python在循环中更新字典

Updating Dictionary in a loop Python

本问题已经有最佳答案，请猛点这里访问。

我正在用python在dict数据类型中创建记录。如何使用while循环在dict中添加新项目，就像在tuples中那样，使用：

1	tuple += (rec)

当我使用此代码时，它将在tuple中添加元素，无论添加多少。如何使用dict执行相同的任务

while True:
name = input('Student Name: ')
while True:
course = input('Course Name: ')
courses.append(course)
print('You have entered', len(courses), 'course(s)')
ch_course = input('Would you like to add a new course [Y]or[N]: ')
if ch_course == 'y' or ch_course == 'Y':
continue
else:
stdrec = ({name : courses})
break
ch_name = input('Would you like to add a new record [Y]or[N]: ')
if ch_name == 'n' or ch_name == 'N':
print(stdrec)
break

要添加到名为stdrecs的dict中，需要存储一个新的键/值对，即stdrecs[name] = courses。如下所示：

stdrecs = {}
while True:
name = input('Student Name: ')
courses = []
while True:
course = input('Course Name: ')
courses.append(course)
print('You have entered', len(courses), 'course(s)')
ch_course = input('Would you like to add a new course [Y]or[N]: ')
if ch_course.upper() == 'Y':
continue
else:
stdrecs[name] = courses
break
ch_name = input('Would you like to add a new record [Y]or[N]: ')
if ch_name.upper() == 'N':
print(stdrecs)
break
