a = {'Mac Grady':1,'YaoMing':11,'Wade':3,'James':23,'Kobe':24} print('球员的号码如下：') for x in a: print(x) name = input('请输入球员的名称查询球衣号码：') sign = a.get(name,False) if sign == False: print('没有该球员，请重新输入\n') else: number = int(a[name]) print(name,'的球衣号码是',number)

变量number的定义貌似有点多余，直接用 sign 也是可以的 else: print(name,'的球衣号码是',sign)

加个sign太麻烦了。。。直接 if name in a: print('没有该球员，请重新输入\n') else: number = int(a[name]) print(name,'的球衣号码是',number) 就可以了吧 。
