我正在尝试在匹配时更新子字符串的值。出于某种原因，我最终无法理解所有子字母都具有相同的值。
def (d,content):
for i in d:
for x in d[i]:
regex = re.compile(i + '.*.' + x + '.*')
for string in content:
if (bool(regex.match(string))) == True:
d[i][x] +=1
print("match")
我刚开始学习Python。我无法理解问题Update value of a nested dictionary of varying depth的答案中的逻辑。
下面是输入字典的样子。

以下是我创建字典的方式。
uniq_time = sorted(set([" ".join([" ".join([x[0],x[1]]),x[2][:-1]]) for x in mlist]), key=str.lower)
uniq_processes = sorted(set([ x[4].split('[')[0] for x in mlist]), key=str.lower)
d = dict.fromkeys(uniq_time, dict.fromkeys(uniq_processes, 0))
