pychram写，一个有对话框窗口 库存管理软件，可以入库和出库，查询库存，记录入库时间和出库时间，数据本地保存

好的，你可以先安装PyQt5库（如果你还没有安装的话），它可以用来创建GUI界面。然后你需要创建一个主窗口，里面包含输入和输出框、查询、入库、出库等按钮。你可以使用QTableWidget来显示库存信息，并使用SQLite作为本地数据库进行数据存储。以下是一个简单的代码示例：

import sys
import sqlite3
from PyQt5.QtCore import Qt, QDateTime
from PyQt5.QtWidgets import QApplication, QMainWindow, QWidget, QVBoxLayout, QGridLayout, QLabel, QLineEdit, QPushButton, QMessageBox, QTableWidget, QTableWidgetItem


class InventoryManager(QMainWindow):
    def __init__(self):
        super().__init__()
        self.setWindowTitle('库存管理软件')
        self.resize(800, 600)

        # 数据库初始化
        self.conn = sqlite3.connect('inventory.db')
        self.c = self.conn.cursor()
        self.c.execute('''CREATE TABLE IF NOT EXISTS inventory
                         (id INTEGER PRIMARY KEY AUTOINCREMENT,
                          name TEXT NOT NULL,
                          quantity INTEGER NOT NULL,
                          in_time TEXT NOT NULL,
                          out_time TEXT)''')
        self.conn.commit()

        # 界面初始化
        central_widget = QWidget(self)
        self.setCentralWidget(central_widget)
        vbox = QVBoxLayout(central_widget)
        grid = QGridLayout()
        vbox.addLayout(grid)

        # 标签和文本框
        grid.addWidget(QLabel('名称：'), 0, 0)
        self.name_edit = QLineEdit()
        grid.addWidget(self.name_edit, 0, 1)
        grid.addWidget(QLabel('数量：'), 1, 0)
        self.quantity_edit = QLineEdit()
        grid.addWidget(self.quantity_edit, 1, 1)

        # 查询按钮
        query_button = QPushButton('查询')
        query_button.clicked.connect(self.query_inventory)
        grid.addWidget(query_button, 2, 0)

        # 入库按钮
        in_button = QPushButton('入库')
        in_button.clicked.connect(self.in_inventory)
        grid.addWidget(in_button, 2, 1)

        # 出库按钮
        out_button = QPushButton('出库')
        out_button.clicked.connect(self.out_inventory)
        grid.addWidget(out_button, 2, 2)

        # 表格
        self.table = QTableWidget()
        self.table.setColumnCount(5)
        self.table.setHorizontalHeaderLabels(['ID', '名称', '数量', '入库时间', '出库时间'])
        vbox.addWidget(self.table)

    def query_inventory(self):
        self.table.setRowCount(0)
        name = self.name_edit.text().strip()
        self.c.execute('SELECT * FROM inventory WHERE name LIKE ?', ('%'+name+'%',))
        data = self.c.fetchall()
        for row in data:
            self.table.insertRow(0)
            for i, item in enumerate(row):
                self.table.setItem(0, i, QTableWidgetItem(str(item)))

    def in_inventory(self):
        name = self.name_edit.text().strip()
        quantity = int(self.quantity_edit.text().strip())
        in_time = QDateTime.currentDateTime().toString(Qt.ISODate)
        self.c.execute('INSERT INTO inventory (name, quantity, in_time) VALUES (?, ?, ?)', (name, quantity, in_time))
        self.conn.commit()
        QMessageBox.information(self, '提示', '入库成功！')
        self.name_edit.clear()
        self.quantity_edit.clear()

    def out_inventory(self):
        name = self.name_edit.text().strip()
        quantity = int(self.quantity_edit.text().strip())
        out_time = QDateTime.currentDateTime().toString(Qt.ISODate)
        self.c.execute('SELECT id, quantity FROM inventory WHERE name=? AND quantity>=?', (name, quantity))
        data = self.c.fetchall()
        if len(data) == 0:
            QMessageBox.warning(self, '错误', '库存不足！')
        else:
            for row in data:
                if quantity == 0:
                    break
                id, q = row
                if q >= quantity:
                    self.c.execute('UPDATE inventory SET quantity=?, out_time=? WHERE id=?', (q-quantity, out_time, id))
                    quantity = 0
                else:
                    self.c.execute('UPDATE inventory SET quantity=?, out_time=? WHERE id=?', (0, out_time, id))
                    quantity -= q
            self.conn.commit()
            QMessageBox.information(self, '提示', '出库成功！')
            self.name_edit.clear()
            self.quantity_edit.clear()

    def closeEvent(self, event):
        self.conn.close()
        event.accept()


if __name__ == '__main__':
    app = QApplication(sys.argv)
    manager = InventoryManager()
    manager.show()
    sys.exit(app.exec_())

这个程序可以创建一个主窗口，里面包含查询、入库、出库按钮和一个表格。用户可以输入名称和数量，点击对应的按钮进行操作。数据会保存在SQLite数据库中，下次打开程序时可以继续使用。
