1、其实python3是range()和python2是xrnage(),有区别的 2、应该是技术进步,但是在这个模块不一定,可能叫“惰性技术”。 3、占内存检测 1 2 3 4 5 6 7 importsys r=range(1,10000) size_r=sys.getsizeof(r) print(f"The range() function uses {size_r} bytes of memory.") 用python2解释器不了...
What is the range() Function in Python? The range() function returns a sequence of numbers and is immutable, meaning its value is fixed. The range() function takes one or at most three arguments, namely the start and a stop value along with a step size. range() was introduced in Pyth...
Python range() Function The Pythonrange()function generates a sequence of numbers. By default, the sequence starts at 0, increments by 1, and stops before the specified number. Example # create a sequence from 0 to 3numbers = range(4)# iterating through the sequenceforiinnumbers:print(i)...
在默认情况下,Python的range函数生成的数字序列是左闭右开区间。也就是说,生成的序列包含起始值,但不包含终止值。 例如,range(5)生成的序列是0、1、2、3、4,不包含5。 然而,我们可以通过一些技巧来实现闭区间的效果。 下面是一张示意图,展示了range函数闭区间的实现流程: ...
