感谢一下悦姐帮忙
import re#先把文件读进来,用read读入的是字符串,readlines是list
with open('resok.txt') as f:txt = f.read()dataset = r'5low:.*|5mix:.*|5normal:.*'
para = r'MAE: (.{6})'#意思是MAE: 后面的六个东西
row_data = re.findall(dataset,txt)#正则化找到要读的内容,先找到基本的行(dataset),在找到行里的内容(para)
new_row_data = '\n'.join(row_data)#list转化为字符串
final_data = re.findall(para,new_row_data)# print(dataset)
# print('\n')
# print(new_row_data)
# print('\n')
# print(final_data)
print(len(final_data))#检查一下个数看对不对
然后画图,其实两个文档可以放在一个里面

最后贴个图:
