在引号中使用引号

When I want to do a print command in Python and I need to use quotation marks, I don't know how to do it without closing the string.

当我想在Python中执行打印命令并且需要使用引号时，我不知道如何在不关闭字符串的情况下执行。

For instance:

例如:

print " "a word that needs quotation marks" "

But when I try to do what I did above, I end up closing the string and I can't put the word I need between quotation marks.

但是当我尝试做上面所做的事情时，我最终关闭了字符串，我不能在引号之间加上我需要的单词。

How can I do that?

我怎么做呢?

You could do this in one of three ways:

你可以用以下三种方法之一:

1) Use single and double quotes together:

1)使用单引号和双引号:

>>> print '"A word that needs quotation marks"'
"A word that needs quotation marks"

2) Escape the double quotes within the string:

2)转义字符串中的双引号:

>>> print "\"A word that needs quotation marks\""
"A word that needs quotation marks"

3) Use triple-quoted strings:

3)使用三引号字符串:

>>> print """ "A word that needs quotation marks" """
"A word that needs quotation marks"

#2

You need to escape it:

你需要摆脱它:

>>> print "The boy said \"Hello!\" to the girl"
The boy said "Hello!" to the girl
>>> print 'Her name\'s Jenny.'
Her name's Jenny.

See the python page for string literals.

请参阅python页面中的字符串文字。

#3

Python accepts both " and ' as quote marks, so you could do this as:

Python接受“和”作为引号，因此您可以这样做:

>>> print '"A word that needs quotation marks"'
"A word that needs quotation marks"

Alternatively, just escape the inner "s

或者，只是逃离内心的“s”。

>>> print "\"A word that needs quotation marks\""
"A word that needs quotation marks"

#4

Use the literal escape character \

使用文字转义字符\

print("Here is, \"a quote\"")

The character basically means ignore the semantic context of my next charcter, and deal with it in its literal sense.

这个字符基本上是指忽略我下一个角色的语义上下文，并按字面意思处理它。

in Python 3.2.2 on Windows,

在Python 3.2.2中，

print(""""A word that needs quotation marks" """)

is ok. I think it is the enhancement of Python interpretor.

就可以了。我认为这是Python解释器的改进。

One case which is prevalent in duplicates is the requirement to use quotes for external processes. A workaround for that is to not use a shell, which removes the requirement for one level of quoting.

在副本中普遍存在的一种情况是对外部进程使用引号的要求。解决这个问题的方法是不使用shell，这就消除了对一级引用的要求。

os.system("""awk '/foo/ { print "bar" }' %""" % filename)

can usefully be replaced with

可以被有用的替代吗

subprocess.call(['awk', '/foo/ { print "bar" }', filename])

(which also fixes the bug that shell metacharacters in filename would need to be escaped from the shell, which the original code failed to do; but without a shell, no need for that).

(它还修复了在文件名中shell元字符需要从shell中转义的错误，这是原始代码没有做到的;但没有壳，就没有必要这么做)。

Of course, in the vast majority of cases, you don't want or need an external process at all.

当然，在大多数情况下，您根本不需要或根本不需要外部过程。

with open(filename) as fh:
    for line in fh:
        if 'foo' in line:
            print("bar")

You could also try string addition: print " "+'"'+'a word that needs quotation marks'+'"'

您还可以尝试字符串添加:打印“”+“”+“+”一个需要引号的词“+”

#8

When you have several words like this which you want to concatenate in a string, I recommend using format or f-strings which increase readability dramatically (in my opinion).

当你有几个像这样的词想要连接到一个字符串时，我推荐使用格式或f-string，它们可以显著提高可读性(在我看来)。

To give an example:

举一个例子:

s = "a word that needs quotation marks"
s2 = "another word"

Now you can do

现在你能做的

print('"{}" and "{}"'.format(s, s2))

which will print

这将打印

"a word that needs quotation marks" and "another word"

As of Python 3.6 you can use:

在Python 3.6中，您可以使用:

print(f'"{s}" and "{s2}"')

yielding the same output.

产生相同的输出。
