Welcome to the lesson on Python File Write
Python File Write
Write to an Existing File
To write to an existing file, you must add a parameter to the open() function:
"a" - Append - will append to the end of the file
"w" - Write - will overwrite any existing content
Example: Open the file "StudyPython.txt" and append content to the file:
Example: Open the file "StudyPython2.txt" and overwrite content to the file:
the "w" method will overwrite the entire file.
Creating a new file
To create a new file in Python, use the open() method, with one of the following parameters:
"x" - Create - will create a file, returns an error if the file exist
"a" - Append - will create a file if the specified file does not exist
"w" - Write - will create a file if the specified file does not exist
Example: Create a file called "StudyPython.txt":
file = open("StudyPython.txt", "x")
Result: a new empty file is created!
Example: Create a new file if it does not exist:
file = open("StudyPython.txt", "w")
