Python: Find the set of distinct characters in a string, ignoring case
Python Programming Puzzles: Exercise-42 with Solution
Write a Python program to find the set of distinct characters in a given string, ignoring case.
Input: HELLO Output: ['h', 'o', 'l', 'e'] Input: HelLo Output: ['h', 'o', 'l', 'e'] Input: Ignoring case Output: ['s', 'n', 'c', 'o', 'e', 'i', 'r', 'g', 'a', ' ']

Sample Solution-1:
Python Code:
#License: https://bit.ly/3oLErEI
def test(strs):
return [*set(strs.lower())]
strs = "HELLO"
print("Original string:",strs)
print("Set of distinct characters in the said string, ignoring case:")
print(test(strs))
strs = "HelLo"
print("\nOriginal string:",strs)
print("Set of distinct characters in the said string, ignoring case:")
print(test(strs))
strs = "Ignoring case"
print("\nOriginal string:",strs)
print("Set of distinct characters in the said string, ignoring case:")
print(test(strs))
Sample Output:
Original string: HELLO Set of distinct characters in the said string, ignoring case: ['o', 'e', 'l', 'h'] Original string: HelLo Set of distinct characters in the said string, ignoring case: ['o', 'e', 'l', 'h'] Original string: Ignoring case Set of distinct characters in the said string, ignoring case: ['o', ' ', 'i', 'r', 'e', 'g', 'a', 'n', 'c', 's']

Sample Solution-2:
Python Code:
#License: https://bit.ly/3oLErEI
def test(strs):
return list(set(strs.lower()))
strs = "HELLO"
print("Original string:",strs)
print("Set of distinct characters in the said string, ignoring case:")
print(test(strs))
strs = "HelLo"
print("\nOriginal string:",strs)
print("Set of distinct characters in the said string, ignoring case:")
print(test(strs))
strs = "Ignoring case"
print("\nOriginal string:",strs)
print("Set of distinct characters in the said string, ignoring case:")
print(test(strs))
Sample Output:
Original string: HELLO Set of distinct characters in the said string, ignoring case: ['h', 'o', 'l', 'e'] Original string: HelLo Set of distinct characters in the said string, ignoring case: ['h', 'o', 'l', 'e'] Original string: Ignoring case Set of distinct characters in the said string, ignoring case: ['s', 'n', 'c', 'o', 'e', 'i', 'r', 'g', 'a', ' ']
