16. anUnicode. encode ('encoding') results in a string object and can be called on a unicode object. aString. decode ('encoding') results in an unicode object and can be called on a string, encoded in given encoding. Some more explanations: You can create some unicode object, which doesn't have any encoding set.
It is also compatible with Python 2. the only incompatibility with py2 is .encode() returns a bytes object instead of a str object (or unicode object in the OP's case). Encode () returns an 8-bit string in both cases. It's called "str" in Python 2 and "bytes" in Python 3, but both are 8-bit strings.
229. Encoding transforms data into another format using a scheme that is publicly available so that it can easily be reversed. Encryption transforms data into another format in such a way that only specific individual (s) can reverse the transformation. For Summary -. Encoding is for maintaining data usability and uses schemes that are publicly ...
URL Encoding does a similar thing for string values in a URL like changing. to. HTML encoding and URL encoding do fundamentally different things. If you HTML encode, for instance, 'hello world' and try to add it to a url, you will get an invalid url. Both are important, and should be used for different situations.
Even though encodeURIComponent does not encode all characters, decodeURIComponent can decode any value between %00 and %7F. Note: It appears that if you try to decode a value above %7F (unless it's a unicode value), then your script will fail with an "URI error".
Generally, encoding/decoding JSON refers to the process of actually reading/writing the character data to a string or binary form. Marshaling/Unmarshaling refers to the process of mapping JSON types from and to Go data types and primitives. Actual encoding can include things like serializing unicode characters for example.
Note that if the function was being used correctly in the first place, there is no need to guess the encoding: utf8_encode worked only with ISO 8859-1. Also note that guessing the encoding is not something you can rely on, because the same string of bytes can be valid in many encodings, and the computer has no way to detect the intention of the ...
json_encode() was roughly 80.52% faster than serialize() unserialize() was roughly 6.02% faster than json_decode() JSON string was roughly 53.04% smaller than Serialized string. We can conclude that JSON encodes faster and results a smaller string, but unserialize is faster to decode the string.
137. Both Base64 and Base64url are ways to encode binary data in string form. You can read about the theory of base64 here. The problem with Base64 is that it contains the characters +, /, and =, which have a reserved meaning in some filesystem names and URLs. So base64url solves this by replacing + with - and / with _.
Here is an example of doing sequence classification using a model to determine if two sequences are paraphrases of each other. The two examples give two different results. Can you help me explain why tokenizer.encode and tokenizer.encode_plus give different results? Example 1 (with .encode_plus()):
