I need to write a code to populate 450 schemas having same table names and also specify the columns needed to be inserted. for that i am trying to make the Schema Name a variable and put the whole statement in a loop to change the name of the Schema. its not working can any one guide me in this..Thae sample of my insert statement is
INSERT INTO A01.tablename
In this the "A" is constant and 01 is being changed to 02...450..

Not sure to completely understand your need, but assuming that column names and values to be inserted are the same for all schemas, here a short example :
SQL> desc a001.test
Name                                      Null?    Type
A                                                  NUMBER
B                                                  VARCHAR2(10)
SQL> desc a002.test
Name                                      Null?    Type
A                                                  NUMBER
B                                                  VARCHAR2(10)
SQL> desc a003.test
Name                                      Null?    Type
A                                                  NUMBER
B                                                  VARCHAR2(10)
SQL> declare
  2     i       number;
  3     str     varchar2(100);
  4  begin
  5     for i in 1..3 loop
  6             str := 'insert into a'||lpad(i,3,'0')||'.test(a,b) values(1,'||chr(39)||'ABC'||chr(39)||')';
  7             execute immediate (str);
  8     end loop;
  9     commit;
10* end;

SQL> select * from a001.test;
         A B
         1 ABC
SQL> select * from a002.test;
         A B
         1 ABC
SQL> select * from a003.test;
         A B
         1 ABC
