Python: Check whether any word in a given sting contains duplicate characrters or not
Python String: Exercise-100 with Solution
Write a Python program to check whether any word in a given sting contains duplicate characrters or not. Return True or False.
Sample Solution-1:
Python Code:
def duplicate_letters(text):
word_list = text.split()
for word in word_list:
if len(word) > len(set(word)):
return False
return True
text = "Filter out the factorials of the said list."
print("Original text:")
print(text)
print("Check whether any word in the said sting contains duplicate characrters or not!")
print(duplicate_letters(text))
text = "Python Exercise."
print("\nOriginal text:")
print(text)
print("Check whether any word in the said sting contains duplicate characrters or not!")
print(duplicate_letters(text))
text = "The wait is over."
print("\nOriginal text:")
print(text)
print("Check whether any word in the said sting contains duplicate characrters or not!")
print(duplicate_letters(text))
Sample Output:
Original text: Filter out the factorials of the said list. Check whether any word in the said sting contains duplicate characrters or not! False Original text: Python Exercise. Check whether any word in the said sting contains duplicate characrters or not! False Original text: The wait is over. Check whether any word in the said sting contains duplicate characrters or not! True

Sample Solution-2:
Python Code:
def duplicate_letters(text):
return all(len(word) == len(set(word)) for word in text.split())
text = "Filter out the factorials of the said list."
print("Original text:")
print(text)
print("Check whether any word in the said sting contains duplicate characrters or not!")
print(duplicate_letters(text))
text = "Python Exercise."
print("\nOriginal text:")
print(text)
print("Check whether any word in the said sting contains duplicate characrters or not!")
print(duplicate_letters(text))
text = "The wait is over."
print("\nOriginal text:")
print(text)
print("Check whether any word in the said sting contains duplicate characrters or not!")
print(duplicate_letters(text))
Sample Output:
Original text: Filter out the factorials of the said list. Check whether any word in the said sting contains duplicate characrters or not! False Original text: Python Exercise. Check whether any word in the said sting contains duplicate characrters or not! False Original text: The wait is over. Check whether any word in the said sting contains duplicate characrters or not! True

Python: Tips of the Day
Check if a given key already exists in a dictionary:
In is the intended way to test for the existence of a key in a dict.
d = {"key1": 10, "key2": 23} if "key1" in d: print("this will execute") if "nonexistent key" in d: print("this will not")
If you wanted a default, you can always use dict.get():
d = dict() for i in range(100): key = i % 10 d[key] = d.get(key, 0) + 1
and if you wanted to always ensure a default value for any key you can either use dict.setdefault() repeatedly or defaultdict from the collections module, like so:
from collections import defaultdict d = defaultdict(int) for i in range(100): d[i % 10] += 1
but in general, the in keyword is the best way to do it.
