Python's F-String for String Interpolation and Formatting – Real Python
November 30, 2024 - Python will replace those expressions with their resulting values. So, this behavior turns f-strings into a string interpolation tool. In the following sections, you’ll learn about f-strings and use them to interpolate values, objects, and expressions in your string literals. ... F-strings make the string interpolation process intuitive, quick, and concise. The syntax is similar to what you used with .format(), but it’s less verbose.

r/learnpython on Reddit: Purpose of the F-string
February 23, 2023 -
Can someone explain in just simple terms what the purpose of the f-string does. I know how to write it in and stuff just what does it help do that makes it a better alternative let’s say in this scenario:
print(‘Movie ticket price:’, movie_ticket_price) or print(f’Movie ticket price: {movie_ticket_price}’)

It's a better alternative if you need to inject several variables into the string, like if you wanted to write: print(f’Movie ticket price: {movie_ticket_price}\n Movie time: {movie_time}\n Movie length: {movie_length}. Etc.’) Is imho easier to read and modify than this, where you need to open and close quotes at every string segment: print(`Movie ticket price:` + movie_ticket_price + `\nMovie time:` + movie_time + `\nMovie length:` + movie_length + `. Etc.’) And those 2 are still, imo, easier to read than % and .format() xD

print(‘Movie ticket price:’, movie_ticket_price) This only works if you're printing. What if you want to format a string but not print it? Also, f-strings, as their name implies, have many formatting options, like aligning text and limiting how many decimals are printed.

In Python, we can create strings that contain dynamic values with the f-string syntax. num_bananas = 10 bananas = f"You have {num_bananas} bananas" print(bananas) # You have 10 bananas · Add an f to the start of quotes to create an f-string: f"this is easy!"

This is called f-strings and are quite straightforward : when using an "f" in front of a string, all the variables inside curly brackets are read and replaced by their value. For example :
age = 18
message = f"You are {age} years old"
print(message)
Will return "You are 18 years old"
This is similar to str.format (https://docs.python.org/3/library/stdtypes.html#str.format) but in a more concise way.

String starting with f are formatted string literals.
Suppose you have a variable:
pi = 3.14
To concatenate it to a string you'd do:
s = "pi = " + str(pi)
Formatted strings come in handy here. Using them you can use this do the same:
s = f"pi = {pi}"
{pi} is simply replaced by the value in the pi

F strings are just a nice way to insert variables into a template string. Yes, there are other ways - but f strings are usually the best. What way would you use instead?

In the above example, using the f-strings approach, we fill each placeholder (i.e., each pair of braces) with a variable name whose value we want to display. Note that to use an f-string, we must type the character “f” before the string content. We can then enter expressions within the string between curly braces ({}). Whenever the python interpreter encounters curly braces inside an f-string, it will evaluate the expression and substitute the resulting value into the string.
