Hướng dẫn how to split list of list in python - cách tách danh sách danh sách trong python

Vì vậy, tôi muốn phân chia một danh sách các danh sách.

Mã là

myList = [['Sam has an apple,5,May 5'],['Amy has a pie,6,Mar 3'],['Yoo has a Football, 5 ,April 3']]

Tôi đã thử sử dụng cái này:

for i in mylist:
  i.split(",")

Nhưng nó giữ cho tôi thông báo lỗi

Tôi muốn có được:

["Amy has a pie" , "6" , "Mar 3"] loại định dạng này
