Hey there! That SyntaxError: unexpected EOF while parsing is happening for a super straightforward reason: your final with statement doesn’t have any code inside it.

In Python, anytime you use a colon (:) to start a code block (like with with, if, for, etc.), you have to follow it with indented lines of code that belong to that block. Right now, your line:

with open('myfile.txt',mode='a') as p:

ends with a colon and nothing comes after it. Python hits the end of your script without finding the indented code it expects, hence the EOF error.

Fix Option 1: Add code to use the append-mode file #

If you intended to write to the file in append mode, just add an indented line (or lines) that interact with the p file object. For example:

%%writefile mynewfile.txt
L stands for Lamborghini
M stands for Maserati
A stands for Audi

with open('myfile.txt', mode = 'r') as newfile:
    print(newfile.read())

# Now the with block has actual code to execute
with open('myfile.txt',mode='a') as p:
    p.write("\nP stands for Porsche")  # Appends this line to myfile.txt

Fix Option 2: Remove the unused with statement #

If that last with line was a leftover from testing and you don’t actually need it, just delete it entirely. There’s no reason to open a file if you’re not going to use it.

Either fix will resolve that syntax error—just make sure every colon in your code is followed by an indented code block.
