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.
