Fill up a string with leading 0s

There's no zfill() in D, but we can do it easily 🎯

(1) `zfill()`
def main(): s = "7" print(s.zfill(3)) # "007" s = "12345" print(s.zfill(2)) # "12345"	import std.stdio; import std.string; string zfill(const string s, const int width) { return s.rightJustify(width, '0'); } void main() { string s = "7"; writeln(s.zfill(3)); // "007" s = "12345"; writeln(s.zfill(2)); // "12345" }
