我有一个Python类的作业,我遇到了一个我不理解的错误.在Windows 7上运行Python IDLE v3.2.2.
以下是问题发生的地方:
#local variables
number=0
item=''
cost=''
#prompt user how many entries
number=int(input('\nHow many items to add?: '))
#open file
openfile=('test.txt','w')
#starts for loop to write new lines
for count in range(1,number+1):
print('\nFor item #',count,'.',sep='')
item=input('Name: ')
cost=float(input('Cost: $'))
#write to file
openfile.write(item+'\n')
openfile.write(cost+'\n')
#Display message and closes file
print('Records written to test.txt.',sep='')
openfile.close

这是我得到的错误:
回溯(最近调用最后一次):文件"I:\ Cent 110\test.py",第19行,在openfile.write(item +'\n')中
AttributeError:'tuple'对象没有属性'write'
