string — Common string operations
It is exposed as a separate function for cases where you want to pass in a predefined dictionary of arguments, rather than unpacking and repacking the dictionary as individual arguments using the *args and **kwargs syntax. vformat() does the work of breaking up the format string into character data and replacement fields.
Why use string.format instead of f strings?
In the example you provided, there's no reason not to use an f-string. Corey Schafer's videos are good, so I'm going to assume he just didn't cover f-strings yet. But sometimes, str.format can be useful. You can construct string templates and provide the arguments later, while f-strings are instantly evaluated. # Not the best use-case, but I wanted to focus on the idea example = "Hello, {}, how are you?" john = example.format('John') kevin = example.format('Kevin') More on reddit.com

r/learnpython on Reddit: Why use string.format instead of f strings?
March 6, 2021 -
Now AFAIK there are some times when you need to use .format() to do something (off the top of my head, displaying a number to a certain number of digits), but as far as just basic things like displaying an email address, something like:
return "{}.{}@email.com".format(first, last)
why not just do f"{first}.{last}@email.com?
I only ask this because this example is in a Corey Schafer video I'm watching and was wondering if I'm missing something or if this is just one of those bad habits that programmers more knowledgeable than me just might have

f-strings are somewhat new; they were introduced with python 3.6 and it always takes a couple years for a new feature to be widely adopted. Any older videos or tutorials won't use them because they didn't exist then. Other than that the only time I see you may want to use format() instead is when you want to store the template in a different place. TEMPLATE = "{}.{}@email.com" def create_email(first, last): return TEMPLATE.format(first, last) Which happens a decent amount. FWIW f-strings can do everything format() does, including displaying a certain number of digits. >>> import math >>> f"I like {math.pi:.2f}" 'I like 3.14'
