列表(list):表示一组有序的值,如[1, 2, 3]。 元组(tuple):类似于列表,但是一旦创建就不能再改变。 字典(dict):表示键值对的集合,如{“name”: “Alice”, “age”: 30}。 Python还有其他的数据类型,如集合(set)和字节串(bytes),这里列举的是最常用的数据类型。 在Python中可以使用type()函数来查看一...
my_tuple = (1, 2, 3) #create tuple print(my_tuple) 输出: (1,2,3) 访问元素 访问元素与访问列表中的值相同。 my_tuple2 = (1, 2, 3, 'python') #access elements for x in my_tuple2: print(x) print(my_tuple2) print(my_tuple2[0]) print(my_tuple2[:]) print(my_tuple2[3][...

Python脚本文件是两种中间文件格式中的一种。设备通过运行Python脚本来下载版本文件。 Python脚本文件的文件名必须以“.py”作为后缀名,格式如Python脚本文件示例所示。详细脚本文件解释请见Python脚本文件解释。 Python脚本文件示例 该脚本文件仅作为样例,支持SFTP协议进行文件传输,用户可以根据实际开局场景进行修改。

modf(x)The fractional and integer parts of x in a two-item tuple. Both parts have the same sign as x. The integer part is returned as a float. pow(x, y)The value of x**y. radians(x)Converts angle x from degrees to radians. ...
