# 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!

**Pictorial Presentation:**

**Sample Solution:**

**Python Code:**

```

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!

## Python: Tips of the Day

**Clamps num within the inclusive range specified by the boundary values x and y:**

Example:

def tips_clamp_num(num,x,y): return max(min(num, max(x, y)), min(x, y)) print(tips_clamp_num(2, 4, 6)) print(tips_clamp_num(1, -1, -6))

Output:

4 -1
