从文件中选择特定行

我有一个带条目的文本文件

• Row totalEven

• 0 125000

• Row totalEven

• 0 340000
• 1 159000

• Row totalEven

• 0 1360000
• 1 1440000
• 2 1440000
• 3 1380000
• 4 1350000
• 5 1440000
• 6 1440000
• 7 1440000
• 8 1440000
• 9 1422000
• 10 180000
  它就像6000多行一样。我需要从第二列获得数字并总结它们。选择这样一条线，

f = open(afile,'r')
for i, l in enumerate(f):

if l=="*    Row   * totalEven *" and (l=='************************'):                                                                                                                            
    continue
else:
    nEv = l.split('*')[2] #here it chooses the 2nd column of the line

但是它给了我一个带有第三列数字的输出，空行和带有“totalEven”的行。然后我也尝试使用，if re.search(' Row totalEven *', l):但它给出了这个错误
