New submission from Gabriele <gabriele.marra...@gmail.com>: hello, I found this strange issue in my program:
I’m reading a file with 5 columns separated by ‘;’ . Columns 3,4 and 5 can have multiple values and in this case, are separated by ‘,’ . Some values in column 3 can be repeated in each line in the same column. Goal: I want create a dictionary for each line using as a key the value in the first column and another key using the values that are in column 3. If the key in column 3 is already in the dictionary, I want add the value in column 4 to the dictionary for the key that is repeated. Example file: col1;col2;col3;col4;col5 id1;i1;val1;Si1;Da1 id2;i2;val2,val1;Si2,Si1;Da2 id3;i3;val3;Si3;Da3 Expected Result: {‘id1’ : [ 'id1','i1',['val1'],['Si1'],['Da1’] ] , ‘id2’ : [‘ id2','i2',['val2','val1'] ,[Si2,Si1] ,['Da2’] ] , ‘val1’ : [ 'id1','i1',['val2','val1'],['Si2','Si1'],['Da1','Da2’] ] , ‘val2’ : [ 'id2','i2',['val2','val1'],[Si2,Si1] ,['Da2’] ] , 'id3’ : [ 'id3','i3','val3',['Si3'],['Da3’] ] , ‘val3’ : [ 'id3','i3','val3',['Si3'],['Da3’] ] } But what I obtaining is {'id2': ['id2', 'i2', ['val2', 'val1'], ['Si2', 'Si1'], ['Da2'], '5'], 'id3': ['id3', 'i3', ['val3'], ['Si3'], ['Da3'], '5’], 'id1': ['id1', 'i1', ['val1'], ['Si1', 'Si2', 'Si1'], ['Da1', 'Da2'], '5'], 'val3': ['id3', 'i3', ['val3'], ['Si3'], ['Da3'], '5'], 'val2': ['id2', 'i2', ['val2', 'val1'], ['Si2', 'Si1'], ['Da2'], '5'], 'val1': ['id1', 'i1', ['val1'], ['Si1', 'Si2', 'Si1'], ['Da1', 'Da2'], '5']} My bug: Key id1 was called just one time in my program, but in my results, I can find that list in position 3 is with 3 value (Si1 , Si2 , Si1) when it supposes to have just Si1. Am I doing something wrong or this is a potential bug? I ran the program using a different machines and different python versions, but results don't change. ---------- files: program.py messages: 357894 nosy: malbianco priority: normal severity: normal status: open title: Value add to the wrong key in a dictionary type: behavior versions: Python 3.6 Added file: https://bugs.python.org/file48759/program.py _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38984> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
