Easier signup makes more registrations and helps you cover your django web hosting charges . The package is managed at github here, but it does not have a stable release yet.

The printf or sprintf function is used to format strings in PHP and C programming constructs. sprintf in php returns the formatted string whereas printf just prints the output.

$variable = sprintf("%d %s %d = %d",4,"+",5,9);
print $variable;
//OR
printf("%d %s %d = %d",4,"+",5,9);
 
//Both lines are identical.
//Prints 4 + 5 = 9

On python, sprintf is handled using an operator instead of function. The % operator on a string does formatting.

var = '%d %s %d = %d' % (4,'+',5,9)
