Sprint & Sprintf
Sprint 使用其操作数的默认格式格式化并返回结果字符串。
当两者都不是字符串时，在操作数之间添加空格。

// Sprint formats using the default formats for its operands and returns the resulting string.
// Spaces are added between operands when neither is a string.
func Sprint(a ...any) string {
	p := newPrinter()
	p.doPrint(a)
	s := string(p.buf)
	p.free()
	return s
}

Sprintf 根据格式说明符格式化并返回结果字符串。

// Sprintf formats according to a format specifier and returns the resulting string.
func Sprintf(format string, a ...any) string {
	p := newPrinter()
	p.doPrintf(format, a)
	s := string(p.buf)
	p.free()
	return s
}
