我正在制作一個可以解決簡單統計問題的應用程式。我目前正在研究計算眾數、均值和中位數的方法。平均值和中位數在他們的位置上正確顯示，但眾數沒有。它顯示一個“N”，我不知道它為什么這樣做。請告訴我如何解決它，并告訴我它是什么以及它意味著什么，因為我想從中學習。
uj5u.com熱心網友回復：
那是因為什么時候len(mode) == list_data_len是True，get_mode才會被分配"No mode found"。所以text=get_mode[0]將分配"N"給標簽。get_mode = ["No mode found"]應該改用：
def calculate():
...
if len(mode) == list_data_len:
get_mode = ["No mode found"]
else:
get_mode = [str(i) for i in mode]
mode_label.config(text=get_mode[0])
