Sample Solution:

Python Code:

``````#License: https://bit.ly/3oLErEI

def test(strs):
return strs.replace("-", " " * 3).replace("_", " ")

strs = "Python-Exercises"
print("Original strings:",strs)
print("Depth of groups of matched nested parentheses separated by parentheses:")
print(test(strs))
strs = "Python_Exercises"
print("\nOriginal strings:",strs)
print("Depth of groups of matched nested parentheses separated by parentheses:")
print(test(strs))
strs = "-Hello,_world!__This_is-so-easy!-"
print("\nOriginal strings:",strs)
print("Depth of groups of matched nested parentheses separated by parentheses:")
print(test(strs))
``````

Sample Output:

```Original strings: Python-Exercises
Depth of groups of matched nested parentheses separated by parentheses:
Python   Exercises

Original strings: Python_Exercises
Depth of groups of matched nested parentheses separated by parentheses:
Python Exercises

Original strings: -Hello,_world!__This_is-so-easy!-
Depth of groups of matched nested parentheses separated by parentheses:
Hello, world!  This is   so   easy!
```
