Python String encode() Method (2024)

FAQs

What does encode() do in Python? ›

The encode() method encodes the string, using the specified encoding. If no encoding is specified, UTF-8 will be used.

encode() and . decode() methods, transmit or store encoded data, validate your decoded data, and handle errors.

If no parameters are specified, then the Python string encode() function uses its default values. For the encoding parameter, the default value is UTF-8, and for the errors parameter, the default value is strict.

Python Strings encode() method

Python String encode() converts a string value into a collection of bytes, using an encoding scheme specified by the user.

There are various encodings present which treat a string differently. The popular encodings being utf-8, ascii, etc. Using the string encode() method, you can convert unicode strings into any encodings supported by Python. By default, Python uses utf-8 encoding.

encode() method takes a string as input, and returns a Uint8Array containing the text given in parameters encoded with the specific method for that TextEncoder object.

Encoding data is typically used to ensure the integrity and usability of data and is commonly used when data cannot be transferred in its current format between systems or applications. Encoding is not used to protect or secure data because it is easy to reverse.

The ENCODE function performs a one-way encoding operation that you cannot reverse. It is useful for storing scrambled copies of passwords in a database.

For example, “abba” will be encoded as “bbaa”. Note that the middle character is the first character of the two middle characters when the length of the string is even.

For example, you may realize you're hungry and encode the following message to send to your roommate: “I'm hungry. Do you want to get pizza tonight?” As your roommate receives the message, they decode your communication and turn it back into thoughts to make meaning.

How to encode input in Python? ›

To encode data using base64 in Python, you can use the base64 module's b64encode() function, like print(base64. b64encode(data)) . This function takes in binary data as input and returns the base64 encoded version of the input data. In this example, we import the base64 module and define a byte string data .

Since encode() converts a string to bytes, decode() simply does the reverse. This shows that decode() converts bytes to a Python string. Similar to those of encode() , the decoding parameter decides the type of encoding from which the byte sequence is decoded.

The default encoding of Python source files is UTF-8. JSON, TOML, YAML use UTF-8. Most text editors, including Visual Studio Code and Windows Notepad use UTF-8 by default.

UTF-8 is one of the most commonly used encodings, and Python often defaults to using it. UTF stands for “Unicode Transformation Format”, and the '8' means that 8-bit values are used in the encoding.

In computers, encoding is the process of putting a sequence of characters (letters, numbers, punctuation, and certain symbols) into a specialized format for efficient transmission or storage. Decoding is the opposite process -- the conversion of an encoded format back into the original sequence of characters.

The encode command assigns a number to each different string, starting with the number 1 and continuing on (2, 3, 4, etc), while applying a value label to each number. The decode command will convert a numeric variable to a string variable when that variable has a value label attached to it.

UTF refers to the standard Python encoding, and 8 refers to the 8-bit units used in character encoding. UTF-8 is a standard and efficient encoding of Unicode strings that represents characters in one-, two-, three-, or four-byte units.
