How to create a new text file using Python

I'm practicing the management of .txt files in Python. I've been reading about it and found that if I try to open a file that doesn't exist yet it will create it on the same directory from where the program is being executed. The problem comes that when I try to open it, I get this error:

IOError: [Errno 2] No such file or directory:
'C:\Users\myusername\PycharmProjects\Tests\copy.txt'.

I even tried specifying a path as you can see in the error.

import os

THIS_FOLDER = os.path.dirname(os.path.abspath(__file__))
my_file = os.path.join(THIS_FOLDER, 'copy.txt')

Looks like you forgot the mode parameter when calling open, try w:

with open("copy.txt", "w") as file:
    file.write("Your text goes here")

The default value is r and will fail if the file does not exist

'r' open for reading (default)
'w' open for writing, truncating the file first

Other interesting options are

'x' open for exclusive creation, failing if the file already exists
'a' open for writing, appending to the end of the file if it exists
