将嵌套列表保存到文本文件中

Question

问题1：我想创建一个程序来收集一个人的姓名，年龄和年份。 然后，我想将其保存到嵌套循环中。

AD = [["Name","Age","Year"],["Mark","15","11"]]

Inp = input("Name:")
AD.append(Inp)

Inp = input("Age:")
AD.append(Inp)

Inp = input("Year:") 
AD.append(Inp)

print(AD)

所以我尝试了这个

Name:Jack
Age:14
Year:10
[['Name', 'Age', 'Year'], ['Mark', '15', '11'], 'Jack', '14', '10']
>>> 

我希望结果看起来像...

Name:Jack
Age:14
Year:10
[['Name', 'Age', 'Year'], ['Mark', '15', '11'], ['Jack', '14', '10']]
>>> 

问题2：我希望然后保存并从文件中读取。

AD = [["Name","Age","Year"],["Mark","15","11"]]

Inp = input("Name:")
AD.append(Inp)

Inp = input("Age:")
AD.append(Inp)

Inp = input("Year:")
AD.append(Inp)

File = open("Details.txt","w")
File.write(AD)
File.close()

print(AD)

然后出现仅使用字符串的“ write（）”问题。 如何轻松保存此信息，以便在获得名称后可以使用它来查找与之相关的2个数字？

谢谢<3

Answer 1

问题一：

AD = [["Name","Age","Year"],["Mark","15","11"]]

name = input("Name:")
age = input("Age:")
year = input("Year:") 

AD.append([name, age, year])
print(AD)

问题2：

写作

with open('Details.txt','w') as f:
    f.write('\n'.join([','.join(person) for person in AD]))

读

with open('Details.txt', 'r') as f:
   lines = f.readlines()
   AD = {}
   for line in list(lines)[1:]:
       name, age, year = line.split(',')
       AD[name] = [age, year]

name = input('Wich person do you want to squery? ')
age, year = AD[name]
print('This person has age {0} and year {1}'.format(age, year))

如果您不介意另存为CSV文件，则可以使用这些列表创建具有3列的Panda数据框，然后另存为CSV文件。 稍后，您可以读取CSV文件并根据“名称”列中的值获取“年龄”和“年份”列中的值
