The for loop is a versatile and powerful tool used to perform repetitive tasks, iterate over sequences, and automate processes. 


A while loop in Python is a control flow statement that allows you to execute a block of code repeatedly if a given condition is true. You can nest a while loop inside a for loop in Python, allowing you to perform complex operations on multiple sequences of data at the same time. 


Here are a few examples of when using a while loop inside a for loop can be useful: 

  • Validating user input: You can use a while loop inside a for loop to repeatedly prompt the user for input and validate it until the input meets certain requirements. 
  • Processing data in chunks: You can use a for loop to iterate over a large dataset and a while loop inside the for loop to process the data in chunks. 
  • Performing multiple operations: You can use a for loop to perform one operation and a while loop inside the for loop to perform another operation. 
  • Complex combinations: You can use a for loop to iterate over a sequence of data and a while loop inside the for loop to iterate over another sequence of data or perform additional operations. 


For more information about while loop in for loop in Python, refer to the code below.

        count+=1
    print("Iteration " + str(iter) + "; count is: " + str(count))

Instructions

Follow the steps carefully to get the output easily.

  1. Install python on your IDE(Any of your favorite IDE).
  2. Copy the snippet using the 'copy' and paste it in your IDE.
  3. Run the file to generate the output.


I hope you found this useful.

I found this code snippet by searching for 'while loop nested in for loop in python' in kandi. You can try any such use case!

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. The solution is created in PyCharm 2021.3.
  2. The solution is tested on Python 3.9.7.


Using this solution, we are able to implement while loop nested in for loop in python with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to implement while loop nested in for loop in python.
