当DiceRoll＆＃39;和＆＃39; RollDiff＆＃39;功能运行＆＃39; name1＆＃39;和＆＃39; name2＆＃39;没有打印，即使它们被退回。还有＆＃39; name1 / 2modstr / ski＆＃39;也没有打印，即使计算完成，它们都返回0.没有IDLE错误，所以据我所知这是一个我未能看到的逻辑错误。

Answer 1

将打印功能更改为此类

print("{} rolled {}".format(name1, roll1))

Answer 2

Start()函数中的所有变量都是该函数的本地变量。当你return时，你可以获得这些变量的值，但前提是你在另一个函数的arg中返回它们。

本地范围示例：

>>> bar = 'rab'   #set var bar to 'rab'
>>> def foo(bar): #function that returns
    bar = 'bar'   #var bar as string 'bar'
    return bar
>>> foo(bar)      #call foo() function
'bar'             #returns the value of bar inside the scope of foo()
>>> bar           #ask for the bar var made earlier
'rab'             #still set to 'rab'

你想要什么，将函数作为参数调用（返回值出现！）：

>>> def foo2(arg): #this is like your DiceRoll function
    print(arg)     
>>> foo2(foo(bar)) #when you call it and pass foo(bar) as an arg
bar                #it prints the return of foo(bar)

编辑：它在DiceRoll中无效的原因是因为您在调用DiceRoll并分配该变量的函数中留下了对该变量的引用＆＃ 39; s对第一个创建的实例的值（即''或0，在这种情况下）。考虑这个示例并将逻辑应用于您的代码。

a = 'a'
b = 0

def start():
    a = 'string'
    b = 1
    nextFunc(a, b)

def nextFunc(a, b):
    print(a, b)      #a,b exist as 'string' and 1 is this func,
    c = 0            #but when you call lastFunc,  
    d = 1            #and don't pass a,b, they will
    lastFunc(c, d)   #show up in lastFunc as 'a' and 0

def lastFunc(c, d):
    print(a, b, c, d)

start()

在计算和返回后，不会打印变量
