一、Python基础 Python基础主要总结Python常用内置函数;Python独有的语法特性、关键词nonlocal,global等;内置数据结构包括:列表(list), 字典(dict), 集合(set), 元组(tuple) 以及相关的高级模块collections中的Counter,namedtuple,defaultdict,heapq模块。目前共有90个小例子。 1 求绝对值 绝对值或复数的模 >>>abs(-...
Here, we will create the example Python list of string values that will be used in the examples in this tutorial. So, in your Python programming IDE, run the code below to create the example Python list of strings:my_list = ["car", "radio", "wheels", "bicycle"] print(my_list) #...
Here, we will create the demo 2D Python list of integers that we will attach a new element to. Therefore, in your preferred Python IDE, run the line of code below:my_2Dlist = [[1, 2], [3, 4], [5, 6]] print(my_2Dlist) # [[1, 2], [3, 4], [5, 6]] print(type(my...

sys.getsizeof(merged2) #56 只占用56个字节,相比第一种合并方法节省内存4倍多。 一、Python之基 Python之基主要总结Python常用内置函数及用法,它们在Python中被最高频的使用,所以务必掌握。V1.0 一共包括58个。 1 求绝对值 绝对值或复数的模 In [1]: abs(-6) Out[1]: 6 2 元素都为真 接受一个迭代...
The python version 3.8 and the spyder3 IDE of python are used in this article to write the python script. You have to install spyder IDE in your system to use it. If you want to execute any script from the terminal, then run the ‘python’ or ‘python3’ command to open python in...
