子串处理和字符串提取

Question

我想从足球推文中提取角的数量。不同的用户以不同的方式提及数字。

我不是很强大的python字符串处理，但试图编写逻辑提取corners值。如果有人告诉我是否写了任何错误的逻辑，或者考虑所有情况的更好方法，我真的很感激。

# I get wrong corner number if it is two digit value 
def getCorners(self, text): 
    # print text 
    try: 
     if 'corner' in text: 
      print text 
      corner = "Yes"     
      #To check the case: digit+ corner (it should be mentioned as over <digit> corners) 
      if str(text.find('+ corner')-1).isdigit(): 
       corner_pos = text.find('+ corner')-1 
       nos_corners = text[corner_pos] 
       corner = str(nos_corners) + ' corners' 
       # if text.find('+ corners') == (corner_pos-10): 
       if '+corner' in text: 
        corner = "over " + str(nos_corners) + 'corners' 
      elif str(text.find(' corner')-1).isdigit(): 
       corner_pos = text.find('+ corner')-1 
       nos_corners = text[corner_pos] 
       corner = str(nos_corners) + ' corners' 
      print corner + "\n" 
     else: 
      corner = "None"   
    except: 
     pass 

我仍然在试图改善逻辑，但任何建议，以改善逻辑或大加赞赏鸣叫

我希望这会帮助你的

类型一些Python功能。

loadData = open("file.txt", "r") 
loadData = loadData.readlines() 


def check(data): 
    for i in range(0, len(data)): 
     if data[i] == 'corners' and len(data[i - 1]) < 3: 
      print(data[i - 1]) 


for data in loadData: 
    dataSplitted = data.split() 
    check(dataSplitted) 

而结果将是：
