Python - Strings with Maximum K length

Python - Strings with Maximum K length

Let's delve into the topic of handling strings with a maximum length of k in Python. There are various operations we might want to perform with this constraint, and I'll cover a few of them here.

1. Truncating a String to a Maximum Length

If you have a string and you want to ensure it doesn't exceed a maximum length of k, you can simply slice it:

def truncate_string(s, k): return s[:k] s = "Hello, World!" print(truncate_string(s, 5)) # Output: Hello

2. Splitting a String into Chunks of Size k

If you want to split a long string into chunks of size k:

def split_string_into_chunks(s, k): return [s[i:i+k] for i in range(0, len(s), k)] s = "This is a test string to be split." print(split_string_into_chunks(s, 5)) # Output: ['This ', 'is a ', 'test ', 'strin', 'g to ', 'be sp', 'lit.']

3. Filtering a List of Strings to Keep Only Those with Length �� k

If you have a list of strings and you want to keep only those whose length doesn't exceed k:

def filter_by_length(strings, k): return [s for s in strings if len(s) <= k] strings = ["apple", "banana", "cherry", "date", "fig"] print(filter_by_length(strings, 5)) # Output: ['apple', 'date', 'fig']

4. Pad Strings with Zeroes (or any character) up to Length k

If you need every string to be exactly of length k by padding with zeroes (or any other character):

def pad_string(s, k, char='0'): return s.ljust(k, char) s = "42" print(pad_string(s, 5)) # Output: 42000

5. Check If All Strings in a List are of Length k

def check_all_strings_length(strings, k): return all(len(s) == k for s in strings) strings = ["apple", "peach", "cherr"] print(check_all_strings_length(strings, 5)) # Output: True

These are just a few common operations you might perform with strings and a length constraint. Depending on your specific needs, there are many other possible operations and manipulations related to this topic.
