string are splitted in 'list()' and not in '[]' why? in python : <br>
I have been working in a project then I accidently 
discovered when I pass 
string,they are splitted in 'list()' but when I pass
same string to '[ ]' there is not splitting into single letters of  string can anyone tell
what happend here..<br>

    >>> y = list("hello")
    >>> y
    ['h', 'e', 'l', 'l', 'o']
    >>> z = ["hello"]
    >>> z
    ['hello']
    >>>
