Question

我正在尝试将我的概率计算器放在一个漂亮的GUI中但我遇到了概率计算的问题。

我制作了3个剧本：

Tkinter脚本，我的用户界面以及我得到的地方我的号码来自。
我的可运行脚本，此脚本已经到位以防止循环进口。这也是我运行使用my的脚本 “方案”
我的概率计算器，它从Tkinter GUI收集数据，进行计算并再次将输出发送到Tkinter脚本在GUI中显示结果

脚本

> Tkinter GUI, called testtennisGUI.py

from Tkinter import *
import ttk
import csv
import tennisGameProbability


def invullen():
    resultaat.set(str(" Game = "+("{0:.2%}".format(tennisGameProbability.game_prob()))))


def result_first_service_percentage():
    return calculate()

frame = Tk()


def calculate(*args):
    try:
        value_player1c = float(v1player1.get())/100
        value_player1d = float(v2player1.get())/100
        value_player1e = float(v3player1.get())/100
        result_player_1.set(str("{0:.3}".format((((value_player1c * value_player1d)-(value_player1c * value_player1e)) + value_player1e)*100)))
        return ((value_player1c * value_player1d)-(value_player1c * value_player1e)) + value_player1e

run = ttk.Button(frame, text='Run', command=invullen)
run.grid(column=1, row=7, columnspan=2, ipadx=15, pady=25)
mainloop()

我运行的脚本，名为run_file.py

import testtennisGUI


def projected_hold_player1():
    return testtennisGUI.result_first_service_percentage()

计算脚本，名为tennisGameProbability.py

from run_file import projected_hold_player1


def fact(x):
    if x in [0, 1]:
        return 1
    r = 1
    for a in range(1, (x + 1)):
        r = r * a
    return r


def ch(a, b):
    return fact(a) / (fact(b) * fact(a - b))
    pass


def game_outcome(s, a, b):
    return ch((a + b), a) * (s ** a) * ((1 - s) ** b) * s


def game_prob(s=projected_hold_player1, v=0, w=0):
    if v >= 4 and (v - w) >= 2:
        return 1
    elif w >= 4 and (w - v) >= 2:
        return 0
    else:
        pass
    while True:
        if (v + w) > 6:
            v -= 1
            w -= 1
        else:
            break
    if w == 0:
        w0 = game_outcome(s, 3 - v, 0)
    else:
        w0 = 0
    if w <= 1:
        w15 = game_outcome(s, 3 - v, 1 - w)
    else:
        w15 = 0
    if w <= 2:
        w30 = game_outcome(s, 3 - v, 2 - w)
    else:
        w30 = 0
    if v == 4:
        wad, lad = s, 0
        d = 1 - s
    elif w == 4:
        wad, lad = 0, 1 - s
        d = s
    else:
        wad, lad = 0, 0
        a = 3 - v
        b = 3 - w
        d = ch((a + b), a) * (s ** a) * ((1 - s) ** b)
    if v <= 2:
        l30 = game_outcome((1 - s), 3 - w, 2 - v)
    else:
        l30 = 0
    if v <= 1:
        l15 = game_outcome((1 - s), 3 - w, 1 - v)
    else:
        l15 = 0
    if v == 0:
        l0 = game_outcome((1 - s), 3 - w, 0)
    else:
        l0 = 0
    denom = s ** 2 + (1 - s) ** 2
    wd = (d * (s ** 2)) / denom
    ld = (d * ((1 - s) ** 2)) / denom
    win = w0 + w15 + w30 + wd + wad
    lose = l0 + l15 + l30 + ld + lad
    return win
    return game_prob()

我得到的错误是：

File "C:\Users\Magali\PycharmProjects\Wouter\tennisGameProbability.py", line 19, in game_outcome
    return ch((a + b), a) * (s ** a) * ((1 - s) ** b) * s
TypeError: unsupported operand type(s) for ** or pow(): 'function' and 'int'

当我在tennisGameProbability脚本中输入值而不是它的作用时。所以我认为问题在于我的变量数据在脚本之间移动的方式。我已经尝试了所有我知道但没有运气的事情。

谁能告诉我我的错误在哪里？

Answer 1

您显然将s的默认值指定为函数：

from run_file import projected_hold_player1

...

def game_prob(s=projected_hold_player1, v=0, w=0)
#             ^^^^^^^^^^^^^^^^^^^^^^^^

因此，调用s**a会引发该错误，因为运算符没有为函数类型指定任何行为。

您应该将s分配给函数projected_hold_player1的返回值，前提是该值是一个数字，我认为是。

def game_prob(s=None, v=0, w=0):
    if s is None:
         s = projected_hold_player1()

或者您可以在分配默认值时调用该函数。

def game_prob(s=projected_hold_player1(), v=0, w=0)
#                                     ^^

TypeError：**或pow（）不支持的操作数类型：'function'和'int'概率计算器
