At 4:29:00, for the `prettier_budget` function, there's a much easier way to implement this.
Which is just by using the format string with a colon and comma like "{ :, }" (don't use any space-character in the real code).
E.g.
budget = 1_000_000 # underscore is just a way to make it easier to see
number_with_commas = f'{budget:, }'
number_with_commas

OUTPUT:
'1, 000, 000'

The length of this video is more than 6 hours, instead of discouraging me from watching, it reassures me about the amount of knowledge required in any serious subject, and the dedication of the educator. Thank you very much

Hi everyone
I have an error, which is at 1:36:30, and the error is as follows

>>> from market import db
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'market'

[jonathankristanto]

This course is totally amazing! I've learnt so much and Jim you're such a great educator. Finished this in 5 days and now I'm gonna try to create my own project with Flask Web Framework. Great Job Jim!

[divyanshubhargava]

for those who are getting error in db.create_all() command :
solution : first uninstall current version of flask-sqlalchemy using command "pip uninstall flask-sqlalchemy" and then install flask-sqlalchemy version 2.5.1 by command "pip install flask-sqlalchemy==2.5.1"

I find myself referring my friend to this channel..and for the first time am understanding flask very well...big up

[fernandodaquinta]

This is by far and away the best Flask starter course I have found on YouTube (or any other platform). The realistic example that "Jim" works through provides all the tools and context you need to get started. Highly recommended!

At 1:35:16, for people struggling with comment "RuntimeError: Working outside of application context." and "To solve this, set up an application context with app.app_context()"
With Flask 3.0.2, db.add() and db.commit() as well as as Item.query.all() methods don't work anymore in this way.
Here is the correct code regarding this Flask version:

from market import db, app # don't forget to import app !!!
with app.app_context():
db.create_all()

Then you create your object
from market import Item
item1 = Item(name="Iphone 10", price=500, barcode='123456789123', description="scrappy phone")

The same happened with db.add() and db.commit() :
with app.app_context():
db.session.add(item1)
db.session.commit()


finally, to print items :
with app.app_context():
Item.query.all()

Hope it helps you. I've struggled a lot with this !!

[andercarrasco]

The best course about Flask I've seen in all the internet. Thank you so much for this tutorial.

[KacperMigdal]

Thank you for this amazing course! I really like your style of lessons because you are not ashamed of errors and you explain everything thoroughly! You really made me understand this, thanks a lot!!

[NickBotman]

Thanks a lot for your sharing. I don't know why my database file was created in the "instance" directory but the root directory. Please help!

[joeleone]

If you're having some issues piecing together how Flask works with Python and HTML or how to get your data from Python to your websites, this video does a great job of explaining this in detail! Very helpful!
