Zero-Experience Needed Tutorials
Build and Deploy a Web App in 30 Minutes with Python
For people with zero or little coding experience
Hello hello my friends, I’m so stoked to finally get to write this article today. Today’s article will kinda be like a review/tutorial that aims to let you build and deploy your own web app in 30 minutes using streamlit.
With a simple python script, anyone can quickly build a presentable web app and deploy it really quickly with minimal coding experience needed.
I’d like to clarify that this is not sponsored and no one reached out to me to do any advertisement of streamlit. A friend of mine told me about it and I just tried it out for about 30–60 mins before writing this article.
The Goal
This is what we’re trying to build + deploy today:
The good news?
12 lines of code.
Yes you heard that right — with this nice side bar, button, number input field and file uploader, the whole thing is just 12 lines of code (including import statements).
Let’s jump right into it
The Code (Build):
[Line 6] — Simple title on our main page
[Line 7] — Simple file uploader on our sidebar with optional parameters passed in. I passed in minimum default value of 1 and step 1 (both optional parameters).
[Lines 12–15] — Assuming there’s a file uploaded and if the user inputs a width number (line 7) of more than one, we’ll first use Pillow (PIL)to open the file (line 13), then convert it to the right structure (line 14), then lastly call the resize function of imutils to resize it to the desired width while keeping the aspect ratio (line 15).
