# Python: Expand Spaces

## Python Programming Puzzles: Exercise-99 with Solution

Write a Python program to find a string such that, when three or more spaces are compacted to a '-' and one or two spaces are replaced by underscores, leads to the target.

Input: Python-Exercises Output: Python Exercises Input: Python_Exercises Output: Python Exercises Input: -Hello,_world!__This_is-so-easy!- Output: Hello, world! This is so easy!

**Visual Presentation:**

**Sample Solution:**

**Python Code:**

```
# License: https://bit.ly/3oLErEI
# Function to replace hyphens with three spaces and underscores with a single space
def test(strs):
return strs.replace("-", " " * 3).replace("_", " ")
# Test cases with different strings
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!
