I think there is no use of using space literal match (/s) in the pattern. So I removed it and updated the snippet and it's document accordingly. Please review it and let me know if I am wrong.

Converts a string to camelcase.
|
|
|
|
Identify one or more groups containing the pattern with `-` or `_` using regexp `r"(_|-)+"` and replace the pattern with a `" "` (space literal) using `re.sub` method. Apply `title()` method on the obtained string to Capitalize the starting letter and lower the other letters of every word in the string. Finally, remove the spaces in the string using `replace()` method
|
|
|
|
```py
|
|
import re
|
|
|
|
def camel(s):
|
|
s = re.sub(r"(_|-)+", " ", s).title().replace(" ", "")
|
|
return s[0].lower() + s[1:]
|
|
```
|
|
|
|
```py
|
|
camel('some_database_field_name'); # 'someDatabaseFieldName'
|
|
camel('Some label that needs to be camelized'); # 'someLabelThatNeedsToBeCamelized'
|
|
camel('some-javascript-property'); # 'someJavascriptProperty'
|
|
camel('some-mixed_string with spaces_underscores-and-hyphens'); # 'someMixedStringWithSpacesUnderscoresAndHyphens'
|
|
```
