The coding problem of Python has never been solved, and finally it is clear from this blog post today.Original address: http://nedbatchelder.com/text/unipain.htmlAddress:

Class SplitString { String SplitStr; Int SplitByte; Public SplitString (String str, int bytes) { SplitStr = str; SplitByte = bytes; System. out. println ("The String is: '" + SplitStr + "'; SplitBytes =" + SplitByte ); } Public void SplitIt () { Int

Picture because the file is relatively large, commonly used pictures such as reading the database or file to increase the system load. The use of caching methods can increase

/*** Description: Get the length of the string in bytes;* @ Versions 0.2;* @ Return returns the length of the string in bytes (for example, "12 to 12", the length of the string is 6 );*/String. Prototype. getlength = function (){VaR text = This.

Character encoding in Python is a common topic, and many articles have been written in this field. Some people are also cloud, and some are well written. Recently, I saw a video from a well-known training institution talking about this issue again,

When the protocol is resolved. Always encounter a variety of data conversion problems, from binary to Decimal, from byte string to integer, etc.Not much nonsense on. Directly on the sampleBinary conversions between integers: 10-in-turn

Chinese QuestionsHow to write a Chinese program: Use Chinese to declare the encoding in the first line #encoding =utf-8 The file is saved in utf-8 encoded format , the Chinese string in the file needs U, for example: U ' Chinese '

>>> "Hello". Encode ("hex")' 68656c6c6f ' The corresponding can also >>> ' 68656c6c6f ' decode ("hex")' Hello ' I checked the manuals, and these codec are available. Codec Aliases Operand type Purpose

>>> "Hello". Encode ("hex") ' 68656c6c6f ' The corresponding can also >>> ' 68656c6c6f '. Decode ("hex")' Hello ' Check the manuals, and these codec are available. Codec Aliases Operand type Purpose Base64_codec

During network programming, you often need to print the received data in hexadecimal format for easy viewing. Today we found that there is such a simple method in Python.   >>> "Hello". encode ("hex ")'68656c6c6f'   You can also >>> '68656c6c6f'.

This problem often occurs in our programs. Testing in WINXP is normal, and this problem occurs on the server (Linux operating system.1. Because the mail subject of the program I wrote is written in the configuration file (. properties), and then use
