name:小李 age:18 salary:10000 car:宝马
name:小花 age:19 salary:12000 car:奔驰

 

f = open('a1',mode='r',encoding='utf-8')
lst = []
for line in f:
    dic ={}
    ll = line.split()
    for e in ll:
        ls = e.split(':')
        dic[ls[0]] = ls[1]
    lst.append(dic)
print(lst)

结果

[{'name': '小李', 'age': '18', 'salary': '10000', 'car': '宝马'}, {'name': '小花', 'age': '19', 'salary': '12000', 'car': '奔驰'}]
