>>> raw_input(">>:")>>:sean'sean'>>> raw_input(">>:")>>:12'12' 2. Python2 中有 int型(整型) 和 long型(长整型)。在区间[-24xxxxxxxxxxx,24xxxxxxxxxx] 的 整数是 int型。超过这个区间的称为 long型 python3中 无论整数有多大,都叫int型(整型)。没有long型(长整型) 3 . python2 ...
Python3 difference() 方法用于返回集合的差集，即返回的集合元素包含在第一个集合中，但不包含在第二个集合(方法的参数)中。语法 以下是 difference() 方法的语法：set.difference(set)参数 set -- 必需，用于计算差集的集合 返回值 返回一个新的集合。实例 返回一个集合，元素包含在集合 x ，但不在集合 y ：
3)copy(self, *args, **kwargs):复制一份集合,注意这是浅拷贝。4)difference(self, *args, **kwargs):差集。set1.difference(set2)等价于set1-set2,即把set1中在set2中相同的元素去掉后剩下的元素。5)isdisjoint(self, *args, **kwargs):是否空交集,若空交集则返回True,否则返回False。6)issubset(s...
If you want to use Python 3.x, but you're afraid to because of a dependency, it's probably worthwhile doing some research first. This is a work in progress and this wiki page might be outdated. Furthermore, with the large common subset supported by both Python 2.6+ and Python 3.3+, ...
set.copy()复制集合set.difference(set2)求差集,在 set 中却不在 set2 中set.intersection(set2)求交集,同时存在于 set 和 set2 中set.union(set2)求并集,所有 set 和 set2 的元素set.symmetric_difference(set2)求对称差集,不同时出现在两个集合中的元素set.isdisjoint(set2)如果两个集合没有相同的元素...
Python 3is a newer and better version ofPython 2. If you try to run thePython 2code inPython 3, then you will get the error and vice versa. In other words, the syntax ofPython 2andPython 3has significant differences. You can take them as two different programming languages, though it...

常用方法:union(), intersection(), difference(), issubset(), issuperset() 等。 fruits = {'apple','banana','cherry'}# 添加元素fruits.add('orange')print(fruits)# 输出: {'banana', 'cherry', 'apple', 'orange'}# 删除元素fruits.remove('banana')print(fruits)# 输出: {'cherry', 'apple'...
FILES AND DIRECTORIES These are subject to difference depending on local installation conventions; ${prefix} and ${exec_prefix} are installation-dependent and should be interpreted as for GNU software; they may be the same. On Debian GNU/{Hurd,Linux} the default for both is /usr. ${exec_pr...
🐛 Describe the bug I am trying to implement code on CPP, However, I found that the permute and transpose functions in cpp have different values from permute python3. Besides, the tensor after view is the same and I also try output = tens...
