Question

给出以下python代码：

device = {
    'BPCM' : ['Phone', 'Description: Compact', 'price', 29.99],
    'BPSH' : ['Phone', 'Description: Clam Shell', 'price', 49.99],
    'RTMS' : ['Tablet', 'Description: RoboTab - 10-inch screen and 64GB memory', 'price', 299.99],
    'RTLM' : ['Tablet', 'Description: RoboTab - 10-inch screen and 256 GB memory', 'price', 499.99],
} 

sims = {    
    "SMNO" : ['SIM card', 'Description: SIM Free (no SIM card purchased)', 'price', 0.00],
    "SMPG" : ['SIM card', 'Description: Pay As You Go (SIM card purchased)', 'price', 9.99],
}
print("Hello customer, here is your list of phone, tablet and SIM choices choices. Please choose a phone or tablet by entering your name and the item code:")  
for key, value in device.items() + sims.items():
    print("\nItem Code: " + key)
    print(" " + str(value)) 
name = raw_input("\nPlease tell me your name? ") 
print("Hello " + name)
device_choice = raw_input("Please enter item code for the phone or tablet you want?: ") 
if device_choice in device.keys():
    print("Item Code Chosen " + device_choice + str(device[device_choice]))
 if str(device[device_choice]) == 'Phone':
        print("\nSIMS available: " + str(sims[keys]))
        print("\nPlease tell me if you want SIM free or Pay As You Go by choosing its item code? ")

上面的这些行似乎有问题：

  if str(device[device_choice]) == 'Phone':
                print("\nSIMS available: " + str(sims[keys]))

是否不会像匹配“电话”字符串那样打印sims词典的键和值？任何帮助表示赞赏...

Answer 1

第str(device[device_choice])行引用了字典中的列表值。例如。

print(str(device['BPCM']))

output:
['Phone', 'Description: Compact', 'price', 29.99]

我想你想做的是

if str(device[device_choice][0]) == 'Phone':
                print("\nSIMS available: " + str(sims[keys]))

如果产品是电话，则应该通过if条件。希望这会有所帮助！

如果不打印python字典键字符串值的条件匹配
