python文件读写编码问题

with open(src, ‘rb’) as f:
lines = f.read().decode(“utf-8”).split(’\r\n’)
使用二级制读入，然后选择编码解析

def get_aydm():
src = “C:\民事一审out\msaymc_aydm.txt”
aydm_dict = {}
with open(src, ‘rb’) as f:
lines = f.read().decode(“utf-8”).split(’\r\n’)
for line in lines:
item = line.split(" ")
aydm_dict[item[1]] = item[0]
return aydm_dict
