在Python中，字符串是一种常用的数据类型。对字符串的定义及表达方式有了了解后，接下来的学习，将为大家讲解如何使用Python来实现字符串的拼接。

1.加号拼接

s = “Hello” +  ” ” + “world” + ” I” print(s)

</pre>
输出结果：

<img loading="lazy" class="aligncenter size-full wp-image-11377" src="https://www.python51.com/wp-content/uploads/2021/04/1603417207799883.png" width="732" height="123" srcset="https://www.python51.com/wp-content/uploads/2021/04/1603417207799883.png 732w, https://www.python51.com/wp-content/uploads/2021/04/1603417207799883-240x40.png 240w, https://www.python51.com/wp-content/uploads/2021/04/1603417207799883-400x67.png 400w" sizes="(max-width: 732px) 100vw, 732px" />

2. ( ) 拼接

liststr = [‘Hello’,’World’,’I’] strlist = ”.join(liststr) print(‘转换后的数据类型是：’,type(strlist)) print(‘转换后的数据是：’,strlist)
<pre class="brush:js;toolbar:false">

输出结果：

3. 操作符拼接

s = “{} {}”.format(‘Hello’,’World’) print(‘输出结果是：’,s) s1 = “{0} {1}”.format(‘Hello’,’world’) print(‘s1的结果是 {}’.format(s1)) s2 = “{a} {b}”.format(a=’Hello’,b=’world’) print(‘s2的结果是 {}’.format(s2))

</pre>
输出结果：

<img loading="lazy" class="aligncenter size-full wp-image-11382" src="https://www.python51.com/wp-content/uploads/2021/04/1603417313248658.png" width="734" height="136" srcset="https://www.python51.com/wp-content/uploads/2021/04/1603417313248658.png 734w, https://www.python51.com/wp-content/uploads/2021/04/1603417313248658-240x44.png 240w, https://www.python51.com/wp-content/uploads/2021/04/1603417313248658-400x74.png 400w" sizes="(max-width: 734px) 100vw, 734px" />

4.（%）操作符进行拼接

s = “%s %s “%(‘Hello’,’world’) print(s)
<pre class="brush:js;toolbar:false">

输出结果：

5.通过（）进行拼接

s=(    ‘hello’ + ‘\n’    ”    ‘World’ + ‘\n’    ‘!’ ) print(s)

</pre>
输出结果：

<img loading="lazy" class="aligncenter size-full wp-image-11389" src="https://www.python51.com/wp-content/uploads/2021/04/1603417418855627.png" width="712" height="174" srcset="https://www.python51.com/wp-content/uploads/2021/04/1603417418855627.png 712w, https://www.python51.com/wp-content/uploads/2021/04/1603417418855627-240x59.png 240w, https://www.python51.com/wp-content/uploads/2021/04/1603417418855627-400x98.png 400w" sizes="(max-width: 712px) 100vw, 712px" />

6.F-string拼接 （该方法适用于版本）

s1=”Hello” s2=”World” print(f'{s1} {s2}’)
<pre class="brush:js;toolbar:false">

在版本不兼容报错：
