In Python, replacing non-ASCII characters with a space is not a trivial task. Many solutions exist to remove non-ASCII characters, but replacement remains an uncommon requirement.
The provided function, remove_non_ascii_1, effectively removes all non-ASCII characters. remove_non_ascii_2, on the other hand, replaces non-ASCII characters with spaces, but the number of spaces corresponds to the character's code point size.
Now, let's address the central question:
How can we replace all non-ASCII characters with a single space?
Solution 1:
<code class="python">def replace_with_space(text): return ''.join([i if ord(i) < 128 else ' ' for i in text])</code>
This approach employs a conditional expression within the list comprehension of ''.join(). Characters with ASCII values under 128 remain unchanged, while non-ASCII ones are replaced with a space.
Solution 2:
<code class="python">import re def replace_with_space(text): return re.sub(r'[^\x00-\x7F]+', ' ', text)</code>
In this solution, the character in the regular expression ensures that consecutive non-ASCII characters are replaced with a single space. This eliminates the issue in remove_non_ascii_2 where multiple spaces were inserted.
