Decapitalizes the first letter of a string.
|
|
|
|
- Use list slicing and `str.lower()` to decapitalize the first letter of the string.
|
|
- Use `str.join()` to combine the lowercase first letter with the rest of the characters.
|
|
- Omit the `upper_rest` parameter to keep the rest of the string intact, or set it to `True` to convert to uppercase.
|
|
|
|
```py
|
|
def decapitalize(s, upper_rest = False):
|
|
return ''.join([s[:1].lower(), (s[1:].upper() if upper_rest else s[1:])])
|
|
```
|
|
|
|
```py
|
|
decapitalize('FooBar') # 'fooBar'
|
|
decapitalize('FooBar', True) # 'fOOBAR'
|
|
```
