TypeError：**或pow（）函数的不受支持的操作数类型：'function'和'int'概率计算器

Question

我试图将我的概率计算器放在一个漂亮的GUI中，但我遇到了一个问题，计算。

我做了3个脚本：

1. Tkinter的剧本，我的用户界面，也是地方，我让我的 人数从。
2. 我的可运行脚本，这个脚本已经到位以防止 循环导入。这也是我跑用我 “方案”
3. 我的概率计算器，它收集来自Tkinter的GUI数据的脚本， 做了计算，并再次将输出发送到Tkinter的脚本 显示结果中GUI

计算脚本，称为tennisGameProbabili ty.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manully放在值在tennisGameProbability脚本比它的工作原理。 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。我尝试了我所知道的一切，但没有任何运气。

谁能告诉我我的错误在哪里？

Answer 1

你都清楚地分配的s默认值的函数：

from run_file import projected_hold_player1 

... 

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

所以调用s**a引发的错误，因为运营商不指定函数类型的任何行为。

您应该改为将s分配给函数projected_hold_player1的返回值，前提是该值是一个数字，我认为它是。

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

或者您可以在指定默认值的同时调用该函数。

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