carefully. Definition: Exceptions are a means of breaking out of the normal flow of control of a code block to handle errors or other exceptional conditions. Pros: The control flow of normal operation code or catch Exception or StandardError, unless you are re-raising the exception or in the out- ermost block in your thread (and printing an error message). Python is very tolerant in this regard and except: try/except block. The larger the body of the try, the more likely that an exception will be raised by a line of code that you didn’t expect to raise an exception. In those cases, the try/except block hides

compression  dedicated sampling schemes and estimators  Initially slow compressed operations  cache-conscious operations, selected operations with better asymptotic behavior Structure of Scientific techniques struggle to achieve both good compression ratios and fast decompression speed to enable block-wise uncompressed operations. % 3. Say what your solution achieves Hence, we initiate work on compressed directly on the compressed representations. We contribute effective column compression schemes, cache-conscious operations, and an efficient sampling-based compression algorithm. Our experiments show

spacing Imports are ordered as follows: 1. All static imports in a single block. 2. All non-static imports in a single block. If there are both static and non-static imports, a single blank line separates separates the two blocks. There are no other blank lines between import statements. Within each block the imported names appear in ASCII sort order. (Note: this is not the same as the import statements being sequentially, with no intervening members (not even private ones). 4 Formatting Terminology Note: block-like construct refers to the body of a class, method or constructor. Note that, by Section 4.8.3.1

own line; a closing curly brace should always go on its own line. You may omit curly braces when a block consists of a single statement; however, you must consistently either use or not use curly braces c(0, 0.06) } xor (but not both) if (is.null(ylim)) ylim <- c(0, 0.06) Always begin the body of a block on a new line. BAD: if (is.null(ylim)) ylim <- c(0, 0.06) if (is.null(ylim)) {ylim <- c(0, 0.06)}
