# Python: Reverse the case of all strings. For those strings, which contain no letters, reverse the strings

## Python Programming Puzzles: Exercise-52 with Solution

Write a Python program to reverse the case of all strings. For those strings, which contain no letters, reverse the strings.

```Input:
['cat', 'catatatatctsa', 'abcdefhijklmnop', '124259239185125', '', 'foo', 'unique']
Output:
['CAT', 'CATATATATCTSA', 'ABCDEFHIJKLMNOP', '521581932952421', '', 'FOO', 'UNIQUE']

Input:
['Green', 'Red', 'Orange', 'Yellow', '', 'White']
Output:
['gREEN', 'rED', 'oRANGE', 'yELLOW', '', 'wHITE']

Input:
['Hello', '[email protected]#', '[email protected]#\$', '123#@!']
Output:
['hELLO', '[email protected]#', '[email protected]#\$', '123#@!']
```

Sample Solution:

Python Code:

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

def test(strs):
return [s[::-1] if s.isdigit() else s.swapcase() for s in strs]
strs = ['cat', 'catatatatctsa', 'abcdefhijklmnop', '124259239185125', '', 'foo', 'unique']
print("Original list:")
print(strs)
print("Reverse the case of all strings. For those strings which contain no letters, reverse the strings:")
print(test(strs))
strs = ['Green', 'Red', 'Orange', 'Yellow', '', 'White']
print("\nOriginal list:")
print(strs)
print("Reverse the case of all strings. For those strings which contain no letters, reverse the strings:")
print(test(strs))
strs = ["Hello", "[email protected]#", "[email protected]#\$", "123#@!"]
print("\nOriginal list:")
print(strs)
print("Reverse the case of all strings. For those strings which contain no letters, reverse the strings:")
print(test(strs))
``````

Sample Output:

```Original list:
['cat', 'catatatatctsa', 'abcdefhijklmnop', '124259239185125', '', 'foo', 'unique']
Reverse the case of all strings. For those strings which contain no letters, reverse the strings:
['CAT', 'CATATATATCTSA', 'ABCDEFHIJKLMNOP', '521581932952421', '', 'FOO', 'UNIQUE']

Original list:
['Green', 'Red', 'Orange', 'Yellow', '', 'White']
Reverse the case of all strings. For those strings which contain no letters, reverse the strings:
['gREEN', 'rED', 'oRANGE', 'yELLOW', '', 'wHITE']

Original list:
['Hello', '[email protected]#', '[email protected]#\$', '123#@!']
Reverse the case of all strings. For those strings which contain no letters, reverse the strings:
['hELLO', '[email protected]#', '[email protected]#\$', '123#@!']
```

## 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
```
