6.3. Strings and Operators

6.3.1. Standard Type Operators

In Chapter 4, we introduced a number of operators that apply to most objects, including the standard types. We will take a look at how some of those apply to strings. For a brief introduction, here are a few examples using strings:

>>> str1 = 'abc'
>>> str2 = 'lmn'
>>> str3 = 'xyz'
>>> str1 < str2
1
>>> str2 != str3
1
>>> (str1 < str3) and (str2 == 'xyz')
0

When using the value comparison operators, strings are compared lexicographically (ASCII value order).

6.3.2. Sequence Operators

Slices ([ ] and [ : ])

Earlier in Section 6.1.1, we examined how we can access individual or a group of elements from a sequence. We will apply that knowledge to strings in this section. In particular, ...
