byte indices must be integers or slices

这个错误通常是由于在Python中使用了不正确的索引方式。在Python中，索引必须是整数或切片对象。如果您使用了非整数或非切片对象作为索引，则会出现此错误。例如，如果您尝试使用浮点数作为索引，则会出现此错误。正确的做法是使用整数或切片对象作为索引。

byte indices must be integers or slices, not str

This error occurs when you try to use a string as an index for a byte array or bytes object. Byte indices must be integers or slices, not strings.

For example, if you have a bytes object and you try to access a specific byte using a string index:

my_bytes = b'hello world'
my_index = '2'

print(my_bytes[my_index])

You will get the "TypeError: byte indices must be integers or slices, not str" error because `my_index` is a string and not an integer.

To fix this error, make sure that you are using integer indices when accessing bytes in a bytes object. If you need to convert a string index to an integer, you can use the `int()` function:

my_bytes = b'hello world'
my_index = '2'

print(my_bytes[int(my_index)])

This will output the byte at index 2, which is the letter "l".

TypeError: byte indices must be integers or slices, not str

This error occurs when you try to access a byte object using a string index. Byte objects are sequences of bytes, and their elements can only be accessed using integer indices or slices.

For example:

my_bytes = b"hello"
print(my_bytes[0])  # This will output: 104
print(my_bytes[1:3])  # This will output: b"el"
print(my_bytes["h"])  # This will raise a TypeError

In the last line of the code, we are trying to access a byte object using a string index ("h"), which is not allowed. To fix this error, you need to use integer indices or slices when accessing byte objects.
