Iteration inside a LatexExpr

For presentation reason I have a show like the following one :

show(LatexExpr(r"\text{The variable } x[i] \text{ takes the value :}"), x[i])

How could I have an iteration on on I to display in the text say $x_1$, ...,$x_{10}$ in place of the x[i].

Something like this:

x = [i^2 for i in range(20)]  # for testing purposes
for i in range(1, 11):
    show(LatexExpr(fr"\text{{The variable }} x_{{{i}}} \text{{ takes the value :}}"),
         x[i])

Python formatted strings or f-strings can include things in {}.

Escaping that inclusion mechanism to get actual braces is done using {{}}.

What means the f in front of the r and why the \text need double {{

The r stands for raw string and f for f-string. See here for the later case.
