如何添加try /除了拼寫錯誤的情況？

Question

我需要添加一個嘗試/除非用戶拼錯單詞「男」或「女」。

下面是我現在的代碼，但我的任務要求我加入try /除了拼錯「Male」或「Female」。下面的嘗試/除了我使用的代碼有助於解決用戶輸入年齡單詞的問題，而不是他們的性別拼寫錯誤。

任何幫助表示讚賞。

fem_names = [] 
fem_ages = [] 
male_names = [] 
male_ages = [] 


while True: 
    try:            
    name = raw_input('Enter name:')        
    age = raw_input('Enter age:')        
    sex = raw_input('Enter female or male:')      

    if (sex == 'female'):          
     fem_names.append(name)         
     fem_ages.append(float(age))        

    else:              
     male_names.append(name)         
     male_ages.append(float(age))        
    reply = raw_input('Type yes to continue or no to stop:')  
    if (reply == "no"):           
     break             
    except Exception: 
    print('Please enter correct information') 

tot_fem = len(fem_names)                   
tot_fem_ages = sum(fem_ages)          
if(tot_fem == 0):             
    avg_fem_age = 0.0            

else:               
    avg_fem_age = tot_fem_ages/tot_fem  




tot_male = len(male_names)          
tot_male_ages = sum(male_ages)         
if(tot_male == 0):            
    avg_male_age = 0.0            

else:               
    avg_male_age = tot_male_ages/tot_male           


print "There are", tot_fem , "total females with an average age of" , avg_fem_age, "years."    
print "There are", tot_male , "total males with an average age of" , avg_male_age, "years."

你可以通過閱讀[Python的教程]（https://docs.python.org/2/tutorial/先檢查使用 '如果'

sex = raw_input('Enter female or male:')      
if sex in ['male', 'female']: 
    if (sex == 'female'):          
     fem_names.append(name)         
     fem_ages.append(float(age))        

    else:              
     male_names.append(name)         
     male_ages.append(float(age)) 
else: 
     # raise error here 
     print "invalid sex"
