How to Efficiently Append Identical Strings to Multiple Strings in Python Using List Comprehension?

Appending Identical String to Multiple Strings in Python

You seek to modify a list of strings by appending the same additional string to each element, creating a new list with appended strings. For instance:

<code class="python">list1 = ['foo', 'fob', 'faz', 'funk']
string = 'bar'

# Append string to each list item
list2 = [...]</code>

Initially, you attempted using a combination of for loops and list comprehension to achieve this. However, a more effective approach is to utilize list comprehension, as it offers a concise and efficient way to manipulate lists.

The following solution demonstrates how to append the string 'bar' to each element of the 'list1':

<code class="python">list2 = [s + 'bar' for s in list1]</code>

Here's a breakdown of the list comprehension:

1. [s 'bar' for s in list1]: Iterates over each string 's' in 'list1' and appends the string 'bar' to it.
2. s 'bar': Concatenates the current string 's' with the string 'bar'.
3. The resulting strings form a new list, represented by 'list2'.

By employing list comprehension, you achieve the desired result of appending the string 'bar' to each element of the original list, creating a new list with the modified strings.
