Problem: One day is going to clear all your browsing the history, and you come a idea:you want to the figure out what yo ur most valued site is. Every site is given a value which equals to the sum of ASCII values of all characters in the URL. For example aa.cc have value of 438 because 438 = 97 + 97 + 46 + 99 + 99. You just need to print the largest value amongst all values of sites.Things is simplified because you found it all entries in your browsin

To make a requirement, the password settings for the visible special characters are supported. First, you need to get all the visible special characters. Search the online ASCII character table and copy it to the text file Vschars.txt:00000nul1004064@01011soh1014165a02022stx1024266b03033etx1034367c04044eot1044468d05055enq1054569e06066ack1064670f07077bel1 074771g10088bs1104872h11099ht1114973i120a10nl1124a74j130b11vt1134b75k140c12ff1144c76l150d13er1154d

ASCII is a character set, including uppercase and lowercase English letters, numbers, and control characters. It is represented in one byte and ranges from 0 to 127. Unicode is divided into UTF-8 and UTF-16. UTF-8 variable length, up to 6 bytes, less than 127 characters are represented in one byte, the same as the results of the ASCII character set, english text under

ASCII is a byte store in English and special characters, does not support the processing of Chinese. Unicode occupies two bytes and can be stored in Chinese. The Utf-8 occupies three bytes and can be converted in English and Chinese according to the contents of the storage.Python interpreter is not supported in Chinese, the default is the ASCII format storage, so generally at the beginning of the program to

Once the Python installation is successful, the default encoding is ASCII, which is usually reported when non-ASCII code is present in the program.The way to do this is to change the Python default encoding to Uft-8Create a new file sitecustomize.py in the lib\site-packages in the Python installation file with the following code:#encoding =utf8Import SysReload (SYS)Sys.setdefaultencoding (' UTF8 ')Then rest

When installing the scrapy package through pip, the following error occurs: UnicodeDecodeError: 'ascii 'codec can't decode byte 0 ......, An error occurred while installing the scrapy package through pip: (Exception: Traceback (most recent call last ): ......

Django view functions often encounter errors similar to 'ascii 'codec can't decode byte 0xef in position 0: ordinal not in range (128. Before resolving the error, you must first understand the difference between Unicode and UTF-8.Unicode refers to a world code table ". UTF-8 is the encoding method stored in this code table. Unicode does not have to be compiled into bytecode storage by UTF-8. You can also use other methods such as UTF-16 and utf-7. At

Currently, the most widely used character set and Its Encoding in computers are American Standard Code for Information Interchange (American Standard Code for Information Interchange) developed by the National Bureau of Standards (ANSI ), it has been set as an international standard by the International Organization for Standardization (ISO), known as the ISO 646 standard. Applies to all Latin letters, ASCII code can be in the form of a 7-digit code

Unicode conversion ascii code, wchar * To char *, unicodewchar For the ascii code, char is actually the first bytecode of the unicode code wchar, For example, wchar [20] = "qqqq"; in the memory, the code is actually char's 'q'' \ 0', so if we write the unicode code to convert it to an ascii char, you only need to take the first byte, and I have written a function
