我有一个日志文件，可能很长

2021-02-26 12:49:06.982823 API Get_balance

我想阅读该文件并仅获取搜索词的最后一行：“Get_balance”

        mysearchterm = "Get_balance"
        with open (self.__todays_log) as f:
            datafile = f.readlines()
        for line in datafile:
            if mysearchterm in line:
                print (line)
                #value = line.split()[4]
                return value

使用上面的代码，我得到了第一次出现。

我怎样才能得到最后一次出现？

因为你一拿到比赛就回来。在 for 循环结束后返回它，以便返回最后匹配的值。

with open("temp_log.out","r") as f:
for line in f.readlines():
    if "Get_balance" in line:
        result = line
print(result)
