python reverse string

In bioinformatics analysis, a series of operations are often performed on DNA sequences, including sub-sequence interception, complementary sequence acquisition, reverse sequence acquisition, and reverse complementary sequence acquisition. In the Python language, you can write the following functions to accomplish these simple functions.Sub-sequence interceptionU

This article mainly describes the python implementation of the specified input string reverse output of 6 methods, with a certain reference value, interested in small partners can refer to For a given string, reverse output, this task is a very simple operation for

Let's talk about reverse string in Python. Reversing strings by word is a common interview question. It is very easy to implement in Python. def reverse_string_by_word(s): lst = s.split() # split by blank space by default return ' '.join(lst[::-1])s = 'Power of Love'print reverse_string_by_word(s)# Love of Powers = 'He

= 'Hello World!'>>> re.split(r'\s+', s) # will discard blank spaces['Hello', 'World!']>>> re.split(r'(\s+)', s) # will keep spaces as a group['Hello', ' ', 'World!']>>> s = ' If you think that the reverse sequence is not highly readable by using slice, you can also write it like this. >>> ''.join(reversed(re.split(r'(\s+|\w+)', s)))'> !COM.EF to Welcome So easy! Python flip

Given an input string, reverse the string word by word.For example,Given s = " the sky is blue ",Return " blue is sky the ".Update (2015-02-12):For C programmers:try to solve it in-place in O(1) space.Linear time:1. Go through the string detect whether the "if not append the char to Word2 If the place is ' and word was

Reverse vowels of a StringWrite a function that takes a string as input and reverse only the vowels of a string.Example 1:Given s = "Hello", Return "Holle".Example 2:Given s = "Leetcode", Return "Leotcede". The vowels in the string are arranged in reverse order, and th

Reverse string, reverse string in C Language Through this article, you will learn how to simply optimize algorithms and programming the basic method-apply, at the same time, you will better understand the string.Start with an integer array. Suppose there is (int []) {, 5}, and you want to change it to (int []) {5, 4,

The C language uses pointers and arrays to implement reverse string and reverse string order. 1. The Array Implementation (without using string functions) program is as follows: 1 void ReverseByArray(char * s) 2 { 3 int len = 0; 4 while (s[len] != '\0') 5 le

In the previous article, we have derived two non-sequential memory blocks with different reverse lengths based on the two continuous memory blocks algorithms. In this article, I will use the algorithm previously analyzed to solve a more complex problem: Reversing words in a string. IntroductionThere is an algorithm question:Problem: reverse wordsComment: Write a
