如何解决 byte indices must be integers or slices, not str
时间: 2023-10-31 17:52:50 浏览: 162
这个错误通常是在使用索引时将字符串传入导致的。在 Python 中,字符串是不可变的,而索引必须是整数或切片,因此当传入字符串时会出现此错误。
要解决此错误,请确保您正在使用整数或切片来索引对象,而不是字符串。如果您仍然遇到问题,请检查您的代码,以确保您正在正确地使用索引。您可以在代码中打印出相关对象来进行调试,找到导致此错误的代码行。

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".
解决list indices must be integers or slices, not str
这个错误通常是由于在Python中使用了字符串作为列表的索引而引起的,而列表的索引只能是整数或者切片。解决这个问题的方法是确保在使用列表索引时使用整数或者切片而不是字符串。你可以检查你的代码,找出在哪里使用了字符串作为列表的索引,并将其修改为合适的整数或者切片。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
