3 ways to get the last characters of a string in Python
In this article, I will discuss how to get the last any number of characters from a string using Python
Using numeric index
The numeric string index in Python is zero-based i.e., the first character of the string starts with 0. If you know the length of the string, you can easily get the last character of the string
Get last character using positive index
x = 'ATGCATTTC' x[len(x)-1] 'C'
Get the last character using negative index (the last character starts at -1)
x = 'ATGCATTTC' x[-1] 'C'
Using string slices
Get the last character in a string,
x[len(x)-1:] 'C' # using negative index x[-1:] 'C'
Get the last few character in a string,
# get last 2 characters x[len(x)-2:] 'TC' # using negative index x[-2:] 'TC'
Strings can be converted to lists to access the individual characters in a string
# get last character list(x)[-1] 'C'
