2) Using while Loop Example: # Program to explain reverse string# Using while loop# Define a functiondefreverse_while(string):# Declare a string variablerstring =''# We will calculate string length# And subtract 1 because string index start with 0length =len(string) -1# We will run the...
Python Code: # Define a function named 'string_reverse' that takes a string 'str1' as inputdefstring_reverse(str1):# Initialize an empty string 'rstr1' to store the reversed stringrstr1=''# Calculate the length of the input string 'str1'index=len(str1)# Execute a while loop until...
whileidx>=0:newList.append(numbers[idx])idx=idx-1print(newList) Output: [52, 44, 105, 34, 17, 97, 45, 2, 78, 66] Reverse a List Using the Slice Operator in Python If you prefer not to loop over the list, then use thesliceoperatorto decrement the array index by 1. ...
Here,reversed_numbersis a new list containing the elements ofnumbersin reverse order, whilenumbersremains unchanged. Choosing the right technique In summary, usereverse()for in-place modifications when you don’t need the original list in its initial order.Use slicing ([::-1]) when you want ...
2. Using reversed() method You can also usereversed()method while iterating over the list elements. It returns a reverse iterator and it does not modify the given list. Example # Traverse a Python list in reverse order# Using reversed() method# Define a listlist1=[10,20,30,40,50]# ...
= 0 is false. It will skip the statement defined inside the while loop. Let’s see how to find a reverse number in C++ using the While loop. Code: #include <iostream> using namespace std; int main() { int number, reverse_number = 0;...
In this short guide, learn how to reverse a string in Python, with practical code examples and best practices - using the slice notation with a negative step, a for loop, a while loop, join() and reversed().
