Python 多线程时，报错'应用程序调用一个已为另一线程整理的接口'，折腾我一晚上了

主要代码是这样的，采用多线程调用 process，process 再去调用其它函数

from multiprocessing.dummy import Pool as ThreadPool import pythoncom global wb def process(r): sht = wb.sheets["开户案例"] sht.range((r,1)).value = '正在发送账户申请...' result = accinfo(wb, r) #所在行，根据这个所在行，去进行后续操作 sht.range((r,1)).value = result pool = ThreadPool(5) list_args=[] for r in rows: list_args.append(r.row) r1=pool.map(process, list_args) pool.close() pool.join() 

提示的报错信息比较多
