Python - Find words greater than given length

When it is required to find words that are greater than a specific length, we can define a method that splits the string and iterates through it. It checks the length of each word and compares it with the given length. If the word length is greater, it is added to the result.

Using a Custom Function

Below is a demonstration using a custom function ?

def string_check(string_length, my_string):
    result_string = []
    words = my_string.split(" ")
    for x in words:
        if len(x) > string_length:
            result_string.append(x)
    return result_string

string_length = 3
my_string = "Python is always fun to learn"

print("The string is :")
print(my_string)
print("\nThe words in the string with length greater than", string_length, "is :")
print(string_check(string_length, my_string))

The string is :
Python is always fun to learn

The words in the string with length greater than 3 is :
['Python', 'always', 'learn']

Using List Comprehension

A more concise approach using list comprehension ?

my_string = "Python is always fun to learn"
min_length = 4

words = my_string.split()
result = [word for word in words if len(word) > min_length]

print("Original string:", my_string)
print(f"Words longer than {min_length} characters:", result)

Original string: Python is always fun to learn
Words longer than 4 characters: ['Python', 'always', 'learn']

Using Filter Function

Using the built-in filter() function with a lambda ?

my_string = "Python programming is really amazing"
min_length = 5

words = my_string.split()
result = list(filter(lambda word: len(word) > min_length, words))

print("Original string:", my_string)
print(f"Words longer than {min_length} characters:", result)

Original string: Python programming is really amazing
Words longer than 5 characters: ['Python', 'programming', 'really', 'amazing']

Comparison

Conclusion

List comprehension provides the most readable and efficient solution for filtering words by length. Use custom functions when you need additional processing logic beyond simple filtering.
