EOL while scanning string literal

This error occurs when there is an unfinished or unclosed string literal in the code. A string literal is a sequence of characters enclosed in quotes (either single or double quotes).

For example, the following code will result in this error:

print('Hello, world!)

This is because the string literal 'Hello, world!' is not closed with a closing quote. To fix this, we need to add a closing quote:

print('Hello, world!')

Another common reason for this error is when there is a line break or a special character (like a tab or a newline) within the string literal that is not properly escaped.

For example:

print('Hello, 
world!')

This will result in the same error because the string literal 'Hello,' is not properly closed before the line break. To fix this, we can either use a backslash to escape the line break:

print('Hello, \
world!')

Or we can use triple quotes to create a multi-line string:

print('''Hello, 
world!''')
