How Does Python\'s .title() Method Handle Apostrophes in Strings?

Capitalizing the First Letter of Each Word String

Strings are essential in programming, and often require manipulation and formatting. A common task is capitalizing the first letter of each word in a string.

Consider the string s = 'the brown fox'. To convert this string to 'The Brown Fox', the .title() method provides a convenient solution. This method returns a new string with the first letter of each word capitalized, as demonstrated below:

<code class="python">In [1]: s = 'the brown fox'

In [2]: s.title()
Out[2]: 'The Brown Fox'</code>

The .title() method is highly effective for both ASCII and Unicode strings, as shown below:

<code class="python">In [3]: "hello world".title()
Out[3]: 'Hello World'

In [4]: u"hello world".title()
Out[4]: u'Hello World'</code>

However, it's important to be aware of its behavior with embedded apostrophes. As mentioned in the documentation, the algorithm defines a word as a group of consecutive letters. This means that apostrophes in contractions and possessives can form word boundaries:

<code class="python">In [5]: "they're bill's friends from the UK".title()
Out[5]: "They'Re Bill'S Friends From The Uk"</code>

This behavior may not be the desired result in all cases, so it is worth considering if the string contains embedded apostrophes.
