How to split a list of lists

So I want to split a list of lists.

the code is 

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

I tried use this:

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

But it keeps give me error message

I want to get:

Another way would be:

list(map(lambda x: x[0].split(","), myList))

Here's how you do it. I used an inline for loop to iterate through each item and split them by comma.

myList = [item[0].split(",") for item in myList]
print(myList)

OR You can enumerate to iterate through the list normally, renaming items as you go:

for index, item in enumerate(myList):
    myList[index] = myList[index][0].split(",")
print(myList)

OR You can create a new list as you iterate through with the improved value:

newList = []
for item in myList:
    newList.append(item[0].split(","))
print(newList)

Split each string in sublist :)

new = []
for l in myList:
    new.append([x.split(',') for x in l])

print new

It's because it's a list of lists. Your code is trying to split the sub-list, not a string. Simply:

for i in mylist:
    i[0].split(",")
