Is_sum_odd that takes a non-negative integer number as parameter and returns true if the sum of individual digits is odd, false otherwise.

Make sure that you understand how addDigits( number, base ) works!

```
#!/usr/bin/python

import sys

def addDigits( number, base ):
    if( number ):
        return( addDigits( number // base, base ) + ( number % base ) )
    else:
        return( 0 )

def wrapper( number, base=10 ):
    if( ( addDigits( number, base ) ) % 2 ):
        return True
    else:
        return False

if( __name__ == "__main__" ):
    if( len( sys.argv ) != 2 ):
        sys.stderr.write( "usage: " + sys.argv[ 0 ] + " <integer>\n" )
        exit( 127 )

    print wrapper( int( sys.argv[ 1 ] ) )
```
