2,608 PointsIs there a reason we're using the .format syntax instead of f-strings?
In this video the example is: print("There are {} tickets remaining: ".format(tickets_remaining))
But with an f-string it's shorter and more readable in my opinion": print(f"There are {tickets_remaining} tickets remaining: ")

Treehouse Project ReviewerIn some situation, it's still better to use .format() even in python 3.5+, especially if you need to feed in multiple arguments, practice will show the difference between the two usages.

Treehouse Project ReviewerHi Chris. I didn't dig too deep in my codes but I will if you require, these are what I use most of the time. One of the usages what I found better when we pass in a dictionary, ex.:
dict_ = { 'first_obj': 'value', 'second_obj': 'value}
print("{first_obj} followed by the {second_obj}".format(dict_))
Or another what I found more clean and clear in django or flask, using the form
"Update {}".format(form.cleaned_data['field'])
over
f"Update {form.cleaned_data['field']}"
All above mentioned examples it's just my opinion, probably I should correct or delete the last comment.

Treehouse Project ReviewerHi Derek, the reason it's used
.format()instead off'{}'to be compatible with python 2.x as well not just 3.5 +. Thef'{}'it's in python 3.5+ and it will not work in python 2.7 for example, but.format()it's still implemented in both versions. Check out this link https://realpython.com/python-f-strings/.
