That's because you have the 3 lines below which we hadn't seen yet.

OK, so I now have some code I can actually run. Unfortunately, it
produces an error:
Traceback (most recent call last):
File "ricardo.py", line 23, in <module>
aging_dict['total'], aging_dict[columns] = total, aging_values
NameError: name 'total' is not defined
So I'll make a reasonable guess that you meant total_values there. I
still can't understand how you're testing this code, when there are
trivial bugs in it.
Next, I get:
Traceback (most recent call last):
File "ricardo.py", line 32, in <module>
highway_dict['lanes'], highway_dict['state'],
highway_dict['limit(mph)'] = lanes, state, limit_values
NameError: name 'lanes' is not defined
and then:
Traceback (most recent call last):
File "ricardo.py", line 32, in <module>
highway_dict['lanes'], highway_dict['state'],
highway_dict['limit(mph)'] = lanes_values, state, limit_values
NameError: name 'state' is not defined
Each of those not-defined errors was pointed out by me earlier in the
thread.
I don't see any output logic, so I guess it's up to us to guess what the
meanings and scope of the various lists and dicts are. I figure the
queue_row is your final collection that you hope to get results from.
It's a list containing many references to a single queue_counters
object. So naturally, they all look the same.
If you want them to be different, you have to create a new one each
time. Move the line:
queue_counters={}
inside the loop, right after the line:
for content in file_content:
There are a bunch of other things wrong, like not lining up the columns
when you're substringing content, but this may be your major stumbling
block. Note: you may have to also move the highway_dict and
aging_dict; I haven't figured out what they're for, yet.
Following is the code I've been using to try to figure out what you were
intending:
file_content = [
"aging 0 100",
"aging 2 115",
"aging 3 1",
"highway 4 disable 25",
"highway 2 disable 245",
"highway 0 enable 125",
]
highway_dict = {}
aging_dict = {}
#queue_counters={}
queue_row = []
for content in file_content:
queue_counters={}
if 'aging' in content:
# aging 0 100
columns = ', '.join(map(str,
content[:1])).replace('-','_').lower()
print "columns:", columns
total_values =''.join(map(str, content[1:2]))
aging_values = '\t'.join(map(str, content[2:]))
aging_dict['total'], aging_dict[columns] =
total_values, aging_values
queue_counters[columns] = aging_dict
if 'highway' in content:
#highway | 4 | disable | 25
columns = ''.join(map(str,
content[:1])).replace('-','_').lower()
lanes_values =''.join(map(str, content[1:2]))
state_values = ''.join(map(str, content[2:3])).strip('')
limit_values = ''.join(map(str, content[3:4])).strip('')
highway_dict['lanes'], highway_dict['state'],
highway_dict['limit(mph)'] = lanes_values, state_values, limit_values
queue_counters[columns] = highway_dict
queue_row.append(queue_counters)
print
print "h dict:", highway_dict
print
print "aging dict:", aging_dict
print
print "q counters:", queue_counters
for key, item in queue_counters.iteritems():
print key, item
print
print "q row:", queue_row
for item in queue_row:
print item
