字典的 dict.keys()、dict.values() 方法在python2中返回的是一个列表,python3中返回的是一个类似迭代器的"view" 对象。 python2: >>> d = {"name":"zhangsan","age":88} >>> d.keys() ['age', 'name'] >>> d.values() [88, 'zhangsan'] >>> 1. 2. 3. 4. 5. 6. python3: >>...

A better way to write this would to return the inputs from the previous function and pass them into the write() function and compute the values inside of a formatted f-string: def inches_to_meters(inches): return inches * 2.54e-2 def inches_to_centimeters(inches): return inches_to_mete...

1、Python中获取键盘值的方式：input()函数，然后打印该数据。2、也可以指定输入的类型，Python有六个标准数据类型分别是：Number（数字）、String（字符串）、List（列表）、Tuple（元组）、Set（集合）及Dictionary（字典）。3、input()获取的值Python会默认类型为str。如果直接赋值将会自动默认数据类型。
