插入數據3.4

Question

我有一個Postgres的表結構如下

CREATE TABLE edmonton.permit 
          (permit_date text, 
          permit_number text, 
          year numeric, 
          month_number integer, 
          report_permit_date text, 
          job_category text, 
          address text, 
          legal_description text, 
          neighbourhood text, 
          neighbourhood_number text, 
          job_description text, 
          building_type text, 
          work_type text, 
          floor_area numeric, 
          construction_value integer, 
          zoning text, 
          units_added numeric, 
          latitude double precision, 
          longitude double precision, 
          location text, 
          count integer 

我想讀一個相對路徑和導入數據的csv文件到Postgres的表像之下

   with open(file) as f: 
       reader = csv.reader(f, delimiter=',') 
       next(reader, None) 
       for row in reader: 
        cur.execute("INSERT INTO edmonton.{}(permit_date, permit_number, year, month_number, report_permit_date, job_category, address, legal_description, neighbourhood, neighbourhood_number, job_description, building_type, work_type, floor_area, construction_value, zoning, units_added, latitude, longitude, location, count) VALUES (%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s)".format(permit),row) 
        con.commit() 

我提示以下錯誤：

Invalid literals for numeric datatype. 

什麼地方持有人應用於數字，整數，雙精度使用python3.4？

這可能有助於縮小範圍。將嘗試格式化每個字段，並給出導致問題的錯誤。

with open(file) as f: 
reader = csv.reader(f, delimiter=',') 
next(reader, None) 
for row in reader: 
    for item in row: 
     print cursor.mogrify("%s", (item,))
