Converts a string to camelcase.
|
|
|
|
Use `re.sub()` to replace any `-` or `_` with a space, using the regexp `r"(_|-)+"`.
|
|
Use `title()` to capitalize the first letter of each word convert the rest to lowercase.
|
|
Finally, use `replace()` to remove spaces between words.
|
|
|
|
```py
|
|
from re import sub
|
|
|
|
def camel(s):
|
|
s = 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'
|
|
```
