 Certainly! This code provides a concise and effective way to generate a list of strings with incremental numbers using Python list comprehension. Python list comprehension is a syntactic construct that allows you to create new lists by iterating over an existing iterable and applying an expression to each item.

In the code you provided, the iterable is a range of integers from 0 to length-1. The expression applied to each item is the concatenation of the string "A" and the string representation of the item plus 1.  

The code works like this: 

  • The variable length is assigned the value 5. 
  • The variable my_name is assigned the string value "A". 
  • The list comprehension iterates over the range of integers from 0 to length-1, using the loop variable i. 
  • For each iteration, the loop variable i is incremented by one and converted to a string using the str() function. 
  • The resulting string is concatenated with the string "A" using the + operator. 
  • The concatenated string is added to the new list. 
  • The new list is assigned to the variable desired_list. 
  • After the code is executed, desired_list will contain the strings "A1", "A2", "A3", "A4", and "A5", in that order


Python list comprehension is a powerful and concise tool for creating new lists from existing tables, and it can often be used to replace longer and more complicated loops. This example allows us to create a new list with just one line of code, making it both efficient and easy to read.

  1. Copy the code using the "Copy" button above, and paste it in a Python file in your IDE
  2. Run the file to get a list with defined length in Python.

I hope you found this useful. I have added the link to dependent libraries, version information in the following sections.

I found this code snippet by searching for "how to create a list with a defined length and items in python" in kandi. You can try any such use case!

Environment Test

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

  • The solution is created in Python 3.7.15 Version

Using this solution, we can able to create a list with a defined length and items in Python. This process also facilities an easy to use, hassle free method to create a hands-on working version of code which would create a list with a defined length and items in Python.
