Creating a nested dictionary...

[GTXY20]

hello all,

I have the following text file:

1,a,good
1,a,bad
1,b,good
1,c,bad

would like to create a dictionary:

d={1:{'v1':(a,b,c), 'v2':(good)}}

have been trying:

for line in lines:
    uh, tf, tp = line.split('%')
    if uh in d:
        f=d[uh]['v1']
        if tf not in f:
            f.append(tf)
        p=d[uh]['v2']
        if tp is not 'bad' and tp not in p:
            p.append(tp)
    else:
        d[uh]={'v1':[], 'v2':[]}

unfortunately I keep getting where 'bad' is being appended to 'v2':

d={'1': {'v1': ['a', 'b', 'c'], 'v2': ['bad', 'good']}}

actually the code reads as follows but I am still having the same problem:

infile = open('input.txt', 'r')
records = infile.read()
infile.close()
lines = records.split()
d={}
for line in lines:
    uh, tf, tp = line.split('%')
    if uh in d:
        f=d[uh]['v1']
        if tf not in f:
            f.append(tf)
        p=d[uh]['v2']
        if tp is not 'bad' and tp not in p:
            p.append(tp)
    else:
        d[uh]={'v1':[tf], 'v2':[tp]}

unfortunately I keep getting where 'bad' is being appended to 'v2':

d={'1': {'v1': ['a', 'b', 'c'], 'v2': ['bad', 'good']}}

I fail to see any logical reason that 'bad' would not be included in V2 since 'c' is in V1.

Oh I understand, thanks.

In order to remove these 'bad' entries I am thinkig of putting the follwing in after the dictionary is created to remove:

for key in d:
	d[key]['v2'].remove('bad')
