在PySimpleGUI中使用输入键值计算遇TypeError的问题求助

问题代码 #

import PySimpleGUI as sg

def fixedDepositCalc1():
    
    layout = [
        [sg.Text("What is your principle amount?:")],
        [sg.I(key='-PRINCIPLE-')],
        [sg.Text("What is your interest rate for your deposit? Please give your answer in a percent form:")],
        [sg.I(key='-RATE-')],
        [sg.Text("What is the tenure for your fixed deposit?:")],
        [sg.I(key='-TIME-')],
        [sg.B("Ok")]
    ]

    window4 = sg.Window("Fixed Deposit Calculator - Financial Manager").Layout(layout)
    event, values = window4.read()

    if event == "Ok":
        I_MONEY = float(values('-PRINCIPLE-')) * float((values('-RATE-')/100)) * float(values('TIME'))
        P_MONEY = float(values('-PRINCPLE-')) + I_MONEY
        global principle
        principle = float(values='-PRINCIPLE-')

    
    layout2 = [
        [sg.T(f"Your principle amount is{principle}")]
    ]

    window5 = sg.Window("Fixed Deposit Calculator - Financial Manager").Layout(layout2)
    event, values = window5.read()

报错信息 #

File "c:\Users\Kashyap\Desktop\pysimplegui\fixedDepositCalc.py", line 19, in fixedDepositCalc1
    I_MONEY = float(values('-PRINCIPLE-')) * float((values('-RATE-')/100)) * float(values('TIME'))
TypeError: 'dict' object is not callable

错误原因 #

• 字典访问语法错误：values是PySimpleGUI返回的字典对象，必须用方括号[]访问键值，你多处错误使用了圆括号()（比如values('TIME')）。
• 拼写错误：values('-PRINCPLE-')里的键名少写了一个字母I，正确应为-PRINCIPLE-。
• 赋值语法错误：principle = float(values='-PRINCIPLE-')混淆了赋值符号与字典访问语法，正确写法是float(values['-PRINCIPLE-'])。
• 未处理异常分支：若用户未点击"Ok"直接关闭窗口，principle变量未定义，会导致第二个窗口创建失败。

修正后的代码 #

import PySimpleGUI as sg

def fixedDepositCalc1():
    layout = [
        [sg.Text("What is your principle amount?:")],
        [sg.Input(key='-PRINCIPLE-')],
        [sg.Text("What is your interest rate for your deposit? Please give your answer in a percent form:")],
        [sg.Input(key='-RATE-')],
        [sg.Text("What is the tenure for your fixed deposit?:")],
        [sg.Input(key='-TIME-')],
        [sg.Button("Ok")]
    ]

    window4 = sg.Window("Fixed Deposit Calculator - Financial Manager", layout)
    event, values = window4.read()
    window4.close()  # 关闭窗口释放资源

    if event == "Ok":
        try:
            # 正确访问字典值，修正拼写错误
            principle = float(values['-PRINCIPLE-'])
            rate = float(values['-RATE-']) / 100
            time = float(values['-TIME-'])
            
            interest = principle * rate * time
            total_amount = principle + interest

            # 展示完整计算结果
            layout2 = [
                [sg.Text(f"Principle amount: {principle}")],
                [sg.Text(f"Interest earned: {interest:.2f}")],
                [sg.Text(f"Total amount after tenure: {total_amount:.2f}")],
                [sg.Button("Close")]
            ]
            window5 = sg.Window("Fixed Deposit Calculator - Results", layout2)
            window5.read()
            window5.close()
        except ValueError:
            # 处理非数字输入的情况
            sg.popup_error("Please enter valid numeric values!")
    else:
        # 处理用户取消操作的情况
        sg.popup("Operation cancelled.")

fixedDepositCalc1()  # 调用执行函数

修正说明 #

1. 统一使用values[key]语法访问输入值
2. 修正键名拼写错误
3. 添加窗口关闭操作，避免资源占用
4. 增加异常处理，防止非数字输入导致崩溃
5. 补充展示利息和本息总额，完善功能
6. 调用函数确保代码可执行
