Method#5: Using the reduce() function from the functools module: In step 2, we are iterating over the string, which takes O(n) time.In step 3, we are storing each pair in a list, which takes constant time.In step 4, we are flattening the list and joining the character pairs with a comma, which takes O(n) time.Therefore, the overall time complexity is O(n).Space complexity: O(n). Lets take another look at the first .split() call: unsplit.split('\n')[1:]. This is essentially to extension of the ASCII personality set in that it includes all the ASCII drawing the an other 128 character codes. However, it loads string information in a list of lists, each holding a unique row of information you want to write out to a CSV file: Your output should be a single string that looks like this: For this solution, I used a list comprehension, which is a powerful feature of Python that allows you to rapidly build lists.

"Wouldn't the sentence 'I want to put a hyphen between the words Fish and And and And and Chips in my Fish-And-Chips sign' have been clearer if quotation marks had been placed before Fish, and between Fish and and, and and and And, and And and and, and and and And, and And and and, and and and Chips, as well as after Chips?" Write A Python Program That Accepts A Hyphen Separated Sequence? Notice that when entering a hyphenated word or phrase into an equation in the Equation Editor, such as "How-To Geek", there are spaces before and after the dash. Then list comprehension is responsible to convert the tuples to list of strings and at last, result is joined using the join function. Why did DOS-based Windows require HIMEM.SYS to boot? sort () print('-'. I have a list of values which looks like: I want to add a hyphen after the name and this should look like: So the logic is that if there is a "." 566), Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI.

If n is less than or equal to 2, return s. Otherwise, concatenate the first two characters of s with sep. Recursively call insert_separator() with the remaining substring starting at index 2. acknowledge that you have read and understood our, Data Structure & Algorithm Classes (Live), Data Structures & Algorithms in JavaScript, Data Structure & Algorithm-Self Paced(C++/JAVA), Full Stack Development with React & Node JS(Live), Android App Development with Kotlin(Live), Python Backend Development with Django(Live), DevOps Engineering - Planning to Production, GATE CS Original Papers and Official Keys, ISRO CS Original Papers and Official Keys, ISRO CS Syllabus for Scientist/Engineer Exam, Program to replace every space in a string with hyphen, BrowserStack Interview Experience | Set 2 (Coding Questions), BrowserStack Interview Experience | Set 3 (Coding Questions), BrowserStack Interview Experience | Set 4 (On-Campus), BrowserStack Interview Experience | Set 5 (Fresher), BrowserStack Interview Experience | Set 6 (On-Campus), BrowserStack Interview Experience | Set 7 (Online Coding Questions), BrowserStack Interview Experience | Set 1 (On-Campus), Remove comments from a given C/C++ program, C++ Program to remove spaces from a string, URLify a given string (Replace spaces with %20), Program to print all palindromes in a given range, Check if characters of a given string can be rearranged to form a palindrome, Rearrange characters to form palindrome if possible, Check if a string can be rearranged to form special palindrome, Check if the characters in a string form a Palindrome in O(1) extra space, Sentence Palindrome (Palindrome after removing spaces, dots, .. etc), Python program to check if a string is palindrome or not, Reverse words in a given String in Python, Different Methods to Reverse a String in C++. join ( items)) Sample Output: green-red-black-white black-green-red-white What is the difference between __str__ and __repr__? You can go from a list to a string in Python with the join() method. Below is my solution, starting with a list of lists and ending with a single string: Here we use .join() not once, but twice. Split the hyphen-separated strings into a list of strings using the split () function and store it in a variable. The time complexity of this function is O(n), where n is the length of the input string, because it visits each character in the string exactly once. Copyright 2019-2023 www.copyassignment.com. Well in Python too, for the string data type, we say the same definition. We just need to add hyphens or dash: - between each alphabet in the entered or desired string by the user.

Split strings is another function that can be applied in Python let see for string "guru99 career guru99". Method #1 : Using join() + list comprehension The combination of above method can be used to perform this particular task. pre-logic code block might work better as: as stated in some comments, it is not necessary to use a pre-logic code block, but if you choose to do so, this should help.
