**Creation:**
|
|
|
|
An empty `string` is created using a pair of quotation marks or apostrophes:
|
|
```shell
|
|
>>> new_string = ''
|
|
>>> type(new_string)
|
|
<class 'string'>
|
|
>>> len(new_string)
|
|
0
|
|
```

|
|
|
|
* `string.find('you')` Returns the lowest position that the substring is found at.
|
|
|
|
* `str.join(iterable)` Join all elements in an `iterable` with a specified string.
|
|
|
|
* `str.replace(old, new, max)` method is used to replace the substring `old` with the string `new` for a total of `max` times. This method returns a new copy of the string with the replacement, and the original `str` is unchanged.
|
|
|
|
* `string.split(separator, maxsplit)` Returns a list of substrings delimited by the `separator`, an optional `maxsplit` number of times, and if not specified, the string will be split on all instances of the `separator`.
|
|
|
|
* `string.strip(to_strip)` Returns a string with `to_strip` removed from both the beginning and the end of the string. If `to_strip` is not specified, this will strip all whitespace characters.
|
|
|
|
* `string.format(to_add)` Returns a formatted string with parameter `to_add` placed in the placeholder position. The placeholder has to be defined by a pair of curly braces {} int the `string`'s value. The parameter, `to_add` can be anything amongst an integer, a floating point numerical, a string or even variables.
