Python字典酸洗

Question

这是我的代码，但不能用pickle加载它后，也认为这是相当低效，谢谢。 写入文件：

import pickle 

cont="yes" 
u_ele_stu={} 
ele_pl_stu={} 
x=len(u_ele_stu) 
y=len(ele_pl_stu) 

with open("Tennis Scores.txt" ,"wb") as a: 
while cont=="yes": 
    age=input("Would you like to add to under 11 list or 11-16? (under 11/11-16)") 
    if age=="under 11": 
     name=input("Input the name of a student: ") 
     pos=str(input("Input the last position they achieved in a tournament")) 
     u_ele_stu[x+1]=name, " ", pos 
    elif age=="11-16": 
     name=input("Input the name of a student: ") 
     pos=str(input("Input the last position they achieved in a tournament")) 
     ele_pl_stu[y+1]=name, " ", pos 
    cont=input("Would you like to add another student? yes/no") 
    cont.lower() 
if cont!="yes": 
    pickle.dump(u_ele_stu, a) 
    pickle.dump(ele_pl_stu, a) 

读取文件：

import pickle 

with open("Tennis Scores.txt", "r") as a: 
    b=pickle.load(a) 
    c=pickle.load(a) 
    print(b) 
    print(c) 

Answer 1

尝试在一个单独的文件倾倒每个对象：

with open('u_ele_stu.txt', 'wb') as f: 
    pickle.dump(u_ele_stu, f) 

with open('ele_pl_stu.txt', 'wb') as f: 
    pickle.dump(ele_pl_stu, f) 

Answer 2

我通过添加B固定的问题在“r “，我不认为这是最有效的方式，但它只是比较...

与开放（ “网球Scores.txt”， “R b”）为：
