It’s not an accident that strings and lists behave so similarly. They are both special cases of a more general object type called an iterable, which you will encounter in more detail in the upcoming tutorial on definite iteration.By the way, in each example above, the list is always ...
>>> ls3=[1,1.0,print(1),True,['list',1],(1,2),{1,4},{'one':1}] 1 >>> ls3.clear() >>> print(ls3) [] 五、 查 1、区间访问和索引访问,自不必多言。 2、max()/min(); 3、元素出现次数ls.count(x)、长度len(ls); 4、查找指定值在列表出现的第一个位置:ls.index(x):返回...
In this scenario, we start with a list of our favorite colors which is represented by “favorite_colors”. Then, we have some new colors that we’d like to include in the “additional_colors” list. Using the “+= operator”, we combine the new colors with our existing favorites, modif...
