python match regular expression in string

To use regular expressions in Python, you need to import the re module. Open your Python environment or script and include the following:
In this example, the pattern is "Hello," and the string is "Hello, World!". The output will be "Match found: Hello" because the pattern is found at the beginning of the string.
By using the re.IGNORECASE flag, the pattern will match regardless of case. The output will be "Match found: Hello."
Regular expressions support a variety of special characters and patterns for more complex matching. Here are a few examples:
In this example, the pattern "^\d+" matches one or more digits at the beginning of the string.
This pattern matches a simple email address format.
