In this example, the format() function formats the sales amount with a comma as a thousand separator and two decimal places. Then, you add a dollar sign using an f-string. This helps present financial data clearly and professionally.
Is .format() still efficient and used?
It has the advantage of being able to put variables after instead of having to do it at the time that the string is created. As an example, if I want to print a format for a list (to make it look like a table), I can re-use a .format() string like so: table_fmt = "name: {:8} age: {:8} weight: {:3}" items_1 = ("John", 35, 180) items_2 = ("Susan", 35, 130) print(table_fmt.format(*items_1)) print(table_fmt.format(*items_2)) Or if I want to print in a different order, I can also do something like: order = ("Pizza", 25.00, "Visa", "ACCEPTED") fmt = "status: {3}, item: {0}, cost: {1}, payment method: {2}" print(fmt.format(*order)) You can also put in a function result in a .format() string without it breaking the readability, while the same isn't true for f-strings: value = 20.0 def price_after_taxes(cost): return cost * 1.05 print("After taxes, you have to pay {} for your pizza".format(price_after_taxes(cost))) So it is useful in some cases, although f strings usually are a lot faster and nicer to read. It's a tradeoff between readability and flexibility. More on reddit.com

Yea I think that's just not worth it heh. I am looking more for a syntax that is permited there, for example, to format a datetime you can do {:%Y} and it works. 2013-11-05T18:46:44.757Z+00:00 ... I'm sorry that's all I got :) I don't think Python goes so far. More on stackoverflow.com

See the Format examples section for some examples. “Format specifications” are used within replacement fields contained within a format string to define how individual values are presented (see Format string syntax, f-strings, and t-strings). They can also be passed directly to the built-in format() function.

May 18, 2022 - The values in the str.format() method are primarily tuple (tuples are a sequence of immutable Python objects) data types. Every value in the tuple is referred to by its indexes starting from 0. These index numbers are then passed into the placeholders, and then they get substituted with the values. Positional arguments are arguments that refer to the values at a specific index number while calling a function. They can be used to get a particular value in place of the placeholder while formatting strings. ... In the above example, we are using index numbers in placeholders to refer to the values inside the str.format() method and insert them in the string.

Python's string Template class provides another way to format strings using a simpler syntax. While less powerful, it can be useful for straightforward substitutions. An example might be handling user-generated format strings (to avoid security issues).

r/learnpython on Reddit: Is .format() still efficient and used?
March 3, 2022 -
I have been learning Python for a few days now. I learnt about f-strings, they seem a lot more easy to me than the .format() method. Because you can immediately call in the variables inside the strings. And I looked up a few other resources while learning, some are still using .format() method. Does it have any advantages over f-strings or it's just a matter of choice?

The precision is a decimal number indicating how many digits should be displayed after the decimal point for a floating point value formatted with ‘f’ and ‘F’, or before and after the decimal point for a floating point value formatted with ‘g’ or ‘G’. For non-number types the field indicates the maximum field size - in other words, how many characters will be used from the field content.

F-String was introduced in Python 3.6, and is now the preferred way of formatting strings. To specify a string as an f-string, simply put an f in front of the string literal, and add curly brackets {} as placeholders for variables and other operations. ... A placeholder can contain variables, operations, functions, and modifiers to format the value.

Not sure if you can modify the object, but you could modify or wrap the object to make the functions properties. Then they would look like attributes, and you could do it as
class WrapperClass(originalRequest):
@property
def full_name(self):
return super(WrapperClass, self).full_name()
"{0.full_name} {0.full_last_name} and my nick name is {0.full_nick_name}".format(user)
which IS legal.

Python 3.6 adds literal string interpolation, which is written with an f prefix. See PEP 0498 -- Literal String Interpolation.
This allows one to write
>>> x = 'hello'
>>> s = f'{x}'
>>> print(s)
hello
It should be noted that these are not actual strings, but represent code that evaluates to a string each time. In the above example, s will be of type str, with value 'hello'. You can't pass an f-string around, since it will be evaluated to the result str before being used (unlike str.format, but like every other string literal modifier, such as r'hello', b'hello', '''hello'''). (PEP 501 -- General purpose string interpolation (currently deferred) suggests a string literal that will evaluate to an object which can take substitutions later.)

Within a format string, each positional argument is identified with a number, starting from zero, so in the above example, ‘a’ is argument 0 and ‘b’ is argument 1. Each keyword argument is identified by its keyword name, so in the above example, ‘c’ is used to refer to the third argument. There is also a global built-in function, ‘format’ which formats a single value:
