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)
with open("batch3.csv", "a") as f:
f.write(newLine)
