How to ignore the escaping \ python list?

问题

I want to ignore the escape character in the following code.

>>> a=['\%']
>>> print a
['\\%']

I want to output like ['\%']. Is there any way to do that?

回答1:

Using string_escape, unicode_escape encoding (See Python Specific Encodings):

>>> a = ['\%']
>>> print str(a).decode('string_escape')
['\%']
>>> print str(a).decode('unicode_escape')
['\%']

回答2:

Couple of manual ways:

>>> a=['\%']
>>> print "['{}']".format(a[0])
['\%']
>>> print "['%s']" % a[0]
['\%']

Or more generally:

>>> a=['\%', '\+']
>>> print '[{}]'.format(', '.join("'{}'".format(i) for i in a))
['\%', '\+']
>>> print '[%s]' % ', '.join("'%s'" % i for i in a)
['\%', '\+']
