How to Append Same String to a List Using List Comprehension in Python?

Concatenating Strings to a List in Python

In Python, it is common to encounter scenarios where you need to append the same string to a list of strings and create a new list with the modified strings. To achieve this, list comprehension is a powerful tool that can simplify the process.

Solution Using List Comprehension:

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

# Append mystring to each element in mylist using list comprehension
modified_list = [s + mystring for s in mylist]</code>

In the above code, the list comprehension iterates over the elements of mylist and concatenates each element with mystring. The modified list is stored in modified_list, which will contain the following values:

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

Additional Tips:

• When using list comprehension, it's recommended to avoid using built-in names like list as it can lead to naming conflicts.
• If you don't need to create a new list, but only require an iterator, consider using a generator expression instead.
• List comprehensions and generator expressions are powerful and concise tools that can significantly enhance your Python programming abilities.
