create a file in the script using python

python create text file
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.

open('1.txt', 'w')

If 1.txt doesn't exist it will create it. If it does exist it will truncate it.
