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#@!']

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#@!']

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:
