioned above are the most common.

Example n. 1: Include the code in a special declaration

For Loops , if statements , while loops and functions require at least one line of code in their instructions. Forgetting to include a line of code in a special instruction will result in an unexpected EOF error.

Check out the for loop which prints a list of ingredients in a recipe:

We define a called "ingredients" which stores a list of ingredients for a vanilla shortbread recipe. We use a for loop to iterate through each ingredient in the list. Run our code and see what happens:

We haven’t added any code in our "for" loop . This raises an error. This same error occurs if we define a while loop, if statement, or function without including any code in the statement.

To solve this problem, let’s add some code to our cycle. Let’s add a print () statement so that we can print each ingredient to the console:

Let’s run our code:

Our code prints each ingredient in our ingredient list. This tells us that the code blocks have completed successfully.

If not if you want to add code in a special declaration, use the declaration " pass " as a placeholder. Consider this code:

This code does not return any value. We have def terminated a loop, but the "pass" instruction tells our program that the loop has nothing to do yet. This keyword is often used when developers create the framework for a program. Once the structure of a program has been determined, the "pass" instructions are replaced by the corresponding code.

Example no. 2: parentheses not closed

An " Unexpected EOF while parsing" error occurs when you forget to close all parentheses on a line of code.

Write a program that prints the recipe information to the console. Start by defining a few variables with information about a recipe:

We format it as a string using the .format () method:

The {} values ‚Äã‚Äãare replaced with their respective values ‚Äã‚Äãin the .format () statement. This means that our string will say:

Execute our code:

On our print ( ) line of code, we close a single set of v brackets and open two sets of brackets. Therefore, an error was returned.

We solve this problem by adding a final parenthesis (")") at the end of the line of code print ():

This line of code ends with two brackets instead of one. All parentheses are now closed.

Let’s try to run our code again:

Our code is working fine.

This same error occurs if you forget to close a dictionary using {} brackets. This error occurs even if you forget to close a list using parentheses [].

Conclusion

The "Syntax Error: Unexpected EOF during Parse" error is generated when the Python interpreter reaches the end of a program before each line of code has been executed.

To resolve this error, first verify that each if statement, for loop, while loop, and function contains code. Second, be sure to close all parentheses in your code.
