如何仅将某些参数传递给函数？

Question

我在Python中有两个数据框。我无法在一个函数中传递所需的参数。我能够在单独的函数中传递它们。假设我需要对两个数据框进行切片，并将相同的东西插入相同的索引。

我尝试将两个数据帧连接起来，以查看哪个插槽为空。

我尝试过的是

def inst(data,people):
    A,B = *data
    length = len(people)
    for item i in range(7-length):
        if not(any(data["Name","Team"][i:i+length])) and len(data)>1:
            DATAFRAMEA["Name","Team"][i:i+length] = people
            DATAFRAMEB["Name","Team"][i:i+length] = people
            return
        elif not(any(data["Name","Team"][i:i+length])) and data == DATAFRAMEA:
            DATAFRAMEA["Name","Team"][i:i+length] = people
            return
        elif not(any(data["Name","Team"][i:i+length])) and data == DATAFRAMEB:
            DATAFRAMEB["Name","Team"][i:i+length] = people
            return




people = [["Lisa","Alex"],["A","D"]]
data = DATAFRAMEA+DATAFRAMEB
inst(data,people)
people = [["James"],["B"]]
inst(DATAFRAMEA,people)

数据帧A

       Name   Team  
0      John     A    
1      
2   Michael     B     
3    Joanna     C     
4     Sinus     B     
5
6
7

数据帧B

       Name   Team  
0      John     A    
1      Jane     D
2   Natasha     B     
3    Joanna     C     
4         
5
6
7     Joshua     B
