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