Probably this step,

1, read the A2. TXT
Build a dictionary students={' 41900001 ': [' Angela],' 41900002 ': [' Chen']}

2, read B2. TXT

List your homework to the students,

Students={' 41900001 ': [' Angela' [' 3 ', '4', '1', '2', '5']], '41900002' : [' Chen ', '3', '2', '5', '4', '1', '6']}

3, processing jobs list, you can use the set to heavy, to list sorting,

4, the output
