<p>I am looking to format a number like 188518982.18 to £188,518,982.18 using Python.</p>

<p>How can I do this?</p>

See the
locale
module.
This does currency (and date) formatting.
```
```
>>> import locale
>>> locale.setlocale( locale.LC_ALL, '' )
'English_United States.1252'
>>> locale.currency( 188518982.18 )
'$188518982.18'
>>> locale.currency( 188518982.18, grouping=True )
'$188,518,982.18'
```
```
