我的 python csv 解析器有问题,我不知道错误发生在哪里:
这是我的Python:
# -*-coding:Utf-8 -*
import sqlite3;
from datetime import datetime, date;
conn = sqlite3.connect('info_max.sqlite3')
conn.text_factory = str
c = conn.cursor()
c.execute('drop table if exists info_max')
c.execute('create table info_max(id_huiles text, name_fr text, name_ln text, img text, mode_obt text, bien_vertus text, bio text)')
def mysplit(string):
quote = False
retval = []
current = ""
for char in string:
if char == '"':
quote = not quote
elif char == ',' and not quote:
retval.append(current)
current = ""
else:
current += char
retval.append(current)
return retval
# Lit de ligne en ligne, en sautant la première ligne
rawdata = open("info_max_try.csv", "r").read()
data = rawdata.split("\n", 1)[1:]
data = re.split('"END"', rawdata)
print(data)
for entry in data:
# Parse les valeurs
vals = mysplit(entry.strip())
# Convertit les strings format heure au format standard sqlite3
# Insert la ligne
vals[0] = int(vals[0])
print "Inserting %s..." %(vals[0])
print "The enrty is : %s" %entry
sql = "insert into info_max values(?, ?, ?, ?, ?, ?, ?)"
c.execute(sql, vals)
# Done !
conn.commit()
我的.csv
看起来像这样:
"id_huiles","name_fr", "name_ln", "img", "mode_obt", "bien_vertus","bio"
"77", "Basilic", "Basilium", "Basilic.png", "some_text", "some_text", "0"
...
输入 3 次后我收到此错误:
File "parseAromaHuile.py", line 39, in <module>
c.execute(sql, vals)
sqlite3.ProgrammingError: Incorrect number of bindings supplied. The current statement uses 7, and there are 6 supplied.
编辑
我的行中有 \n
..我修改了我的代码,但我不希望我的解析器读取我的第一行
有问题的行如下所示:
"6","Bergamote", "Citrus bergamis L.", "bergamote.png", "some_text", "some_text\n other_text\n more_text","0"
感谢您的帮助!
最佳答案
我认为问题出在你的 mysplit
函数中,在某个地方(这个 if/elif 似乎很可疑)它返回一个包含 6 个元素而不是 7 个元素的列表。
试试这个:
import sqlite3;
import csv
from datetime import datetime, date;
conn = sqlite3.connect('info_max.sqlite3')
conn.text_factory = str
c = conn.cursor()
c.execute('drop table if exists info_max')
c.execute('create table info_max(id_huiles text, name_fr text, name_ln text, img text, mode_obt text, bien_vertus text, bio text)')
with open('info_max.csv','rb') as source:
#I use csv reader instead of writing my own
data = csv.reader(source, delimiter=';')
header = data.next()
for vals in data:
for val in vals:
#I use replace function to get rid of qoutes
val.replace('"', '')
#adds the string "missing data" if some column is missing in your source
if len(vals) < 6:
vals += ['missing data' for i in range(0,6-len(vals))]
vals[0] = int(vals[0])
print "Inserting %s..." %(vals[0])
print "The enrty is : %s" %vals
sql = "insert into info_max values(?, ?, ?, ?, ?, ?, ?)"
c.execute(sql, vals)
conn.commit()
