未定义名称“ Y”

Question

所以我一直在尝试运行以下代码：

def conference_call_discount(distance, basic_charge):
if(distance >= 50):
    con_calc = basic_charge * 0.5
    return con_calc
elif(distance < 50):
    con_calc = 0
    return con_calc

con_call = str(input("Is it a conference call? "))
from call_charge_functions import conference_call_discount
conference = conference_call_discount(dist, starting_cost)
    if con_call == y: 
         print("your conference call discount is", conference)
    else:
    conference = 0

但是我仍然收到此错误： NameError：名称“ y”未定义

我不知道怎么了

Answer 1

在这种情况下：

if con_call == y:

您没有设置y的值。

在比较之前，应为y变量设置一个值。
