create a file in the script using python
python create empty file
python read and write to same file
python write variable to file
python read file line by line
python overwrite file
python append to file
python parse text file
I am new to python.
I wanted to know if I could create a text file in the script itself before writing into. I do not want to create a text file using the command prompt.
I have written this script to write the result into the file
with open('1.txt', 'r') as flp: data = flp.readlines()
however I know that 1.txt has to be created before writing into it.
Any help would be highly appreciated.

If you were to save it to a local .py file named python_script.py. There are many ways to do that: Create a Python script from command line and save it ; Create a Python script using a text editor or IDE and save it ; Saving a Python script from a code editor is pretty easy.
You can use open() to create files. Example:
This will create the file if it doesn't exist yet, and will append to it if the file already exists.
In this tutorial, I'll show you the steps to create a batch file to run a Python script using a simple example. But before we dive into the example, here is the batch The easiest way to simply create a file without truncating it in case it exists is − open('my_file.txt', 'a').close() In Python 3.4+, you can directly use the pathlib module to touch files. For example, from pathlib import Path Path('my_file.txt').touch() You can also create new files without opening them using the os module.
Using open(filename, 'w') creates the file if it's not there. Be careful though, if the file exists it will be overritten!

Python too supports file handling and allows users to handle files i.e., to read Note: The file is created in the same directory of the script if no path is specified. Open can be used in a several modes, in your case you have opened in read mode ('r'). To write to a file you use the write mode ('w').
