Python：在csv.DictReader中跳過標註＃的註釋行

Question

處理具有csv.DictReader的CSV文件非常棒 - 但我有註釋行（在行首以散列表示）中的CSV文件，例如：

 
# step size=1.61853 
val0,val1,val2,hybridisation,temp,smattr 
0.206895,0.797923,0.202077,0.631199,0.368801,0.311052,0.688948,0.597237,0.402763 
-169.32,1,1.61853,2.04069e-92,1,0.000906546,0.999093,0.241356,0.758644,0.202382 
# adaptation finished 

csv模塊doesn't include any way to skip such lines。

我可以很容易地做一些黑客行爲，但我想有一種很好的方式來將csv.DicReader包裝在其他一些迭代器對象周圍，這些對象會預處理以放棄行。

其實這很好地工作與filter：

import csv 
fp = open('samples.csv') 
rdr = csv.DictReader(filter(lambda row: row[0]!='#', fp)) 
for row in rdr: 
    print(row) 
fp.close()
