How do I get a substring of a string in Python?

To get a substring of a string in Python, you can use slicing. Slicing allows you to extract a substring from a string by specifying a start index and an end index.

Here's an example of how you might use slicing to get a substring of a string in Python:

s = "hello world"
substring = s[2:5]
print(substring)

This will print "llo". The start index is included in the substring, but the end index is not.

You can also leave out the start index or the end index, in which case Python will use the default values of 0 for the start index and the length of the string for the end index. For example:

s = "hello world"
substring = s[:5]
print(substring)

This will print "hello".

s = "hello world"
substring = s[2:]
print(substring)

This will print "llo world".

You can also use negative indices to start slicing from the end of the string. For example:

s = "hello world"
substring = s[-5:-2]
print(substring)

This will print "orl".
