Python GUIグラフィックス計算機

Question

私はグラフィックライブラリから店の電卓を作ろうとしていますが、私のプログラムは未知の理由によりクラッシュしています。私が計算ボタンをクリックするたびに、それは実行を停止し、出力は得られません。ここで私は今のところ持っているものです。

# graphical interface. 
from graphics import * 
def main(): 
win = GraphWin("Celsius Converter", 600, 500) 
win.setCoords(0.0, 0.0, 3.0, 4.0) 

# Draw the interface 
Text(Point(1,3.9), " Enter name:").draw(win) 
Text(Point(1,3.7), " Crunchy tacos at $1.99 each:").draw(win) 
Text(Point(1,3.5), " Soft tacos at $2.09 each:").draw(win) 
Text(Point(1,3.3), " Bean burritos at $2.49 each:").draw(win) 
Text(Point(1,3.1), " Chicken burritos at $2.99 each:").draw(win) 
Text(Point(1,2.9), " Taco salads at $3.49 each:").draw(win) 
Text(Point(1,2.7), " Extra salsa at $.30 each:").draw(win) 
Text(Point(1,1), "Due:").draw(win) 
input1 = Entry(Point(2,3.9), 5) 
input1.setText("Name") 
input1.draw(win) 
input2 = Entry(Point(2,3.7), 5) 
input2.setText("0") 
input2.draw(win) 
input3 = Entry(Point(2,3.5), 5) 
input3.setText("0") 
input3.draw(win) 
input4 = Entry(Point(2,3.3), 5) 
input4.setText("0") 
input4.draw(win) 
input5 = Entry(Point(2,3.1), 5) 
input5.setText("0") 
input5.draw(win) 
input6 = Entry(Point(2,2.9), 5) 
input6.setText("0") 
input6.draw(win) 
input7 = Entry(Point(2,2.7), 5) 
input7.setText("0") 
input7.draw(win) 
output = Text(Point(2,1),"") 
output.draw(win) 
button = Text(Point(1.5,2.0),"Calculate") 
button.draw(win) 
Rectangle(Point(1,1.5), Point(2,2.5)).draw(win) 
# wait for a mouse click 
win.getMouse() 

# convert input 
name = input1.getText() 
crunchy = float(input2.getText()) * 1.99 
soft = float(input3.getText()) * 2.09 
bean = float(input4.getText()) * 2.49 
chicken = float(input5.getText()) * 2.99 
salad = float(input6.getText()) * 3.49 
salsa = float(input7.getText()) * 0.30 
costBefore = (crunchy + soft + bean + chicken + salad + salsa) 
tax = 0.075 * costBefore 
cost = costBefore + tax 

# display output and change button 
output.setText("Hello", name, ",your total is: ", cost) 
button.setText("Quit") 

# wait for click and then quit 
win.getMouse() 
win.close() 

main() 

Answer 1

setText()することは、一つの引数

output.setText("Hello {}, your total is: {}".format(name, cost))
