import csv
# initialize with empty ints and dicts
name,cities,countries,states=[],[],[],[]
with open('ind.csv','rb') as csvfile:
reader = csv.reader(csvfile, delimiter=',')
reader.next() #skip header
for row in reader:
name.append(row[0])
cities.append(row[2])
states.append(row[3])
countries.append(row[4])
cl = list(set(countries))
sl = list(set(states))
citl = list(set(cities))
inf1 = list(set(name))
with open('countries.csv','w') as cfile:
writer = csv.writer(cfile, delimiter=',')
writer.writerow(['country_id','name'])
for i,x in enumerate(cl):
writer.writerow([i,x])
with open('state.csv','w') as cfile:
writer = csv.writer(cfile, delimiter=',')
writer.writerow(['state_id','country_id','state'])
for i,x in enumerate(sl):
writer.writerow([i,x,cl.index(countries[states.index(x)])])
with open('cities.csv','w') as cfile:
writer = csv.writer(cfile,delimiter=',')
writer.writerow(['city_id','city','st_id','country_id'])
for i,x in enumerate(citl):
writer.writerow([i,x,sl.index(states[cities.index(x)]),
cl.index(countries[cities.index(x)])
])
with open('inf123.csv','w') as cfile:
writer = csv.writer(cfile,delimiter=',')
writer.writerow(['Name_id', 'Name','city_id','st_id','country_id'])
for i,x in enumerate(inf1):
writer.writerow([i,x,
citl.index(cities[name.index(x)]),
sl.index(states[name.index(x)]),
cl.index(countries[name.index(x)])
])
