The strings passed in are uppercase, while the uppercase letters A through Z Unicode values are in ascending order. The core of the cryptographic algorithm is the first 13 alphabetic Unicode values plus 13, and the last 13 alphabetic Unicode values minus 13 from the alphabet back.

The collation of PYTHON3 code!!!PY Encoding Ultimate EditionSpeaking of Python coding, it is a very sad sentence. Counted, repeated two months of tossing and counting. Fortunately, finally combed clear. As a communist, be sure to share it with everyone. If you're still having headaches because of coding, then come with me. Let's uncover the truth of the PY code!What is a code?The basic concept is simple. First, we start with a piece of information, the message, that the message exists in a human
?? Need to implement Python to read the QR code, barcode information in the picture. The previous period of time research using Zbarlight module, a lot of effort to install debugging, but found some pictures are not read correctly, and if the image of the two-dimensional code tilt, can not read, can not meet the requirements. Yesterday, trying to try zxing, download zxing module after installation, but has been an error. Open Module Source code careful analysis, the original module is called by
request header sent together. Here want to say a few more, for Get method, no request entity, contains the data URLs are in the request header, the reason why the URL encode,I personally feel the reason is: for the request to the end of the head is to encode the iso-8859-1 encoding into binary 101010 .... Pure data in the Internet transmission, if the direct containing Chinese and other special characters do ISO-8859-1 encoding will lose information, so first do the URL encode is necessary.
What file is HQX?
The hqx file is the Macintosh BinHex 4.0 file, a hexadecimal text file format that, in the Macintosh, can be decoded using the StuffIt Expander pair. HQX, which can be decoded in Windows using BinHex 13. Most of the Macintosh files currently appear in the. hqx, and some are in the hex format, but rarely in the bin format for Macintosh files. The hqx file is the Macintosh BinHex 4.0 file,

10.Caesars Cipher
Let God be God, Caesar's Caesar.
Here we introduce the world's most popular Caesar password Caesar cipher, also known as the shift password.
The shift cipher, or the letter in the cipher, is shifted according to the specified number.
A common case is the ROT13 cipher, which shifts 13 positions. By ' A ' ↔ ' N ', ' B ' ↔ ' O ', and so on.
Write a ROT13 function that implements the input encryption string and outputs the decryption string.
All letters are

10. Caesars Cipher
Let God go to God, and Caesar go to Caesar.
Next, we will introduce the world's popular Caesar password Caesar cipher, also known as shift password.
Shift the password, that is, the letters in the password will be shifted according to the specified number.
A common case is the ROT13 password, where letters are moved to 13 locations. By 'A' N ',' B 'O', and so on.

The BitmapDecode example mainly describes the Android platform's image decoding function. The Android platform supports PNG and JPEG image formats and GIF animation.
The Android API mainly uses BitmapFactory (PNG or JPEG static image) and Movie (GIF animation) to decode images ).

We need to create a variable to hold we decode the JSON data and then calljson.Unmarshal方法,并把需要解码的数据和这个变量的指针,传递给该函数。
We must first create a place where the decoded data would be Stored,and call json.Unmarshal passing it a of []byte JSON data and a P Ointer tom
err := json.Unmarshal(b, m)
If B contains a valid JSON data and the structure matches m, then err will return nil, and the decoded

This is a native Python serialization method. However, JSON has become popular in recent years, and Python has added support for it. Now you can use JSON for codec.
The code is as follows:
Import json
Variable = ['hello', 42, [1, 'two'], 'apple']Print "Original {0}-{1}". format
