I was reading about bytes and byte array's. I read that byte arrays mutable types!
so, when i am trying to modify it i am getting an error saying integer is required Am i missing something here? The following is my code and the error
z=bytearray("hello world","utf-8")
z[0] ="H"
i got the following error
TypeError Traceback (most recent call last) in () ----> 1 z[0]="H"
TypeError: an integer is required
As the docs say:
The bytearray type is a mutable sequence of integers in the range 0 <= x < 256.
The reason you can create it with a string as each character is converted to its ASCII integer value. So when assigning 'H' you actually mean to assign 72.
If you want to be able to assign chars, then just pass each one into ord() first.
bytearray. If you know from C or similar, an array is (normally) a sequence of integers that can be indexed. A string is normally seen in higher-level languages but at the fundamental level, it is an array of integers representing the ASCII characters (a UTF-8 subset). So if you want a string where you can change the characters by index, you would be better of with a list of individual characters e.g: list("hello there") which gives ['h', 'e', 'l', ...] so then you can modify chars by index as lists are mutable.string (for prettier printing etc.) then you can use the join method on an empty string: ''.join(lst).
z[0] = ord('H')?
