You can return a range of characters by using the slice syntax. Specify the start index and the end index, separated by a colon, to return a part of the string.

Example
Get the characters from position 2 to position 5 (not included):
b = “Hello, World!”
print(b[2:5])

Negative Indexing
Use negative indexes to start the slice from the end of the string.

Example
Get the characters from position 5 to position 1, starting the count from the end of the string:
b = “Hello, World!”
print(b[-5:-2])
