The reversed string(using loops) is : skeegrofskeeG Explanation :In above code, we call a function to reverse a string, which iterates to every element and intelligentlyjoin each character in the beginningso as to obtain the reversed string. Using recursion # Python code to reverse a string...
def reverse_enum(L): for index in reversed(xrange(len(L))): yield index, L[index] L = ['foo', 'bar', 'bas'] for index, item in reverse_enum(L): print index, item #3 L = ['foo', 'bar', 'bas'] for index in reversed(range(len(L))): print index, L[index]...

Traverse a Python list in reverse order: In this tutorial, we will learn how to iterate/traverse a given Python list in reverse order using multiple approaches and examples.
You can also take advantage ofsorted()to iterate through a string in sorted and reversed order: Python >>>forvowelinsorted(vowels,reverse=True):...print(vowel)...uoiea Thereverseargument tosorted()allows you to sort iterables, including strings, in descending order. So, if you ever need ...
Python __reversed__ method The__reversed__magic method implementation should return a new iterator object that iterates over all the objects in the container in reverse order. reversed_magic.py #!/usr/bin/python class Vowels: def __init__(self): ...
Using Python for loop, you can iterate over characters in a string and append a character to the beginning of a new string. This will reverse the provided string. Reverse string using for loop a = 'Python' b = '' for c in a: b = c + b print(b) # nohtyP Reverse the string ...
In this method, we will use reversed() method and iterate over the reversed iterator to get the reversed string. Python program to reverse a string using stack and reversed() method importsysdefpush(element,size,stack):'''this function is used to push the elementsin the stack and it will...
1.2 Reverse an Array using the For Loop in Python You can use afor looptoiterate the given arrayin reversing order. In general, therange()function can generate the sequence of numbers, if you set the step param with a negative value, it can generate a sequence of decreasing numbers. ...
Let’s understand the code part,for num in numbers:aforloop is used to iterate over each element innumbers. Then new list is created by concatenating the current element with thereverse_numusing the+operator. Specifically, the current element is added to the front ofreverse_numby placing it ...
