Python Split Function: Usage & Examples

In Python3, the split() function is a method used to separate a string based on a specified delimiter. The basic syntax of this function is as follows:

str.split(sep=None, maxsplit=-1)

Among them, the parameter ‘sep’ represents the delimiter, which defaults to None, indicating that white space such as a space or tab is used to split the string; the parameter ‘maxsplit’ represents the maximum number of splits, which defaults to -1, indicating splitting all substrings.

For example, let’s say we have a string like this:

str = "hello world"

If we want to divide a string using a space as a delimiter, we can use the split() method as follows:

result = str.split()
print(result)

The output is:

['hello', 'world']

In addition, we can also specify other delimiters, such as using a comma to separate strings.

str = "apple,orange,banana"
result = str.split(',')
print(result)

The output result is:

['apple', 'orange', 'banana']
