How to Reverse a List in Python using While Loop You can also reverse the list using Python while looping. For example, you have a list of meeting times in your company, but due to a sudden change in the schedule, you need to reverse the meeting timings. meeting_times = ["09:00 AM...
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]...
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 ...
If you don't mind overwriting the original and don't want to use slicing (as mentioned in comments), you can call reverse() method on the list. >>> num_list = [1, 2, 3, 4, 5]>>>num_list.reverse()>>>num_list [5, 4, 3, 2, 1] If you want to loop over the reversed ...
There is no built-in function to reverse a String in Python.The fastest (and easiest?) way is to use a slice that steps backwards, -1.ExampleGet your own Python Server Reverse the string "Hello World": txt = "Hello World"[::-1]print(txt) Try it Yourself » ...
Using aforLoop Loops can also be used to reverse a string in Python - the first one we'll consider is theforloop. We can use it to iterate over the original string both ways - forwards and backward. Since we want to reverse a string, the first thing that comes to mind is to itera...

In these examples, the first loop iterates overlist1and the second loop iterates overlist2, so the resulting tuples have the form(x, y). If you were to reverse the order of the loops, the resulting tuples would have the form(y, x)instead: ...
Learn how to reverse a range in Python easily with this step-by-step guide. Discover efficient techniques and examples to master this task.
In itertools, you’ll find a function called chain() that allows you to iterate over multiple Python dictionaries one at a time. In the following sections, you’ll learn how to use these two tools for iterating over multiple dictionaries in a single loop. You’ll also learn how both tool...
