How do I concat strings?

I want to have a timer, and a label on screen 00 01 02 ....
I want to create the string from seconds, so that if it is less than 10 0+seconds

so in a function:
varaible tmp;
if (sec<10) variable ="0" + string of secs ====> concat string
else variable = string of secs

How in ui flow

@alon24 Sorry what is concat strings?

if you are unsure of english words try posting in your language.

[alon24]

"hello" + "world" => "hello world"

"0" + "1" => "01"

surely if and else are showing the same thing?
I'm feeling confused but its something like this.
NOT complete!

I do not think you understand, I want to create a new string to show.
Say I have "hello" and "world" I want to. Create a new string with "hello world" in it.

In js:
Let a= "hello" + "world"

Now a== "hello world"

Hope this is now more understandable, it should be in the text section, something like join action for text

You are correct, I didn't understand.
Hmn, nope I can't find away to do it in UIFlow however there should be away in micropython which is the underlying programming language.

Sorry, I can't help you anymore here.

Doesn't this work?

In micropython it would be the same as python : stringA + stringB

[alon24]

So this worked, because I needed numbers

Would you mind if I added this to my book?

@ajb2k3 Actually, “concat” is a widely recognized and valid term in programming that refers to combining two or more strings. There’s no need to be condescending to a fellow programmer by telling them to “use his language.” He's used English in understandable manner.
