Python Engineer is now on Substack

Welcome to my first email on Substack

Hey there 👋

This is Patrick writing to you from a new platform. You might be surprised to see a new email address since you probably subscribed on the Python Engineer website or on Revue. I moved my newsletter to Substack, so don’t worry, it’s still me.

❓What can you expect?

This will be a newsletter featuring tutorials, news, trends, and educational nuggets related to Python & AI. For the time being, I want to send out new issues every month.

⚡️Thanks to our Sponsors who keep this Newsletter free

This first issue is brought to you by Underfitted, another AI newsletter from my friend Santiago. Every Friday, you'll get a short, exciting story about Artificial Intelligence that will inspire and make you smarter. And all of this in fewer than 500 words! Click here to subscribe.

💡Python Tip

How to pad zeros to a String: zfill, rjust, or String formatting:

"42".zfill(5)         # '00042'
"-42".zfill(5)        #'-0042'

"42".rjust(5)         # '   42'
"42".rjust(5, "0")    # '00042'
"-42".rjust(5, "0")   # '00-42'

n = 42
f'{n:05d}'            # '00042'
n = -42
f'{n:05d}'            #'-0042'

I hope you enjoyed the read!
