Typeerror a bytes like object is required not str

Typeerror a bytes like object is required not str : How to Fix?

Typeerror a bytes like object is required not str error occurs when we compare any ‘str’ object with the ‘byte’ type object. The best way to fix this error is to convert them into ‘str’ before comparison or any other operation.

 

Typeerror a bytes like object is required not str ( Cause) :

The clear reason is the compatibility of str objects with Byte type object. But let’s understand it with some coding examples.

a=("Hi This is byte encoded").encode()
b="Hi"
if b in a:
  print("Sub String")

Here We have encoded the string a and b is not encoded. Now when we use “in” operator a is a byte type object. We get the same error.

Typeerror a bytes like object is required not str ( Solution) :

See this error is due to object compatibility. So let’s convert “str” object to byte. There are many ways to achieve it.

1. Encode “str” object to byte object-

In Continuation with the above example. Let’s encode the str object to Byte before “in” operator.

a=("Hi This is byte encoded").encode()
b=("Hi").encode()
if b in a:
  print("Sub String")

Now run the above code.

2. Decode the Byte Object to ‘str’  :

Quite Simple. As earlier, we have converted str to byte. Here we are doing the opposite. Here we will decode the Byte to str.

a=("Hi This is byte encoded").encode()
b=("Hi")
if b in a.decode():
  print("Sub String")

3. Typecast Byte object to ‘str’ :

Firstly, Let’s see the code.  Here we can typecast the Byte type object to str.

a=("Hi This is byte encoded").encode()
b=("Hi")
if b in str(a):
  print("Sub String")

 

4. Typecast Byte object to ‘str’ :

In a similar way above, We can also convert str objects into a Byte object. Please refer to the below code.

a=("Hi This is byte encoded").encode()
b=bytes("Hi","utf-8")
if b in a:
  print("Sub String")

Conclusion :

Well, I think this article is helpful in resolving the bug. See there may so many scenarios where we get the same error. But the root cause will always be type mismatch. So you need to convert them as per your compatibility.
