Python's reversed functionTo loop in the reverse direction, you can use Python's built-in reversed function:>>> colors = ["purple", "blue", "green", "pink", "red"] >>> for color in reversed(colors): ... print("I like", color) ... I like red I like pink I like green ...

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. To ...

Reverse string using for loop a = 'Python' b = '' for c in a: b = c + b print(b) # nohtyP Reverse the string using recursion There are many ways to reverse a string using recursion. In the presented method, the recursive function copies the last character of the string to the ...
This section will cover what I think are two of the most popular techniques for reversing a list in Python: thereverse()method and list slicing. Both methods are simple and provide unique benefits depending on your use case. These are the same two methods we looked at previously when showing...

Another approach is that - Iterate over the list usingfor ... inloop and insert each element at the 0thindex using thelist.insert()method. When a new element will be added at the 0thindex the previous element will be shifted to the next position. In this way, we will get a reverse...
