blocks|key|518658|text|Python是一种有趣的语言，虽然通常有一种(或两种)“显而易见”的方法来完成任何给定的任务，但灵活性仍然存在。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|518659|s+=+"string"
i+=+0

print+(s+%2B+repr(i))|code-block|syntax|javascript|518660|上面的代码片段是用Python3语法编写的，但是打印后的括号始终是允许的(可选)，直到版本3强制要求它们。|518661|希望这能有所帮助。|518662|凯特琳|518663|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|R|8|@]|9|@]|A|$]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

Python is an interesting language in that while there is usually one (or two) "obvious" ways to accomplish any given task, flexibility still exists.

<pre><code>s = "string"
i = 0

print (s + repr(i))
</code></pre>

The above code snippet is written in Python3 syntax but the parentheses after print were always allowed (optional) until version 3 made them mandatory.

Hope this helps.

blocks|key|518691|text|format()方法可用于连接字符串和整数|type|unstyled|depth|inlineStyleRanges|entityRanges|data|518692|print(s%2B"{}".format(i))|code-block|syntax|javascript|518693|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

format() method can be used to concatenate string and integer

<pre><code>print(s+"{}".format(i))
</code></pre>

blocks|key|301848|text|如果你只想打印，你可以这样做：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|301849|print(s+,+i)|code-block|syntax|javascript|301850|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

if you only want to print yo can do this:

<pre><code>print(s , i)
</code></pre>

blocks|key|301915|text|在python+3.6和更新版本中，您可以将其格式化为：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|301916|new_string+=+f'{s}+{i}'
print(new_string)|code-block|syntax|javascript|301917|或者只是：|301918|print(f'{s}+{i}')|301919|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

in python 3.6 and newer, you can format it just like this:
<pre><code>new_string = f'{s} {i}'
print(new_string)
</code></pre>
or just:
<pre><code>print(f'{s} {i}')
</code></pre>

blocks|key|518826|text|让我们假设您想要在如下情况下连接字符串和整数：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|518827|for+i+in+range(1,11):

Let's assume you want to concatenate string and integer in a situation like this:
<pre><code>for i in range(1,11):
 string=&quot;string&quot;+i 
</code></pre>
and you are getting type or concatenation error
The best way to go about it is to do something like this:
<pre><code>for i in range(1,11):
 print(&quot;string&quot;,i) 
</code></pre>
This will give you concatenated results like string 1, string 2, string 3 ...etc

In python say you have

<pre><code>s = "string"
i = 0
print s+i
</code></pre>

will give you error
so you write

<pre><code>print s+str(i) 
</code></pre>

to not get error.

I think this is quite a clumsy way to handle int and string concatenation.
Even Java does not need explicit casting to String to do this sort
of concatenation.
Is there a better way to do this sort of concatenation i.e without explicit casting in Python?

Concatenating string and integer in python

在python中，假设您有s = "string"i = 0print s+i会给你一个错误，所以你要写print s+str(i) 不会得到错误。我认为这是一种相当笨拙的处理int和字符串连接的方法。即使是Java也不需要显式地转换为String来进行这种连接。有没有更好的方法来做这种连接，也就是说，在Python中...
