The reversed() function in python accepts a sequence of elements and returns a reverse iterable object. Similarly, we can also reverse a tuple using the slicing syntax [::-1] in python. Here is an example: a = (1,2,3) print (a[::-1]) In the example above, we have ommited the...
18. Reverse a TupleWrite a Python program to reverse a tuple.Visual Presentation: Sample Solution:Python Code:# Create a tuple containing a single string x = ("w3resource") # Reverse the characters in the string by using the 'reversed' function, # and then convert the reversed object back...
sorted()是python的内置函数,并不是可变对象(列表、字典)的特有方法,sorted()函数需要一个参数(参数可以是列表、字典、元组、字符串),无论传递什么参数,都将返回一个以列表为容器的返回值,如果是字典将返回键的列表。 1 2 3 4 5 6 7 8 9 >>> mystring="54321" >>> mytuple=(5,4,3,2,1) >>> ...
2) By using the reversed function of Python Thereversed() functionused to reverse a list, string, etc. in Python. It acts like the above slicing property. #suppose the same input of the above program.A=[(4,5),(4,6),(6,9),(3,6),(12,0),(6,7)]B=[tuple(reversed(k))forkinA...

Slicenotation allows us to slice various collection objects such aslists, strings, tuples, and Numpy Arrays. Theslicingtrick is the simplest way to reverse a list in Python. The only drawback of using this technique is that it will create a new copy of the list, taking up additional memor...
sorted():Python内置方法。返回新的列表。 (2)list.reverse()和reversed() list.reverse()返回的是None,其作用的结果,需要通过打印被作用的列表才可以查看结果。 reversed():内置方法。经过reversed()作用之后,返回的是一个吧序列值经过倒序的迭代器,所以,需要通过遍历或list、tuple或next()方法,才能获得作用后的...
