Example text

The boolean objects have their own special logic operators: and, or, and not. These operators can short-circuit the expression evaluation. In the case of and, if the lefthand side expression is False, the final result must be False; therefore, the righthand side expression is not evaluated. In the case of or, the rules are reversed. If the left-hand side expression is True, the final result is already known to be True, so the right-hand side expression is skipped. = 0 and sum/count Let's look closely at the final expression.

We have to distinguish between two contexts for string literals: • Ordinary Python Strings: The default case is to have Python examine the string and replace escape sequences with otherwise unprintable characters. When we write '\u03c0\xd7r\xb2', we expect Python to replace the various escapes with proper Unicode characters; the escapes really mean this: 'π×r²'. Sometimes, we'll use the u' prefix for this: u'\u03c0\xd7r\xb2'. • Regular Expression Strings: When writing regular expressions, we do not want Python messing with the \ characters.

Html. Note that the documentation is older than the actual package as it says (in red) Python 3 is not supported. However, the pdfminer3k project clearly states that pdfminer3k is a Python 3 port of pdfminer. While the software may have been upgraded, some of the documentation still needs work. 6. The lex and yacc summary may not be too helpful for most of the agents. These terms refer to the two classic programs that are widely used to create the tools that support software development.
