This can be done using regular expressions, which are a powerful tool for pattern matching. The following code will extract all numbers in brackets from a given string:<\/p>\n<pre><code>import re\n\n# Input string\nstring = \"This is a (1) test (2) string (3)\"\n\n# Extract all numbers in brackets\nmatches = re.findall(r\"\\(([0-9]+)\\)\", string)\n\n# Print the matches\nprint(matches)\n\n# Output: ['1', '2', '3']<\/code><\/pre>\n<p>The code above uses a regular expression to match any number of digits inside a pair of parentheses. The matches are then stored in a list, which can be used for further processing. This is a simple example of how regular expressions can be used to extract data from strings.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Introduction [ad_1] This article provides a solution to the problem of extracting all numbers in brackets with Python.
