The split() method in Python is used to split a string into a list of substrings, using a specified separator. The method is called on a string, and takes a separator string as its argument.

        The general syntax of the split() method is as follows:

string.split(separator, maxsplit)

        Here, separator is the string that will be used to split the string, and maxsplit is an optional argument that specifies the maximum number of splits to be made. If maxsplit is not specified, all occurrences of the separator string are used to split the string.

        For example, the following code uses the split() method to split a string into a list of substrings, using a comma as the separator:

sentence = "Hello, world, how, are, you"
words = sentence.split(", ")
print(words)  # Output: ['Hello', 'world', 'how', 'are', 'you']

        In this example, the split() method is called on the string sentence, with the separator ", " specified as the argument.

        The split() method is useful for splitting a string into a list of substrings, for example, when you need to process a comma-separated list of values or extract individual words from a sentence.
