Answer 2

The fix to the regular expression in the rearrange_name function is:

result = re.search(r"^([\w \.-]), ([\w \.-])$", name)

In programming, regular expressions are defined patterns used in string variables and values to match the required output.

From the complete program, the first line imports the regular expression module as re.

So, we make use of the module name "re" to control the regular expression.

The regular expression that gives the required string format is:

result = re.search(r"^([\w \.-]), ([\w \.-])$", name)

Where:

• [\w \.-] is used to match the names
• re is the variable name used for the regular expression
