为什么遍历列表的运行结果会出现四次呢？

Question

您好，在做python基础教程中 ‘历嵌套有字典的列表’练习 时遇到了一个问题：
我希望通过两个for遍历列表，但是为什么运行结果会重复四次呢？

原代码：
alanlaye = {'f_n':'alan','l_n':'laye','age':19,'city':'tokyo'}
izakkull = {'f_n':'izakku','l_n':'ll','age':17,'city':'beijing'}
alexhers = {'f_n':'alex','l_n':'hers','age':21,'city':'marchtown'}
people = [alanlaye,izakkull,alexhers]
for peo in people:
for k,v in peo.items():
print('Full name = '+peo['f_n']+person['l_n'])
print('Age = '+str(peo['age']))
print('City = '+peo['city'])

运行结果及报错内容：
Full name = alanlaye
Age = 19
City = tokyo
Full name = alanlaye
Age = 19
City = tokyo
Full name = alanlaye
Age = 19
City = tokyo
Full name = alanlaye
Age = 19
City = tokyo
Full name = izakkull
Age = 17
City = beijing
Full name = izakkull
Age = 17
City = beijing
Full name = izakkull
Age = 17
City = beijing
Full name = izakkull
Age = 17
City = beijing
Full name = alexhers
Age = 21
City = marchtown
Full name = alexhers
Age = 21
City = marchtown
Full name = alexhers
Age = 21
City = marchtown
Full name = alexhers
Age = 21
City = marchtown

我想要达到的结果：
每一项只出现一次就够了

Answer 1

for k,v in peo.items():
print('Full name = '+peo['f_n']+person['l_n'])
print('Age = '+str(peo['age']))
print('City = '+peo['city'])
已经使用了 for k,v in peo.items()，为什么后面还要使用peo去调取字典？这样的话k和v完全没有用到，循环的次数等于字典的键值个数
