[已解决]练习函数的时候出现错误，求助是什么问题

>>> def models(uncompleted,completed):
        while unp:
                currents=uncompleted.pop()
                completed.apppend(current)
                for current in currents:
                        print("We are printing"+current)
                for complete in completed:
                        print("they are completed"+complete)

                       
>>> uncompleted=['a','b']
>>> completed=[]
>>> models(unp,completed)



Traceback (most recent call last):
  File "<pyshell#44>", line 1, in <module>
    models(unp,completed)
  File "<pyshell#40>", line 4, in models
    completed.apppend(current)
AttributeError: 'list' object has no attribute 'apppend'

就想试下向函数传递列表，出现这样的问题，请问怎么解决？

是append，不是apppend

可以了。



>>> def models(uncompleted,completed):
        while uncompleted:
                currents=uncompleted.pop()
                completed.append(currents)
                for current in currents:
                        print("We are printing"+current)
                for complete in completed:
                        print("they are completed"+complete)

                        
>>> uncompleted=['a','b']
>>> completed=[]
>>> models(uncompleted,completed)
We are printingb
they are completedb
We are printinga
they are completedb
they are completeda
