问题描述

初学者python 'str' object has no attribute 'vals' 怎么解决啊

代码如下
import sqlite3
def convert(value):

  if value.startswith('~'):
      return value.strip('~')
  if not value:
      value = '0'
      return float(value)

conn=sqlite3.connect('food.db')
curs=conn.cursor()

try:
curs.execute('''
CREATE TABLE food (
id TEXT PRIMARY KEY,
desc TEXT,
water FLOAT,
kcal FLOAT,
protein FLOAT,
fat FLOAT,
ash FLOAT,
carbs FLOAT,
fiber FLOAT,
sugar FLOAT
)
''')
except:
pass

query = 'INSERT INTO food VALUES (?,?,?,?,?,?,?,?,?,?)'

for line in open('ABBREV.txt'):
fields=line.split('^')
vals = [convert(f) for f in fields[:10]]
curs.execute(query. vals)

conn.commit()
conn.close()

错误代码 AttributeError: 'str' object has no attribute 'vals' 怎么办啊

解决方案

curs.execute(query. vals) ？？？

这是要干啥？

query是一个字符串，vals上面算出来的列表

如果是想把vals追加到query后面，

query + ','.join(vals)

解决方案二：

把value与startswith中间的" . "改为 " , "
