The “encode()” method encodes the string. The error AttributeError: ‘int’ object has no attribute ‘encode’ occurs when you call the “encode()” method on an integer object. To solve this error, we use the “repr()” method and the “str()” method to convert integer objects to string form.
What causes the AttributeError: ‘int’ object has no attribute ‘encode’ in Python?
The simplest way to encode a string in Python is to use the “encode()” method. The syntax of this method is as follows:
Syntax:
string.encode(encoding, errors)Parameter:
encoding: is a string specifying the type to encode. If this parameter is not passed, the default will be UTF-8
errors: is a string specifying the error.
Return Value:
This method will return the string in encoded form
This error occurs because we call the “encode()” method on an object of type integer. Because an integer object has no “encode()” method. This method can only be called on string data types. If you want to convert from integer to string, you can use the “unicode()” method, and then you can use the “encode()” on it.
Example:
price = 250
# Use "encode()" method on integer object
print(price.encode('utf-8'))Output:
AttributeError: 'int' object has no attribute 'encode'Errors can also occur when you call the “encode()” method on a variable that receives an integer return value.
Example:
def getPrice():
return 250
# Variable "price" is integer data type received from function "getPrice()"
price = getPrice()
print(price.encode('utf-8'))Output:
AttributeError: 'int' object has no attribute 'encode'Solution for the AttributeError: ‘int’ object has no attribute ‘encode’
To resolve this error, we need to monitor the variable assignment process to ensure that the “encode()” method is called on the string data type. We can convert the data type to be encoded to the string data type.
Using “repr()”
repr() is a method to represent objects as strings. This method is often used during development. This function can handle Unicode, utf, null, and int. The strength of this function is that it does not lose value when converting.
Example:
price = 250
# Use "repr()" function to represent integer objects as strings
price = repr(price)
print(price.encode('utf-8'))Output:
b'250'Using “str()”
If you want to get the encoded version of the number, you first convert the number to a string and then call “encode()” method.
Example:
price = 250
# Use "str()" function to convert integer to string
price = str(price)
print(price.encode('utf-8'))Output:
b'250'Read more of this article to learn more about the issue.
Summary
Through the article, we have found the cause and solution of the problem together. To avoid this error, you must monitor the data changes of the variable and remember to convert to the string before calling the “encode()” method. Hope you get it fixed soon.
