无法理解在以下代码段中如何通过列表切片将字符串中的字符分配给列表

Question

I can't understand how string is assigned to the list

def convert(string): 
    list1 = []
    list1[:0] = string 
    return list1 

# Driver code 
str1 = "ABCD"
print(convert(str1))

Answer 1

As it looks its a way of converting a string to a list, you can do it like

list(string)

but this is also quite interesting as , it takes whatever is the input the append it in the start of the list, from python docs list insertion

list1[0:0] inserts the iterable to before the first element of the list, if you slice the list to go up to zero elemen it gives you an empty list
