当信息不存在时，是否可以使用findall - regex追加任何值？
我想解析文本并将其保存到dataframe。有时信息不存在，就像二手资料一样，那里没有关于座位1的信息，我想在字典中附加任何或任何值。

file = open(r'example_hands.txt','r')
lines = [i.strip('\n') for i in file]
tab2 = {'Seat1': [],'S1_stack': [], 'Seat2': [], 'S2_stack':[]}
for i in range(len(lines)):
tab2_2 = re.findall('Seat\s1\:\s(\w+)\s\(\$(\d+(\.\d+)?)\s',lines[i])
for t2_2 in tab2_2:
if tab2_2 is None:
tab2['Seat1'].append(None)
tab2['S1_stack'].append(None)
else:
tab2['Seat1'].append(t2_2[0])
tab2['S1_stack'].append(t2_2[1])
tab2_3 = re.findall('Seat\s2\:\s(\w+)\s\(\$(\d+(\.\d+)?)\s',linia[i])
for t2_3 in tab2_3:
tab2['Seat2'].append(t2_3[0])
tab2['S2_stack'].append(t2_3[1])目前，我无法在列表中添加任何值。有什么办法解决这个问题吗？有可能用re.findall吗？我想要这样的产出：

您可以修改以下原型，它确实从您的文件中提取了所有相关信息。
留给你做作业的唯一一点就是以一种表格的方式显示它。
import re
class PockerStarHand:
def __init__(self, handId, date, seats):
self.handId=handId
self.date=date
self.seats=seats
# does not scale, do this on small input files
with open('example_hands.txt','r') as content_file:
content = content_file.read()
chunck = re.findall(ur'^PokerStars\sHand\s#(\d+):.+?-(\s\d{4}\/\d{2}\/\d{2}\s\d{,2}:\d{2}:\d{2}).+\s+Table.+\s+^((?:Seat\s\d:\s\w+\s?\(.+\)\s*)+)',content, re.MULTILINE)
hands = []
for c in chunck:
hands.append(PockerStarHand(c[0],c[1], re.findall(ur'^Seat\s*(\d)\s*\:\s*(\w+)\s*\(([\$\u20AC])(\d+(?:\.\d+)?)',c[2].decode('utf-8') ,re.MULTILINE | re.UNICODE)))
for hand in hands:
print ("ID: " + str(hand.handId))
print ("date: " + str( hand.date))
for s in hand.seats:
print ("seat: " + str(s[0]))
print ("seat text: " + str(s[1]))
print ("seat curr: " + str(s[2].encode('utf-8')))
print ("seat price: " + str(s[3]))电流输出：
