mysql - python:type error while connection -


this question exact duplicate of:

enter image description here got error on code 

    if rows[0] in line: typeerror: 'in <string>' requires string left operand, not tuple

my code:

import mysqldb  db = mysqldb.connect(host="localhost", # host, localhost                          user="root", # username                           passwd="mysql", # password                           db="sakila") # name of data base cursor = db.cursor()      # execute sql select statement cursor.execute("select student myclass") rows=cursor.fetchall()    open('qwer.txt','r') file:     line in file:         row in rows:             if rows[0] in line:                stmt="select english marks student = :student"                cursor.execute(stmt,dict(student=row[0]))                print "english marks:",cursor.fetchall()[0][0]

please help,since doesnot provide me output no errors

you using rows[0] meant use row[0] instead:

for row in rows:     if row[0] in line:

rows list of tuples, rows[0] first such tuple. row[0] first column in current row (e.g. student column select).

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...
