拆分问题 [英] problem with split
问题描述
道歉，如果我烦恼和间距（谷歌）
def csdInstrumentList（from_file）：
"返回.csd工具列表和任何
工具后的注释行
infile = open（from_file，''r''）
temp_number = 0
for infile：
如果''instr''在行：
s = re.split（r''''，line，3）
instr_number = s [1]
返回instr_number
我接近我想要的变化，但是我
似乎无法支付
得到3行拆分和instr_number [array] = s [1]似乎给了我一个错误。
来自我试图分成三行的数据看起来像
这个
instr 83;评论将是这里
我希望在数组中返回注释，并在
数组中返回instr_number。
< BLOCKQUOTE> P.S。这是我需要完成的以释放csoundroutines

让我看看我是否理解你想要的东西：如果有一行
以instr开头（最好用line.startswith测试） （''instr''）:)），你
想要数字和后来的commen。我用这个
目的的正则表达式。在您的情况下：
导入重新
< snip>
如果是line.startswith （''instr''）：
p = re.compile（r''（\d +）\s +;（。*）
'' ）
m = p.search（line）
return（m.group（1），m.group（2））
我当然返回了一个元组;你可能希望改变它。
BTW，谢谢 - 我刚学会了如何在Python中使用re。
apologies if I annoy and for spacing (google)
def csdInstrumentList(from_file):
"Returns a list of .csd instruments and any comment lines after the
instrument"
infile = open(from_file, ''r'')
temp_number = 0
for line in infile:
if ''instr'' in line:
s = re.split(r'' +'',line,3)
instr_number = s[1]
return instr_number
I am coming pretty close to what I want with variations on theis but I
cant seem to
get 3 lines with the split and instr_number[array] = s[1] seems to give
me an error.
the data from the line I am trying to split in three would look like
this
instr 83 ;comment would be here
I want comment returned in an array and instr_number returned in an
array.
p.s. this is the one I need to finish to release the csoundroutines

array.Let me see if I understand what you want: if there is a line that
starts with instr (best tested with line.startswith(''instr'') :)), you
want the number and the commen afterwards. I used regexes for this
purpose. In your case:
import re
<snip>
if line.startswith(''instr''):
p = re.compile(r''(\d+)\s+;(.*)
'')
m = p.search(line)
return (m.group(1), m.group(2))
I returned a tuple of course; you may wish to change that.
BTW, thank you -- I just learned how to use re''s in Python.
