Section 3.12 Some Extra String Methods (Optional)
In addition to what we have seen in the previous section, the following table provides a summary of some other string methods. You don’t have to memorize them.
| Method | Parameters | Description |
|---|---|---|
| capitalize | none | Returns a string with first character capitalized, the rest lower |
| strip | none | Returns a string with the leading and trailing whitespace removed |
| lstrip | none | Returns a string with the leading whitespace removed |
| rstrip | none | Returns a string with the trailing whitespace removed |
| center | width | Returns a string centered in a field of width spaces |
| ljust | width | Returns a string left justified in a field of width spaces |
| rjust | width | Returns a string right justified in a field of width spaces |
| rfind | item | Returns the rightmost index where the substring item is found, or -1 if not found |
| find | item | Like index except returns -1 if item is not found |
| rindex | item | Like rfind except causes a runtime error if item is not found |
You should experiment with these methods so that you understand what they do. Note once again that the methods that return strings do not change the original. You can also consult the Python documentation for strings 1 .
