在不使用循环的情况下从文件中读取逗号分隔值？

myclass=dict()
split_list='Carlos Guestrin1,CIS 41A,4.5,A,BUS 55,5,A,BUS 18,5,B+,HUMI 16,4,A-'.split(",",maxsplit=1)
myclass[split_list[0]]=split_list[1]

print(myclass)
{'Carlos Guestrin1': 'CIS 41A,4.5,A,BUS 55,5,A,BUS 18,5,B+,HUMI 16,4,A-'}

您使用str.spltline()会返回list字符串的代码。

例如

from pprint import pprint

filename = 'test_data'
with open(filename, 'r') as inp:

data = inp.read().splitlines()

pprint(data)
样本输出：

['Carlos Guestrin1,CIS 41A,4.5,A,BUS 55,5,A,BUS 18,5,B+,HUMI 16,4,A-',
'Carlos Guestrin2,CIS 41A,4.5,A,BUS 55,5,A,BUS 18,5,B+,HUMI 16,4,A-',
'Carlos Guestrin3,CIS 41A,4.5,A,BUS 55,5,A,BUS 18,5,B+,HUMI 16,4,A-']
