Writing to file in Python - GeeksforGeeks
1 week ago - Before writing to a file, let’s first understand the different ways to create one. Creating a file is the first step before writing data. In Python you control creation behaviour with the mode passed to open() (or with pathlib helpers). Note: You can combine flags like "wb" (write + binary) or "a+" (append + read).

Every time you enter and exit the with open... block, you're reopening the file. As the other answers mention, you're overwriting the file each time. In addition to switching to an append, it's probably a good idea to swap your with and for loops so you're only opening the file once for each set of writes:
with open("output.txt", "a") as f:
for key in atts:
f.write(key)

You need to change the second flag when opening the file:
wfor only writing (an existing file with the same name will be erased)aopens the file for appending
Your code then should be:
with open("output.txt", "a") as f:

Any text editor; although there are specialty editors called IDEs like Pycharm that are made to assist in writing code. Once you have a text file containing your script, you give it to the Python Compiler/Interpreter (python), and it compiles then runs your code.
