The last two complications may occur with or without preceding exacerbation o f the angina pectoris. As with other beta-blockers, when discontinuation of atenolol tablet, USP, is planned, the patients should be carefully observed and advised to limit physical activity to a minimum. If the angina worsens or acute coronary insufficiency develops, it is recommended that atenolol tablet, USP be promptly reinstituted, at least temporarily.

生成器函数是一个实现管道机制的好办法。 为了演示,假定你要处理一个非常大的日志文件目录: foo/ access-log-012007.gz access-log-022007.gz access-log-032007.gz ... access-log-012008 bar/ access-log-092007.bz2 ... access-log-022008 假设每个日志文件包含这样的数据: 124.115.6.12 - - [10/Jul/2012:00:18:50 -0500] "GET /robots.txt ..." 200 71 210.212.209.67 - - [10/Jul/2012:00:18:51 -0500] "GET /ply/ ..." 200 11875 210.212.209.67 - - [10/Jul/2012:00:18:51 -0500] "GET /favicon.ico ..." 404 369 61.135.216.105 - - [10/Jul/2012:00:20:04 -0500] "GET /blog/atom.xml ..." 304 - ... 为了处理这些文件,你可以定义一个由多个执行特定任务独立任务的简单生成器函数组成的容器。就像这样: import os import fnmatch import gzip import bz2 import re def gen_find(filepat, top): ''' Find all filenames in a directory tree that match a shell wildcard pattern ''' for path, dirlist, filelist in os.walk(top): for name in fnmatch.filter(filelist, filepat): yield os.path.join(path,name) def gen_opener(filenames): ''' Open a sequence of filenames one at a time producing a file object. The file is closed immediately when proceeding to the next iteration. ''' for filename in filenames: if filename.endswith('.gz'): f = gzip.open(filename, 'rt') elif filename.endswith('.bz2'): f = bz2.open(filename, 'rt') else: f = open(filename, 'rt') yield f f.close() def gen_concatenate(iterators): ''' Chain a sequence of iterators together into a single sequence. ''' for it in iterators: yield from it def gen_grep(pattern, lines): ''' Look for a regex pattern in a sequence of lines ''' pat = re.compile(pattern) for line in lines: if pat.search(line): yield line 现在你可以很容易的将这些函数连起来创建一个处理管道。 比如,为了查找包含单词python的所有日志行,你可以这样做: lognames = gen_find('access-log*', 'www') files = gen_opener(lognames) lines = gen_concatenate(files) pylines = gen_grep('(?i)python', lines) for line in pylines: print(line) 如果将来的时候你想扩展管道,你甚至可以在生成器表达式中包装数据。 比如,下面这个版本计算出传输的字节数并计算其总和。 lognames = gen_find('access-log*', 'www') files = gen_opener(lognames) lines = gen_concatenate(files) pylines = gen_grep('(?i)python', lines) bytecolumn = (line.rsplit(None,1)[1] for line in pylines) bytes = (int(x) for x in bytecolumn if x != '-') print('Total', sum(bytes))
