# Basic String Methods

## Basic String Methods

```python
sentence = 'something'

sentence.upper() # Upercases the sentance variable

print(sentence) # even though the method .upper ran the string within the sentence variable is still lowercase

# To get that data working you need to assign it to a variable:
up_sen = sentence.upper
# Or re-assign it to itself
sentence = sentence.upper()
```

#### Every time you see `()` we are working with a `function` or a `method`

## Difference between function and Method:

* if there is a `.` before the word then it is a method
  * example: `sentence.upper()`
  * methods also are associated with an object

* if it is stand alone then it is a function
  * example: `print()`
  * functions are stand alone

## Some Types of methods:

* `.upper` - Uppercase letters
* `.lower` - Lowercase letters
* `.capitalize` - Capitalizez first letter and lowercase the rest
* `.isdigit` - Checks if the string is a digit and returns a boolean value (True or False)
* There are multiple methods starting with `is` - Used to check: `is something like that?`
* There are multiple methods starting with `startswith()`
  * expects string
* Similar to `startswith` there is also `endswith()`
  * expects string
*
