Write a function that returns the count of characters that have to be removed in order to get a string with no consecutive repeats.
*Note:* This includes any characters
##  Examples
```python
'abbbbc'  => 'abc'    #  answer: 3
'abbcca'  => 'abca'   #  answer: 2
'ab cca'  => 'ab ca'  #  answer: 1
```
def count_repeats(str):
    return sum(a == b for a, b in zip(str, str[1:]))
def count_repeats(str):
    return sum(a == b for a, b in zip(str, str[1:]))
