我一直在努力创建一个包含行号和行的元组列表,但我只想枚举非空行
这让我得到了我想要的东西
counter = 0
line_list = []
for line in open(file).readlines()
if line.strip() == '':
continue
line_list.append((counter,line.strip()))
counter +=1
当我这样做时
line_list = [(index,line) for index, line in \
enumerate(open(file).readlines() if line.strip() != 0]
正如预期的那样(在我想到之后)读取每行的索引进展因此我在读取的每个空白行的数字上都有差距
我也试过
counter = 0
line_list = [(counter,line) for line in open(file).readlines() \
if line.strip != '' counter +=1]
这给了我一个语法错误
以下是原始文件类型的示例
'Some words are in a line \n'
' maybe another line with more words\n'
'\n'
'\n'
'See the one or more blank lines\n'
'maybe more or less word\n'
'\n'
'\n'
'lots of lines with text\n'
答案 0 :(得分:3)
枚举非空行:
[(index, line) for index,line in enumerate(l for l in open(file) if l.strip())]
答案 1 :(得分:2)
line_list = list(enumerate(line for line in open(file) if line.strip()))
