这正在起作用，现在已经停止，并且给我一个错误，我看不出它是怎么回事？

以退出代码1完成的过程

如果没有满足y和y = int(y)的条件，则不会在语句if中使用您的局部变量elif之前对其进行初始化。

您可以在y子句中为else分配一个默认值：

def grade(R):
    x = str(R)
    if 'Practitioner' in x:
        y = x.replace('Practitioner', ' ')
    elif 'P' in x:
        y = x.replace('P', ' ')
    elif 'p' in x:
        y = x.replace('p', ' ')
    elif 'Graduate' in x:
        y = x.replace('Graduate', ' ')
    elif 'G' in x:
        y =x.replace('G', ' ')
    elif 'g' in x:
        y = x.replace('g', ' ')
    else:
        y = '0'

    y = int(y)
    g = inf.number_to_words(y)
    return (g)

或者您可以尝试修复输入数据，以确保参数R始终会满足if和elif子句中的条件之一。

为什么现在给我一个UnboundedLocalError？
