您的程序可以通过分解

temp = []
temp.extend(each_line.split(','))

从每个elif开始，改为在elif节的上方或下方写一次。你知道吗

通常，这样的解析可以通过将源代码拆分成块，然后将这些块用作函数字典的键来改进（或者，在您的例子中，字符串字典也可以工作，因为所有的终端函数只在它们的字符串中不同）。有关示例，请参见实例this blog post。只要输入是有规律的，这可能是实现良好重构的最佳途径。与流控制不同，数据结构是围绕将输入映射到输出的数据结构构建一个小程序，而不是在程序代码中嵌入映射的大程序。你知道吗

您可以对以下值使用regex match，而不是测试每个案例：

m = re.search('([0-9]+)bps', each_line)
if m is None:
    bps = None
else:
    bps = int(m.group(1))

m = re.search('([0-9]+)ch', each_line)
if m is None:
    channels = None
else:
    channels = int(m.group(1))

m = re.search('([0-9]+)kHz', each_line)
if m is None:
    bandwidth = None
else:
    bandwidth = int(m.group(1))

# if still needed
audio = '%ich %ikHz %ibps' % (channels, bandwidth, bps)

如果整行的格式与我看到的here相同，也可以匹配整行：

patt = '''MainSound\s*\(.*([0-9]+) channels, ([0-9]+) kHz, ([0-9]+) bps, audio\)'''
m = re.search(patt, each_line)
if m:
    channels, bandwidth, bps = m.groups()

或者，如果您确切地知道行的外观，您可以使用PyParsing。你知道吗
