我在ubuntu中使用了相同的代碼,它工作正常,但是當我試圖在windows中運行它時,它給了我一個「()」輸出。可能是什麼原因。我是這個新的領域,我需要assistance.`python中沒有插入數據的數據
import csv
import string
import MySQLdb
with open('cool1.txt','r') as csvfile:
scoreFileReader=csv.reader(csvfile)
scoreList=[]
for row in scoreFileReader:
if len(row) !=0:
scoreList=scoreList + [row]
csvfile.close()
print(scoreList)
temp=str(scoreList).translate(string.maketrans('', ''), '[]\'')
#print(temp)
db = MySQLdb.connect("localhost","root","","test123")
#setup cursor
cursor = db.cursor()
#create anooog1 table
cursor.execute("DROP TABLE IF EXISTS db1234")
sql = """CREATE TABLE db1234 (
uid VARCHAR(100) NOT NULL,
price INT(100) NOT NULL)"""
cursor.execute(sql)
try:
cursor.execute("""INSERT INTO db1234 VALUES (%s,%s)""",(scoreList))
db.commit()
except:
db.rollback()
#how table
cursor.execute("""SELECT * FROM db1234;""")
print cursor.fetchall()
db.close()
和文本文件中的數據看起來好像是這些:
E0 C1 7F 7A
0
除了錯誤移除後,來到像這樣的
[['E0 C1 7F 7A'], ['0']]
Traceback (most recent call last):

除外條款有人來

不要使用空'除外:'條款。您可能會收到阻止數據插入的錯誤。 – bernie
輸出是這樣的 – Fiore
您有兩個佔位符和一個項目插入每次迭代。這是行不通的。 – bernie
