局部变量“？” 分配前引用

Question

I am new to Python and programming in general. I would like to know how to get rid of this compile error

def health_risk(activity_level, is_smoker):
    """Counts the aliveness of a person"""  
    alive = "alive?" or "sedentary"
    very_low = "low" or "very low"
    active = "active" or "very active"    
    if (activity_level in alive) and is_smoker is True:
        xer = "extreme" 
    elif (activity_level in active) and is_smoker is True:
        xer = "medium"    
    elif (activity_level == alive) and (is_smoker is False):
        xer = "high"     
    elif (activity_level == very_low) and (is_smoker is False):
        xer = "medium"  
    elif activity_level == active and is_smoker is False:
        xer = "low"          
    return xer
level = health_risk('low', True)
print(level)

Thanks for the help and this is my first post, thanks.

Revise your variable statements to be assigned to lists.

alive = ["alive", "sedentary"]
very_low = ["low", "very low"]
active = ["active", "very active"]

Replace all == with in ,

Include the missing elif statement.

elif (activity_level in very_low) and (is_smoker is True):
    xer = "high" # or medium or whatever

note: to reduce redundancy, you could just put and is_smoker if it's True and and not is_smoker if it's False .
