如何用數組中的字符串替換空值（python）？

Question

我想輸入玩家的姓名到我的陣列中。我將數組設置爲空，現在我將如何將用戶給出的名稱放入數組中？

1.Here是我到目前爲止編碼：

def randName(team_names): 
    team_names = list(team_names) 
    shuffle(team_names) 
    leftover = team_names.pop() if len(team_names) % 2 else None 
    trick = [iter(team_names)] * 2 
    pairs = list(zip(*trick)) 
    return pairs, leftover 

teamNames = [] 
name = "" 

while name != "end": 
    name = raw_input ("Enter the name of an opponent: (end to exit)") 
    teamNames.append(name) 

teamNames.pop() 

chart = np.empty((len(teamNames)/2,2), dtype=np.str) 

print chart 

Answer 1

在numpy的，你可以通過引用到要改變的元素的索引改變一個數組的值，例如：

chart[0,1] = 'Name'
