Question

例如，何时：

name = input('Please enter your name:\n')

并输入：William

关闭python shell后，变量“name”消失了。我如何保存这些信息，以便下次可以使用它？

读取和写入文件：Python 3.5 documentation

filename = 'names.txt'
name = str(input('Give me your name, now!\nName: '))
with open(filename, 'w') as f: f.write(name)
with open(filename, 'r') as f: original_name = str(f.read()).strip()

在SQLite3数据库中存储信息：Python 3.5 Documentation

import sqlite3
name = str(input('Give me your name, now!\nName: '))
with sqlite3.connect('names.db') as conn:
    cur = conn.cursor()
    cur.execute(
        'CREATE TABLE IF NOT EXIST Name (person_name TEXT);'
        'INSERT INTO Name VALUES ({});'.format(name)
    )
    conn.commit()

    original_name = cur.execute(
        'SELECT * FROM Name'
    ).fetchall()[0]

将实际Python对象存储/序列化为文件（能够重新加载它们）：Python 3.5 Documentation

import pickle
name = str(input('Give me your name, now!\nName: '))
with open('names.pkl', 'wb') as f:
    pickle.dump(name, f)
with open('names.pkl', 'rb') as f:
    original_name = pickle.load(f)
