whereas lists are sequences of any type of Python objects. 字符串和列表之间的另一个区别是字符串是不可变的,而列表是可变的。 Another difference between strings and lists is that strings are immutable, whereas lists are mutable. 除了这两个区别之外,字符串和列表当然也有自己的方法。 In addition to...

Can you use a function to calculate the difference between two lists in Python? What is the best way to calculate the difference between two sets in Python? 在Python中计算差异值有多种方法,以下是其中一种常见的方法: 方法一:使用减法运算符 可以使用减法运算符来计算差异值。假设有两个变量a...
>>>lists.extend([1,2,3,4]) 他和+操作的区别就是, +不会改变原始的list,而extend会! (3),insert 用来往指定index后添加一个ele. >>>lists.insert(0,123)>>>lists.insert(0,[1,23]) 2,切片 使用切片,来对list直接修改. >>>lists[1:3]=[1,2,3] //只能使用另外一个list进行替代>>>lists ...
5.3 差集(Difference) **-**:从一个集合中移除另一个集合中的元素,形成新的集合。 difference_set=set1-set2print(difference_set)# 输出: {1, 2} 5.4 对称差集(Symmetric Difference) ^:找出两个集合中不共有的元素,形成新的集合。 sym_diff_set=set1^set2print(sym_diff_set)# 输出: {1, 2, 4...
