...strings The usual boolean operators and and or can be used to combine expressions, and parentheses are supported for grouping. The pseudo-grammar is MARKER: EXPR [(and|or) EXPR]* EXPR: ("(" MARKER ")") | (STREXPR|VEREXPR) STREXPR: STRING [STRCMPOP STREXPR] STRCMPOP: ==|!=|in|not in VEREXPR: VERSION [VERCMPOP VEREXPR] VERCMPOP: (==|!=|<|>|<=|>=) SUBEXPR is either a Python string (such as 'win32') or one of the Strings marker variables listed below. VEREXPR is a PEP 440 version iden...
...strings in such a way that allows recreation of the original byte string. Rationale The C char type is a data type that is commonly used to represent both character data and bytes. Certain POSIX interfaces are specified and widely understood as operating on character data, however, the system call interfaces make no assumption on the encoding of these data, and pass them on as-is. With Python 3, character strings use a Unicode-based internal representation, making it difficult to ignore the en...
...string objects in namespace dictionaries; identifiers with non-ASCII characters would be represented as Unicode strings. Implementation The following changes will need to be made to the parser: If a non-ASCII character is found in the UTF-8 representation of the source code, a forward scan is made to find the first ASCII non-identifier character (e.g. a space or punctuation character) The entire UTF-8 string is passed to a function to normalize the string to NFKC, and then verify that it foll...

...string from the console, write a string to the console. I decided not repeat this mistake in Python. Besides this intention, I had a number of other ideas for improvement over ABC, and was eager to try them out. For instance, ABC's powerful data types turned out to be less efficient than we hoped. There was too much emphasis on theoretically optimal algorithms, and not enough tuning for common cases. I also felt that some of ABC's features, aimed at novice programmers, were less d...
...algorithm. Some examples are CALG_3DES and CALG_AES_256, which refer to the bulk encryption algorithm used in a cipher suite, CALG_DH_EPHEM and CALG_RSA_KEYX which refer to part of the key exchange algorithm used in a cipher suite, CALG_SHA1 and CALG_MD5 which refer to the message authentication code used in a cipher suite, and CALG_ECDSA and CALG_RSA_SIGN which refer to the signing portions of the key exchange algorithm. This can be thought of as the half of OpenSSL's functionality that SecureT...
