SyntaxError: EOL while scanning string literal

This error occurs when there is a problem with the syntax of a string literal in Python. "EOL" stands for "end of line", which means that the interpreter has reached the end of a line of code but expected more characters to complete a string.

Here's an example of code that could cause this error:

print('Hello, world!

In this code, the string literal 'Hello, world!' is not properly closed with a closing quotation mark. The interpreter reaches the end of the line and expects more characters to complete the string, but it finds the end of the file instead. This results in a SyntaxError with the message "EOL while scanning string literal".

To fix this error, you can add the missing closing quotation mark:

print('Hello, world!')
