CSV TO SHAPEFILE - Using pyshp

Question

I need a help.

I got some CSV files with geographic information and I need to convert it to SHP... I'm trying the following code, but it's not working..

This is my first time working with python.. I'd really appreciate if you could help me.

import shapefile as shp
import csv

out_file = 'test.shp'

#Set up blank lists for data
lat,lon=[],[]

#read data from csv file and store in lists
with open('input.csv', 'rt') as csvfile:
    r = csv.reader(csvfile, delimiter=';')
    for i,row in enumerate(r):
        if i > 0: #skip header
            lat.append((row[0]))
            lon.append((row[1]))

#Set up shapefile writer and create empty fields
w = shp.Writer(shp.POINT)
w.autoBalance = 1 #ensures gemoetry and attributes match
w.field('lat','F',10,8)
w.field('lon','F',10,8)
w.field('Date','D')
w.field('Target','C',50)
w.field('ID','N')

#loop through the data and write the shapefile
for j,k in enumerate(x):
    w.point(k,y[j]) #write the geometry
    w.record(k,y[j],date[j], target[j], id_no[j]) #write the attributes

#Save shapefile
w.save(out_file)

This is what the spyder returns to me:

I was able to accomplish this using arcpy modules MakeXYEventLayer_management followed by CopyFeatures_management. Example below

import arcpy 
arcpy.env.workspace = r"C:/home"
csvFile = r"C:/home/some.csv"
in_x_field = "long"
in_y_field = "lat"
out_layer = "csvLayer"
spatial_reference = 4326

csvLayer=arcpy.MakeXYEventLayer_management(csvFile,in_x_field,in_y_field,out_layer,spatial_reference)
arcpy.CopyFeatures_management(csvLayer,"shapename.shp")
