AttributeError: 'int' object has no attribute 'encode' #

The Python "AttributeError: 'int' object has no attribute 'encode'" occurs when we call the encode() method on an integer. To solve the error, make sure the value you are calling encode on is of type string.

attributeerror int object has no encode

Here is an example of how the error occurs.

main.py
my_str = 'hello world' my_str = 123 # ⛔️ AttributeError: 'int' object has no attribute 'encode' print(my_str.encode('utf-8'))

We reassigned the my_str variable to an integer and tried to call the encode() method on the integer which caused the error.

If you print() the value you are calling encode() on, it will be an integer.

To solve the error, you need to track down where exactly you are setting the value to an integer in your code and correct the assignment.

To solve the error in the example, we would have to remove the reassignment or correct it.

main.py
my_str = 'hello world' print(my_str.encode('utf-8')) # 👉️ b'hello world'

If you are trying to get the encoded version of a number as a bytes object, convert the integer to a string before calling encode().

main.py
my_num = 1234 result = str(my_num).encode('utf-8') print(result) # 👉️ b'1234'

The str.encode method returns an encoded version of the string as a bytes object. The default encoding is utf-8.

You might also be assigning the result of calling a function that returns an integer to a variable.

main.py
def get_string(): return 100 my_string = get_string() # ⛔️ AttributeError: 'int' object has no attribute 'encode' print(my_string.encode('utf-8'))

The my_string variable gets assigned to the result of calling the get_string function.

The function returns an integer, so we aren't able to call encode() on it.

To solve the error, you have to track down where the specific variable gets assigned an integer instead of a string and correct the assignment.
