Answer 1

一つの方法は、カウントのためdefaultdictを使用することです：

from collections import defaultdict 
d = defaultdict(int) 
with open("chat.txt") as f: 
    for line in f: 
     id, data = line.split(None, 1) 
     d[id] += data.lower().count("optimus") 

Answer 2

>>> from collections import Counter 
>>> c = Counter() 
>>> for line in chat.txt: 
...  c[line.strip().split(" ",1)[0]] += line.count("Optimus") 
>>> c 
Counter({'ID67': 5, 'ID5552': 1, 'ID12120': 1, '': 0}) 

、あなたはのように値をプリントアウトすることができます：

>>> for k, v in c.items(): 
...     print("{}:{}".format(k, v)) 
...  
:0 
ID67:5 
ID5552:1 
ID12120:1
