There is not typecast and no type coercion in Python. You have to convert your variable in an explicit way.

To convert an object in string you use the <code>str()</code> function. It works with any object that has a method called <code>__str__()</code> defined. In fact

<pre><code>str(a)
</code></pre>

is equivalent to

<pre><code>a.__str__()
</code></pre>

The same if you want to convert something to int, float, etc.

blocks|key|1537298|text|在Python+=>+3.6中，您可以使用f格式：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1537299|>>>+int_value+=+10

'10'

In Python => 3.6 you can use <code>f</code> formatting:

<pre><code>&gt;&gt;&gt; int_value = 10
&gt;&gt;&gt; f'{int_value}'
'10'
&gt;&gt;&gt;
</code></pre>

blocks|key|1321955|text|在我看来，最得体的方式是。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1321956|i+=+32+++-->++++`i`+==+'32'|code-block|syntax|javascript|1321957|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|$]]

The most decent way in my opinion is ``.

<pre><code>i = 32 --&gt; `i` == '32'
</code></pre>

blocks|key|1537229|text|您可以使用%25s或.format|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1537230|>>>+"%25s"+%25+10
'10'

You can use <code>%s</code> or <code>.format</code>:
<pre><code>&gt;&gt;&gt; &quot;%s&quot; % 10
'10'
&gt;&gt;&gt;
</code></pre>
Or:
<pre><code>&gt;&gt;&gt; '{}'.format(10)
'10'

blocks|key|1537403|text|随着Python3.6中f-strings的引入，这也将起作用：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1537404|f'{10}'+==+'10'|code-block|syntax|javascript|1537405|它实际上比调用str()更快，但代价是可读性。|style|CODE|1537406|事实上，它比%25x字符串格式化和.format()更快！|1537407|entityMap|0|LINK|mutability|MUTABLE|url|https://www.python.org/dev/peps/pep-0498/^0|C|9|0|0|0|7|5|0|6|2|F|9|0^^$0|@$1|2|3|4|5|6|7|W|8|@]|9|@$A|X|B|Y|1|Z]]|C|$]]|$1|D|3|E|5|F|7|10|8|@]|9|@]|C|$G|H]]|$1|I|3|J|5|6|7|11|8|@$A|12|B|13|K|L]]|9|@]|C|$]]|$1|M|3|N|5|6|7|14|8|@$A|15|B|16|K|L]|$A|17|B|18|K|L]]|9|@]|C|$]]|$1|O|3|-4|5|6|7|19|8|@]|9|@]|C|$]]]|P|$Q|$5|R|S|T|C|$U|V]]]]

With the introduction of <a href="https://www.python.org/dev/peps/pep-0498/" rel="nofollow noreferrer">f-strings</a> in Python 3.6, this will also work:
<pre><code>f'{10}' == '10'
</code></pre>
It is actually faster than calling <code>str()</code>, at the cost of readability.
In fact, it's faster than <code>%x</code> string formatting and <code>.format()</code>!

There are several ways to convert an integer to string in python.
You can use [ str(integer here) ] function, the f-string [ f'{integer here}'], the .format()function [ '{}'.format(integer here) and even the '%s'% keyword [ '%s'% integer here]. All this method can convert an integer to string.
See below example
<pre><code>#Examples of converting an intger to string

#Using the str() function
number = 1
convert_to_string = str(number)
print(type(convert_to_string)) # output (&lt;class 'str'&gt;)

#Using the f-string
number = 1
convert_to_string = f'{number}'
print(type(convert_to_string)) # output (&lt;class 'str'&gt;)

#Using the {}'.format() function
number = 1
convert_to_string = '{}'.format(number)
print(type(convert_to_string)) # output (&lt;class 'str'&gt;)

#Using the '% s '% keyword
number = 1
convert_to_string = '% s '% number
print(type(convert_to_string)) # output (&lt;class 'str'&gt;)

I want to convert an integer to a string in Python. I am typecasting it in vain:
<pre><code>d = 15
d.str()
</code></pre>
When I try to convert it to string, it's showing an error like <code>int</code> doesn't have any attribute called <code>str</code>.

Converting integer to string in Python

我想在Python中将整数转换为字符串。我是在徒劳无功地键入它：d = 15d.str()当我试图将它转换成字符串时，它显示了一个错误，比如int没有任何名为str的属性。
