Use a dictionary instead. var=”%(foo)s %(foo)s %(foo)s” % { ‘foo’: ‘look_at_me_three_times’ } Or format with explicit numbering. var=”{0} {0} {0}”.format(‘look_at_meeee’) Well, or format with named parameters. var=”{foo} {foo} {foo}”.format(foo = ‘python you so crazy’)
There’s no way to do this using String interpolation. You can find a good discussion about this on this Apple Dev Forum post. You can use NSNumberFormatter or NSDateFormatter to format the output. Alternatively, to use printf-like syntax, you can still use NSString: var str = NSString(format: “Hello, world %.2f”, 42.12312312313)
I see now that String implements Write, so we can use write!: use std::fmt::Write; pub fn main() { let mut a = “hello “.to_string(); write!(a, “{}”, 5).unwrap(); println!(“{}”, a); assert_eq!(“hello 5”, a); } (Playground) It is impossible for this write! call to return an Err, at least as of Rust 1.47, so the unwrap should … Read more
I had the same problem, I think in Chart.js 2.x.x the approach is slightly different like below. ticks: { callback: function(label, index, labels) { return label/1000+’k’; } } More in details var options = { scales: { yAxes: [ { ticks: { callback: function(label, index, labels) { return label/1000+’k’; } }, scaleLabel: { display: true, … Read more
You might be reading some out of date docs (e.g. for Rust 0.9) As of Rust 1.0, the way to escape { and } is with another { or } write!(f, “{{ hash:{}, subject: {} }}”, self.hash, self.subject) The literal characters { and } may be included in a string by preceding them with the … Read more
Unfortunately, there’s no built-in support for formatting in string templates yet, as a workaround, you can use something like: “pi = ${pi.format(2)}” the .format(n) function you’d need to define yourself as fun Double.format(digits: Int) = “%.${digits}f”.format(this) This will work only in Kotlin/JVM. There’s clearly a piece of functionality here that is missing from Kotlin at … Read more
