Berry: question on time formatting with f-strings

[forumlw06]

Hello Berry experts,

i am using berry more and more, and i was wondering if i can use f-strings to format time.
Please see following small example. The first result is what wi would like to achieve with f-strings only (if possible at all).

I know, i could first materialize "tasmota.strftime("%H:%M:%S", 1745191441)" to a variable and then use that again in an f-string, but was wondering if there is a way in doing that without that tweak.

Thanks in advance

var label='Time'
var tstr=string.format("%-9s| %s", label, tasmota.strftime("%H:%M:%S", 1745191441))
print(tstr)

---> Result: Time     | 23:24:01

tstr=f'{label:%-9s}| ')

---> Result: Time     | 

tstr=f'{label:%-9s}| {tasmota.strftime("%H:%M:%S", 1745191441):%s}'
print(tstr)

---> Result: BRY: Exception> 'syntax_error' - input:2: unexpected symbol near ':'

Don't expect "any expression" to get past the lexer within f-strings. While it can handle more than just simple variables, the colon will be problematic as it is also part of the syntax for the f-string.

One additional workaround could be to have the strftime pattern in a variable or function call.
