Python 如何基于列表中的所有值触发运行按钮?
我有一个Tkinter应用程序,在该应用程序中我有一个Python 如何基于列表中的所有值触发运行按钮?,python,list,tkinter,button,tkinter.optionmenu,Python,List,Tkinter,Button,Tkinter.optionmenu,我有一个Tkinter应用程序,在该应用程序中我有一个选项菜单,它为我提供了列表车辆id中的所有id。请注意,此列表可以变大或变小 现在,我希望我的按钮根据用户的选择将owner和vehicleid的数据发送到数据库。因此,如果我有例如2个vehicleid的,我首先需要选择一个特定的vehicleid,对于每个vehicleid,我需要选择一个特定的所有者 因此,在2vehicleid的情况下,我的数据库应该如下所示: vehicleid owner C161 ---
选项菜单
,它为我提供了列表车辆id
中的所有id。请注意,此列表可以变大或变小
现在,我希望我的按钮根据用户的选择将owner
和vehicleid
的数据发送到数据库。因此,如果我有例如2个vehicleid的
,我首先需要选择一个特定的vehicleid
,对于每个vehicleid
,我需要选择一个特定的所有者
因此,在2vehicleid
的情况下,我的数据库应该如下所示:
vehicleid owner
C161 --- Spain
C162 --- United Kingdom
应用程序如下所示:
owner = ['Spain', 'United Kingdom', 'Malaysia']
vehicleid = ['C161', 'C162']
window = Tk()
window.title("Running Python Script") # Create window
window.geometry('550x300') # Geo of the window
##These are the option menus
dd_owner = StringVar(window)
dd_owner.set(owner[0]) # the first value
w = OptionMenu(window, dd_owner, *owner)
w.grid(row=1, column=1)
dd_id = StringVar(window)
dd_id.set(vehicleid[0])
w0 = OptionMenu(window, dd_id, *vehicleid)
w0.grid(row=0, column=1)
##The run button
run_list_button =Button(window, text="Send data of ID's to database!")
run_list_button.grid(column=0, row=3)
##These are the titles
l1 = Label(window, text='Select Owner', width=15)
l1.grid(row=1, column=0)
l0 = Label(window, text='Select vehicle id:', width = 30)
l0.grid(row=0, column=0)
mainloop()
这是我的代码:
owner = ['Spain', 'United Kingdom', 'Malaysia']
vehicleid = ['C161', 'C162']
window = Tk()
window.title("Running Python Script") # Create window
window.geometry('550x300') # Geo of the window
##These are the option menus
dd_owner = StringVar(window)
dd_owner.set(owner[0]) # the first value
w = OptionMenu(window, dd_owner, *owner)
w.grid(row=1, column=1)
dd_id = StringVar(window)
dd_id.set(vehicleid[0])
w0 = OptionMenu(window, dd_id, *vehicleid)
w0.grid(row=0, column=1)
##The run button
run_list_button =Button(window, text="Send data of ID's to database!")
run_list_button.grid(column=0, row=3)
##These are the titles
l1 = Label(window, text='Select Owner', width=15)
l1.grid(row=1, column=0)
l0 = Label(window, text='Select vehicle id:', width = 30)
l0.grid(row=0, column=0)
mainloop()
尽管你的问题令人困惑。在看过您的讨论后,我了解到您希望在用户确认其选择后才将所有数据发送到数据库
在这种情况下,您可能需要一个字典来存储车辆id和车主{“车辆id”:[],“车主”:[]}
,直到用户单击更新数据库按钮。更新数据库后,请确保清空字典,以便不再将以前选择的项插入数据库
注意:您仍然需要按下另一个按钮数次才能将数据插入字典。通过使用控制变量的跟踪方法,可以选择不使用按钮
这里有一个例子
from tkinter import *
import sqlite3
CREATE_QUERY = "CREATE TABLE IF NOT EXISTS vehicle(vehicle_id VARCHAR(5), owner VARCHAR(100));"
INSERT_QUERY = "INSERT INTO vehicle(vehicle_id, owner) VALUES(?, ?);"
SELECT_QUERY = "SELECT * FROM vehicle;"
sql_file = "sample.db"
id_dict = {"vehicle_id": [], "owner": []}
def create_data_base():
with sqlite3.connect(sql_file) as conn:
conn.execute(CREATE_QUERY)
conn.commit()
def insert_to_db():
global id_dict
with sqlite3.connect(sql_file) as conn:
for value in zip(*id_dict.values()):
conn.execute(INSERT_QUERY, value)
conn.commit()
id_dict = {"vehicle_id": [], "owner": []} # empty the list once you insert the data
display_data()
def display_data():
with sqlite3.connect(sql_file) as conn:
curr = conn.cursor()
curr.execute(SELECT_QUERY)
items = curr.fetchall()
print(items)

id_dict["owner"].append(dd_owner.get())
print(id_dict)

w0 = OptionMenu(window, dd_id, *vehicleid)
w0.grid(row=0, column=1)

上述代码将把字典中的所有数据插入数据库。首先,您应该将数据存储在某个地方(字典或文件…),然后在用户按下按钮时读取数据
import mysql.connector as mysql
....
mydb = mysql.connect(host = 'localhost',user = 'root',passwd = '****.',database = 'table_data')
data = {}
def store():
if dd_id.get() not in data:
data[dd_id.get()] = dd_owner.get()
print(data)
def upload():
cur = mydb.cursor()
for item in data.items():
sql = 'INSERT INTO table_data VALUES (%s,%s)'
params = (item[0],item[1])
cur.execute(sql,params)
mydb.commit()
print('Done')
....
# The store button
Button(window, text="Store data!",command=store).grid(column=0, row=3)
# The database button
Button(window, text="Send to database",command=upload).grid(column=0, row=4)
这将在单击相应按钮时将数据存储在数据库中,也不允许重复条目或更新条目。首先,您应该将数据存储在某个位置(字典或文件…),然后在用户按下按钮时读取数据
