Dictionaries
Hi,
This might sound weird, but is there a limit how many dictionaries a
can create/use in a single script?
My reason for asking is I split a 2-column-csv (phone#, ref#) file into
a dict and am trying to put duplicated phone numbers with different ref
numbers into new dictionaries. The script deducts the duplicated 46
numbers but it only creates batch1.csv. Since I obviously can't see the
wood for the trees here, can someone pls punch me into the right
direction
...(No has_key is fine, its python 2.7)
f = open("file.csv", 'r')
myDict = {}
Batch1 = {}
Batch2 = {}
Batch3 = {}
for line in f:
if line.startswith('Number' ):
print "First line ignored..."
else:
k, v = line.split(',')
myDict[k] = v
f.close()
for k, v in myDict.items():
if Batch1.has_key(k):
if k in Batch2.has_key(k):
Batch3[k] = v
else:
Batch2[k] = v
else:
Batch1[k] = v
for k, v in Batch1.items():
newLine = "%s,%s" % (k, v)
with open("batch1.csv", "a") as f:
f.write(newLine)
for k, v in Batch2.items():
newLine = "%s,%s" % (k, v)
with open("batch2.csv", "a") as f:
f.write(newLine)
for k, v in Batch3.items():
newLine = "%s,%s" % (k, v)

At a quick glance, I have a couple of suggestions.
command = ['echo', '-n', channel, '|', 'sudo', 'tee', config_file]
sudo doesn't work like this. It doesn't read from standard input. You
need to supply the command as an argument to sudo. Get the sudo
syntax
correct by learning to use it in a shell (eg terminal running bash )
before trying to use it from python code.
Also, I think that passing the pipe character '|' as an argument to
Popen is not the correct way to use pipes.
So, if you figure out how to use sudo without '|' you will solve both
these issues.
Or try to change the permissions
os.system("chmod 666 config_file)
do what you want with the file and set the permissions back to their
original state.
