如何使用Python 3将信息存储在MySQL中？

Question

我想用python存储简单的信息，比如mysql表中的数字。 我将MySQL本地服务器链接到PyCharm，但我不知道如何编写代码来将信息存储在表中。 我在考虑使用一些简单的“if's”并将打印的结果即时存储在某个表中

我该怎么做

谢谢！ 首先，如果我能只存储价格，那就太好了。 我的代码：

    running = True

while running:
    try:
        buget = int(input("Money: "))
    except ValueError:
        print("Please enter your buget using only numbers!")
        continue
    else:
        print("Continue to the next step.")
        break

class Cars:
    def __init__(self,model,consumption,price,transmision):
        self.model = model
        self.consumption = consumption
        self.price = price
        self.transmision = transmision
        self.combination = model + " " + price

car_1 = Cars("BMW", "7%", "20000", ["Manual"])
car_2 = Cars("Audi", "8%", "30000 euro", ["Automated"])
car = (car_1, car_2)

for masini in car:
    guess = str(input("What car would you like? ").capitalize())
    if guess == "Bmw" and buget >= 20000:
        print("-----------------")
        print(car_1.model)
        print(car_1.consumption)
        print(car_1.price)
        print(",".join(car_1.transmision))
        print(car_1.combination)
    elif guess == "Audi" and buget >= 30000:
        print("-----------------")
        print(car_2.model)
        print(car_2.consumption)
        print(car_2.price)
        print(",".join(car_2.transmision))
        print(car_2.combination)
    elif guess == "Bmw" and buget < 20000:
        print("You can't afford this car.")
    elif guess == "Audi" and buget < 30000:
        print("You can't afford this car.")
    elif guess is not "Audi" and buget < 30000:
        print("This car doesn't exist!")
    elif guess is not "Bmw" and buget < 20000:
        print("This car doesn't exist.")
    else:
        print("This car is unavailable!")
    break

首先，你需要一个驱动程序来处理你的连接。一个被广泛使用的是：MySQLdb您可以用pip或手动安装它：

pip install MySQL-python

拥有模块后，可以通过以下方式连接到db：

db = MySQLdb.connect("localhost","testuser","test123","TESTDB" )

请确保已使用import MySQLdb导入脚本顶部的模块。之后，就可以开始使用数据库了。请参阅非常好的教程here
