我正在尝试使用while循环将对象添加到列表中。
这基本上就是我想做的事情:
class x:
pass
choice = raw_input(pick what you want to do)
while(choice!=0):
if(choice==1):
Enter in info for the class:
append object to list (A)
if(choice==2):
print out length of list(A)
if(choice==0):
break
((((other options))))
我可以将对象添加到列表中,但我仍然坚持如何在循环中向列表中添加多个对象。
这是我到目前为止的代码:
print "Welcome to the Student Management Program"
class Student:
def __init__ (self, name, age, gender, favclass):
self.name = name
self.age = age
self.gender = gender
self.fac = favclass
choice = int(raw_input("Make a Choice: " ))
while (choice !=0):
if (choice==1):
print("STUDENT")
namer = raw_input("Enter Name: ")
ager = raw_input("Enter Age: ")
sexer = raw_input("Enter Sex: ")
faver = raw_input("Enter Fav: ")
elif(choice==2):
print "TESTING LINE"
elif(choice==3):
print(len(a))
guess=int(raw_input("Make a Choice: "))
s = Student(namer, ager, sexer, faver)
a =[];
a.append(s)
raw_input("Press enter to exit")
非常感谢任何帮助!

问题似乎是您在每次迭代中将列表重新初始化为空列表:
while choice != 0:
...
a = []
a.append(s)
尝试在循环上方移动初始化,使其仅执行一次。
a = []
while choice != 0:
...
a.append(s)

循环中自动递增索引:
myArr[(len(myArr)+1)]={"key":"val"}
