[英]Saving an nested list into a text file
Problem 1: I want to create a program that gathers the Name, Age and Year Group from a person. 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。 I then want to save this into a nested loop.
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)
So I tried this... 所以我尝试了这个
Name:Jack
Age:14
Year:10
[['Name', 'Age', 'Year'], ['Mark', '15', '11'], 'Jack', '14', '10']
>>>
I want the result to look like... 我希望结果看起来像...
Name:Jack
Age:14
Year:10
[['Name', 'Age', 'Year'], ['Mark', '15', '11'], ['Jack', '14', '10']]
>>>
Problem 2: I wish to then save and read from a File. 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)
It then comes up with the problem of "write()" only using strings. 然后出现仅使用字符串的“ write()”问题。 How can easily save this information so when I'm given a name I can use it to find the 2 numbers related to it?
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?
Thanks <3 谢谢<3
Problem 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)
Problem 2: 问题2:
writing 写作
with open('Details.txt','w') as f:
f.write('\n'.join([','.join(person) for person in AD]))
reading 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))
If you don't mind to save as a CSV file, then you can create a Panda data frame with 3 columns using these lists and then save as a CSV file. 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。 Later you can read the CSV file and fetch the values of "Age" and "Year" columns based on the value in "Name" column
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
