python中字符串模块

To solve this type of problem, we will use the **re module** or **regular expression module in the Python**. Here, we will assume a string given by the user from which we have to remove all consonants that is we have to find all vowels present in the given strings. So, before going to solve this problem we will learn a little bit about re module.

为了解决这类问题，我们将**在Python中**使用**re模块**或**正则表达式模块** 。 在这里，我们假设用户给定的字符串，我们必须从中删除所有辅音，即必须找到给定字符串中存在的所有元音。 因此，在解决此问题之前，我们将学习一些有关re模块的知识。

## 什么是Python中的re模块？ **(**What is re module in the Python?**)** ##

Python has an inbuilt module called **re** which allows us to solve the various problems based on pattern matching and string manipulation.

Python有一个名为**re**的内置模块，它使我们能够基于模式匹配和字符串处理来解决各种问题。

Let us assume a string s is given by the user it has a mixture of consonants and vowels. Here, we are going to write **Python code that will remove all consonants from the string** s.

让我们假设用户给定的字符串s混合了辅音和元音。 在这里，我们将编写**Python代码，该代码将从字符串** s中 **删除所有辅音** 。

s = 'Includehelp is specially designed to provide help to students, working professionals and job seekers. We are fully dedicated to making each tutorial very simple to learn and understand.'

**Code:**

**码：**

# importing the module
    import re
    
    # string initialization
    s ='Includehelp is specially designed to provide help to students, working professionals and job seekers. We are fully dedicated to making each tutorial very simple to learn and understand.'
    
    # removing all constants
    s1=re.sub('[^aeiouAEIOU ]+','',s)
    
    # printing the string after removing all constants
    print(s1)

**Output**

**输出量**

Iuee i eia eie o oie e o ue oi oeioa a o eee e ae u eiae o ai ea uoia e ie o ea a uea

**Explanation:**

**说明：**

*  Here, we have included the **re module** in the Python code by using the import function.
    
    在这里，我们通过使用import函数将**re模块**包含在Python代码中。
 *  In **re module**, **re.sub** use to replace the substring. The syntax of **re.sub()** is **re.sub(Pattern, replace, string)** and in the above code, we are replacing all letters with **''** (empty space) excepting the vowel **"aeiouAEIOU"**.
    
    在**re module中** ， **re.sub**用于替换子字符串。 **re.sub()**的语法是**re.sub(Pattern，replace，string)** ，在上面的代码中，我们将所有字母替换为**''** (空白)，但元音**“ aeiouAEIOU”**除外。
 *  At the end of the program, we are printing the left string after the replacement of all consonants and this is our requirement.
    
    在程序结束时，我们将在替换所有辅音后打印左字符串，这是我们的要求。
