Python Program to convert List of Integer to List of String
Given a List of Integers. The task is to convert them to List of Strings.
Examples:
Input: [1, 12, 15, 21, 131] Output: ['1', '12', '15', '21', '131'] Input: [0, 1, 11, 15, 58] Output: ['0', '1', '11', '15', '58']Method 1: Using map[]
|
# Python code to convert list of # string into sorted list of integer
# List initialization list_int = [1, 12, 15, 21, 131]
# mapping list_string = map[str, list_int]
# Printing sorted list of integers print[list[list_string]] |
Output:
['1', '12', '15', '21', '131']Example 2: Using list comprehension
|
# Python code to convert list of # string into sorted list of integer
# List initialization list_string = [1, 12, 15, 21, 131]
# Using list comprehension output = [str[x] for x in list_string]
# Printing output print[output] |
Output:
['1', '12', '15', '21', '131']Method 3: Using iteration
|
# Python code to convert list of # string into sorted list of integer
# List initialization list_string = [1, 12, 15, 21, 131]
list_int = [] # using iteration and sorted[] for i in list_string: list_int.append[i]
# printing output print[list_int] |
Output:
['1', '12', '15', '21', '131']Article Tags :

Method 1: List Comprehension
Suppose we have a list:
a = [4, 3, 2, 1, 10, 14, -14]Now, check the type of the list numbers:
print[type[a[0]]] #Let’s apply the built-in function str[], and get a list of strings using list comprehension:
print[[str[x] for x in a]] # ['4', '3', '2', '1', '10', '14', '-14']?List comprehension is a compact way of creating lists. The simple formula is [expression + context]. Expression: What to do with each list element? Context: What elements to select? The context consists of an arbitrary number of for and if statements.
You can watch me explain list comprehensions in this video:
Check the type of numbers in the new list:
A = [str[x] for x in a] print[type[A[0]]] #The built-in function str converts an integer to a string representation of that integer. Thus, it helps us create a new list of strings from the list of integers in a single line of code.

This article describes how to convert a list of strings [str] and a list of numbers [int, float] to each other in Python with sample code.
- Convert a list of numbers [int, float] to a list of strings [str]
- Convert numbers to decimal strings
- Convert numbers to binary, octal, and hexadecimal strings
- Convert numbers to exponential strings
- Convert a list of strings [str] to a list of numbers [int, float]
- Convert decimal strings to numbers
- Convert binary, octal, and hexadecimal strings to numbers
- Convert exponential strings to numbers
- Convert only strings that can be converted to numbers
List comprehension is useful to generate a new list from another list. The sample code in this article also uses the list comprehensions. See the following article for details.

4 Ways to Convert List to String in Python
While working with python data types, there are situations when you want to convert the data collected from one type to another. There are 4 methods by which we can convert a list to a string in python with fewer lines of code. These methods of converting a list into a string include iteration, comprehension, join[], and map[] method. But before understanding all these conversion methods in detail, let us understand what are lists and strings.
