[已解决]python入门级 遍历字典出现的问题

上官羽锦

<div class="blockcode"><blockquote>number = {} #先定义一个空字典
number['alan']='1'#alan喜欢的数字是1
number['amy']='2'#amy喜欢的数字是2
number['jack']='3'#jack喜欢的数字是3
print("alan's favorite number is "+number['alan'])#打印输出alan喜欢的数字
print("amyy's favorite number is "+number['amy'])#打印输出amy喜欢的数字)
print("jack's favorite number is "+number['jack'])#打印输出jack喜欢的数字
for name in number.keys:#使用for循环遍历字典
    print(name)
print(number)#打印字典

大神帮我看看为什么出错了...

keys 是一个方法，需要加括号调用

keys后面要有小括号吧
