How to Append Strings to a List of Strings in Python?

Concatenating Strings to a List of Strings in Python

Problem:

You desire to append a specific string to each element of a given string list, resulting in a new list with these augmented strings.

Example:

Consider the following initial state:

list1 = ['foo', 'fob', 'faz', 'funk']
string = 'bar'

After the desired operation, the expected output would be:

list2 = ['foobar', 'fobbar', 'fazbar', 'funkbar']

Solution:

The most straightforward approach to accomplish this is to utilize a list comprehension:

<code class="python">[s + string for s in list1]</code>

In this comprehension:

• s represents each string in list1.
• concatenates s with the specified string.

If the efficiency of memory usage is a concern, consider using a generator expression instead, as it provides an iterator rather than a list:

<code class="python">(s + string for s in list1)</code>
