Python, how to create an empty file

⭐️ 👀 2023 WEB DEVELOPMENT BOOTCAMP starting in days! Join the waiting list to reserve your spot in my 10-weeks cohort course and learn the fundamentals, HTML, CSS, JS, Tailwind, React, Next.js and much much more! 👀 ⭐️

To create a file, use the open() global function.

It accepts 2 parameters: the file path, and the mode.

You can use a as the mode, to tell Python to open the file in append mode:

file = '/Users/flavio/test.txt'

open(file, 'a').close()

#or

open(file, mode='a').close()

If the file already exists, its content is not modified. To clear its content, use the w flag instead:

open(file, 'w').close()

#or

open(file, mode='w').close()

When you open a file, you must remember to close it after you’ve finished working with it. In this case, we close it immediately, as our goal is to create an empty file.

Remember to close the file, otherwise it will remain open until the end of the program, when it will be automatically closed.

Alternatively, you can use with:

with open(file, mode='a'): pass

This will automatically close the file.

Creating a file can raise an OSError exception, for example if the disk is full, so we use a try block to catch it and gracefully handle the problem by printing an error message:

file = '/Users/flavio/test.txt'

try:
    open(file, 'a').close()
except OSError:
    print('Failed creating the file')
else:
    print('File created')

One more thing! ⚠️ ✋

At the end of January I will organize the Web Development Bootcamp.

It's a 10-weeks long cohort online course where I will guide you to becoming a Web Developer.

It's not "just a course". It's a big event I organize once a year.

We'll start from zero, learn the fundamentals of Web Development, HTML CSS, JavaScript, Tailwind, Git, using the command line, VS Code, GitHub, Node.js, we'll then learn React, JSX, how to use PostgreSQL, Astro, Next.js, Prisma, deploying on Netlify/DigitalOcean/Fly/Vercel and much more! 

At the end of the first 10 weeks you'll know how to create web sites and web applications and I'll unlock you the 2nd phase of the Bootcamp: you will get access to a large number of projects exclusive to the Bootcamp graduates, so you can follow my instructions to build things like private areas with authentication, clones of popular sites like Twitter YouTube Reddit, create e-commerce sites, and much much more.

Because once you got the fundamentals, you only learn by working on real, exciting projects.
