There are no multi-line comments in Python. They're both just strings. The former is typically used as a docstring and will be associated with the function/class/module, while the other gets assigned to a variable.

blocks|key|2365796|text|是的，它们是一样的。包含注释字符串作为函数或类的第一条语句是一种惯例。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2365797|见PEP+257+-+Docstring公约。|offset|length|2365798|entityMap|0|LINK|mutability|MUTABLE|url|http://www.python.org/dev/peps/pep-0257/^0|0|1|L|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

Yes, they are the same. It is a convention to include a comment string as the first statement of the function or a class.

Yes, they are the same

It is called a docstring

blocks|key|2365855|text|第一个片段不是注释。这是一根绳子。Python中的注释以#字符作为前缀。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2365856|entityMap^0|S|1|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

The first snippet is not a comment. It is a string. Comments in Python are prefixed by the <code>#</code> character.

blocks|key|3153559|text|第一个不是注释，而是一个字符串。但是，由于您没有使用该字符串执行任何操作(打印它，将它赋值给一个变量等等)。翻译所做的就是说：“是的，这是一个字符串，好吧！”完全无视它。实际上，它与注释相同，因为它是一组被解释器忽略的任意文本。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3153560|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

The first one isn't a comment, it's a string. But since you're not doing anything with that string (printing it, assigning it to a variable etc.) all the interpreter does is say "Yup, that's a string alright!" and ignore it entirely. Effectively making it the same as a comment, since it's an arbitrary bunch of text that's ignored by the interpreter.

<blockquote>
 are comments and strings the same in python?
</blockquote>

Strictly speaking, they are not the same. But in your question, what you refer to as "a comment" is actually a string. A comment is everything appearing in the same line after the <code>#</code> character.

a.py:

<pre><code>"""
comment1
"""
# comment2
</code></pre>

Now:

<pre><code>% strings a.pyc | grep comment
comment1
</code></pre>

As you can see, <code>comment2</code> is not part of the compiled byte code, while <code>comment1</code> is -- because it's not a comment, it's a string.

As others pointed out, the string is considered a <code>docstring</code>. <code>docstring</code>s are conventionally used for documenting your code, while comments are used, well, for commenting, and are not included in the documentation.

blocks|key|3153626|text|混乱是通过文件字符串产生的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3153627|这实际上不是一个注释，而是一种使用多行创建字符串的方法：|3153628|>>>+"""This+is+a+string
...+with+line+breaks"""
'This+is+a+string\nwith+line+breaks'|code-block|syntax|javascript|3153629|在类和函数中使用相同的符号来记录它们：|3153630|>>>+def+my_function():

'This+function+does+stupid+things.'
>>>+my_function()

++File+"<stdin>",+line+1,+in+<module>
++File+"<stdin>",+line+3,+in+my_function
ZeroDivisionError:+division+by+zero|3153631|所以你的代码：|3153632|somevariable+=+"""this+is+a+variable"""|3153633|实际上等于：|3153634|somevariable+=+"this+is+a+variable"|3153635|entityMap^0|0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|X|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|Y|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|Z|8|@]|9|@]|A|$]]|$1|K|3|L|5|F|7|10|8|@]|9|@]|A|$G|H]]|$1|M|3|N|5|6|7|11|8|@]|9|@]|A|$]]|$1|O|3|P|5|F|7|12|8|@]|9|@]|A|$G|H]]|$1|Q|3|R|5|6|7|13|8|@]|9|@]|A|$]]|$1|S|3|T|5|F|7|14|8|@]|9|@]|A|$G|H]]|$1|U|3|-4|5|6|7|15|8|@]|9|@]|A|$]]]|V|$]]

The confusion comes through docstrings.

This is actually not a comment, but a way to make a string with multiple lines:

<pre><code>&gt;&gt;&gt; """This is a string
... with line breaks"""
'This is a string\nwith line breaks'
</code></pre>

The same notation is used in classes and functions to document them:

<pre><code>&gt;&gt;&gt; def my_function():
... """This function does stupid things."""
... return 1/0
...
&gt;&gt;&gt; my_function.__doc__
'This function does stupid things.'
&gt;&gt;&gt; my_function()
Traceback (most recent call last):
 File "&lt;stdin&gt;", line 1, in &lt;module&gt;
 File "&lt;stdin&gt;", line 3, in my_function
ZeroDivisionError: division by zero
</code></pre>

So your code:

<pre><code>somevariable = """this is a variable"""
</code></pre>

is really just equal to:

<pre><code>somevariable = "this is a variable"
</code></pre>

I am just new to python. 
as i know in python multi-line comments are made like this

<pre><code>"""
this is a comments
"""
</code></pre>

but consider this code

<pre><code>somevariable="""this is a variable"""
print somevariable
</code></pre>

it prints this is a variable 
are comments and strings are same in python or they are different?
