Abstract : 

       Commercial exploitation over the past two hundred years drove     
       the great Mysticete whales to near extinction. Variation in     
       the sizes of populations prior to exploitation, minimal       
       population size during exploitation and current population      
       sizes permit analyses of the effects of differing levels of      
       exploitation on species with different biogeographical       
       distributions and life-history characteristics. Dr. Stephen     
       Palumbi at the University of Hawaii will study the genetic      
       population structure of three whale species in this context,     
       the Humpback Whale, the Gray Whale and the Bowhead Whale. The     
       effect of demographic history will be determined by comparing     
       the genetic structure of the three species. Additional studies     
       will be carried out on the Humpback Whale. The humpback has a     
       world-wide distribution, but the Atlantic and Pacific       
       populations of the northern hemisphere appear to be discrete     
       populations, as is the population of the southern hemispheric     
       oceans. Each of these oceanic populations may be further      
       subdivided into smaller isolates, each with its own migratory     
       pattern and somewhat distinct gene pool. This study will      
       provide information on the level of genetic isolation among      
       populations and the levels of gene flow and genealogical      
       relationships among populations. This detailed genetic       
       information will facilitate international policy decisions      
       regarding the conservation and management of these magnificent     
       mammals."""

Answer 1

。あなたが望む項目のそれぞれについて、正しい正規表現パターンと

例えばラインから値179720123を取得する：

Total Amt. : $17972(Estimated) 

あなたはこれを行うことができます。

は

# first look for matching pattern (Total Amt. : $xxx) where xxx are some numbers 
total_amt_line=re.findall('Total Amt\.\s+: \$[0-9]*', data) 

print(total_amt_line) 
>>> ['Total Amt. : $179720'] 

# if there are any matches found extract any number values out of it 
if len(total_amt_line) > 0: 
    total_amt = re.findall('[0-9]+', total_amt_line[0]) 
    print(total_amt) 
    >>> ['179720'] 

Answer 2

あなたが探しているパターンがある：r"\$(\d+(?:\.\d+)?)"。
