抱歉,我没有足够的变量信息 female .

试试这个:

def decade_total_count(decade, name):
    """
    sums up the number of births of the given 
    female baby `name` in a 10-year period
    
    Parameters:
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    decade ... starting year of the decade
    name   ... female name 
           ... str
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    """
    count = 0
    
    for i in range(decade, decade+10):
        try:
            yearly = females[(females['name']==name) & (females['year']==i)]['births'].item()
        except ValueError:
            continue
        count = count + yearly
        
    return count

如果 ValueError 被提出,只需捕捉它并运行下一个迭代。
