question: public static String pythonEscape ( String s ) { StringBuilder sb = new StringBuilder ( ) ; for ( int i = 0 ; i < s . length ( ) ; i ++ ) { char c = s . charAt ( i ) ; switch ( c ) { case '\n' : sb . append ( "\\n" ) ; break ; case '\r' : sb . append ( "\\r" ) ; break ; case '\t' : sb . append ( "\\t" ) ; break ; case '\\' : sb . append ( "\\\\" ) ; break ; case '\"' : sb . append ( "\\\"" ) ; break ; case '\'' : sb . append ( "\\\'" ) ; break ; default : sb . append ( c ) ; } } return sb . toString ( ) ; }
target:  We escape some characters in s to be able to make the string executable from a python string
