String interpolation in python.
The suggestion works, but the f-string is redundant and the syntax verbose. One can just use the similar answer by @ev-kounis, without f-string. It seems f-strings do not improve the printing of lists. –
The str.format () Method. You can use str.format () to interpolate values into your strings. This method operates on a string object where you insert replacement fields as needed.

The answer is 42. As with f-strings, glue returns a string. It doesn’t print the string, though the string is displayed because we’re working from the REPL, the R REPL in this case. Python's f-strings and R's glue package both let you interpolate expressions in strings, using similar syntax.Formatting Option 3 — String Interpolation (Python 3.6+) In Python 3.6, we encounter yet another way to format strings, called Formatted String Literals (Recall that a string literal is any string with "quotes" around it).

Proposal. This PEP proposes the introduction of a new string prefix that declares the string to be an interpolation template rather than an ordinary string: template = i"Substitute {names} and {expressions()} at runtime". This would be effectively interpreted as:

Feb 28, 2022 · Here, we’ve constructed a new string with `%s`python replaced by `name`python and %d replaced by age. In addition to knowing the format specifiers, we’ll want to learn the syntax. In particular, our template string is following by the modulo operator. Of course, in this context, we can call it the string formatting or interpolation operator. Here, the first f-string encounters an expression and evaluates it, and the inner f-string, encounters a string, resulting in the call to LOAD_FAST instead of evaluating the contents of the string as Python code. Also it is important to note in this second example the missing LOAD_FAST calls to both a and b, which are present in the first …String interpolation is a method in Python that allows you to insert variables directly into strings, making your code more readable and efficient.
