第一步:安装PyQt5库

在终端输入:

pip install pyqt5

第二步:复制下列代码

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QHBoxLayout, QLabel, QLineEdit, QPushButton
from PyQt5.QtCore import Qt
from PyQt5.QtGui import QFont


class InputWindow(QWidget):
    def __init__(self):
        super().__init__()
        self.name_input = QLineEdit()
        self.age_input = QLineEdit()
        self.weight_input = QLineEdit()
        self.heart_rate_input = QLineEdit()
        self.respiration_rate_input = QLineEdit()
        self.init_ui()

    def init_ui(self):
        self.setWindowTitle('输入用户数据')
        self.setGeometry(100, 100, 280, 170)  # x, y, width, height
        layout = QVBoxLayout()

        # 设置整体字体
        font = QFont('Arial', 10)
        self.setFont(font)

        layout.addLayout(self.create_input("姓名:", self.name_input))
        layout.addLayout(self.create_input("年龄:", self.age_input))
        layout.addLayout(self.create_input("体重 (kg):", self.weight_input))
        layout.addLayout(self.create_input("心率 (bpm):", self.heart_rate_input))
        layout.addLayout(self.create_input("呼吸频率:", self.respiration_rate_input))

        submit_button = QPushButton("提交")
        submit_button.clicked.connect(self.submit_data)

        # 设置按钮样式
        submit_button.setFont(QFont('Arial', 10, QFont.Bold))
        submit_button.setStyleSheet("QPushButton { background-color: #4CAF50; color: white; }"
                                    "QPushButton:pressed { background-color: #66BB6A; }")

        layout.addWidget(submit_button)
        self.setLayout(layout)

        # 设置窗口样式
        self.setStyleSheet("QWidget { background-color: #EEE; }"
                           "QLabel { color: #333; }"
                           "QLineEdit { background-color: #FFF; border: 1px solid #CCC; border-radius: 5px; padding: 5px; }")

    def create_input(self, label_text, line_edit):
        layout = QHBoxLayout()
        label = QLabel(label_text)
        label.setAlignment(Qt.AlignRight | Qt.AlignVCenter)
        layout.addWidget(label)
        layout.addWidget(line_edit)
        return layout

    def submit_data(self):
        name = self.name_input.text()
        age = self.age_input.text()
        weight = self.weight_input.text()
        heart_rate = self.heart_rate_input.text()
        respiration_rate = self.respiration_rate_input.text()

        self.output_window = OutputWindow(name, age, weight, heart_rate, respiration_rate)
        self.output_window.show()

class OutputWindow(QWidget):
    def __init__(self, name, age, weight, heart_rate, respiration_rate):
        super().__init__()
        self.name = name
        self.age = age
        self.weight = weight
        self.heart_rate = heart_rate
        self.respiration_rate = respiration_rate
        self.init_ui()

    def init_ui(self):
        self.setWindowTitle('显示用户数据')
        self.setGeometry(100, 100, 320, 200)  # x, y, width, height
        layout = QVBoxLayout()

        font = QFont('Arial', 16, QFont.Bold)

        name_label = QLabel(f"姓名: {self.name}")
        age_label = QLabel(f"年龄: {self.age}")
        weight_label = QLabel(f"体重: {self.weight} kg")
        heart_rate_label = QLabel(f"心率: {self.heart_rate} bpm")
        respiration_rate_label = QLabel(f"呼吸频率: {self.respiration_rate}")

        name_label.setFont(font)
        age_label.setFont(font)
        weight_label.setFont(font)
        heart_rate_label.setFont(font)
        respiration_rate_label.setFont(font)

        layout.addWidget(name_label)
        layout.addWidget(age_label)
        layout.addWidget(weight_label)
        layout.addWidget(heart_rate_label)
        layout.addWidget(respiration_rate_label)

        self.setLayout(layout)
        self.setStyleSheet("QWidget { background-color: #FAFAFA; } QLabel { margin: 10px; }")


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

第三步:运行代码，输入信息，显示结果

运行代码后会弹出“用户数据输入”窗口：

输入数据后点击“提交”,接着会弹出“显示用户数据”界面：
