How do I get a substring of a string in Python?
To get a substring of a string in Python, you can use the string slicing notation, which is string[start:end]
, where start
is the index of the first character of the substring, and end
is the index of the character just after the last character of the substring. For example:
string = "Hello, world!"
substring = string[7:12]
print(substring)
This would output "world"
.
If you omit the start
index, the substring will start from the beginning of the string. If you omit the end
index, the substring will continue to the end of the string.
You can also use negative indices to specify the start
and end
indices relative to the end of the string, with -1
being the last character, -2
being the second-to-last character, and so on.
For example:
string = "Hello, world!"
substring = string[-5:]
print(substring)
This would also output "world"
