Having both single and double quotation in a python string

Question

Hi I\'m trying to have a string that contains both single and double quotation in python -- (\'\"). The reason I need this expression is to use as an input to some external

Answer 1

You can either (1) enclose the string in double quotes and escape the double quotes with a \ or (2) enclose the string in single quotes and escape the single quotes with a \. For example:

>>> print('She is 5\' 6" tall.')
She is 5' 6" tall.
>>> print("He is 5' 11\" tall.")
He is 5' 11" tall.

Answer 2

Use triple-quoted strings:

""" This 'string' contains "both" types of quote """
''' So ' does " this '''

Answer 3

To add both the single and double quote on python use screened (escaped) quotes. Try this for example:

print(" just display ' and \" ")

The \" tells python this is not the end of the quoted string.

Answer 4

The actual problem is , the print() statement doesn't print the \ but when you refer to the value of the string in the interpreter, it displays a "\" whenever an apostrophe is used . For instance, refer the following code:

    >>> s = "She said, \"Give me Susan's hat\""
    >>> print(s)
    She said, "Give me Susan's hat"
    >>> s
    'She said, "Give me Susan\'s hat"'

This is irrespective of whether you use single, double or triple quotes to enclose the string.

    >>> s = """She said, "Give me Susan's hat" """
    >>> s
    'She said, "Give me Susan\'s hat" '

Another way to include this :

    >>> s = '''She said, "Give me Susan's hat" '''
    >>> s
    'She said, "Give me Susan\'s hat" '
    >>> s =  '''She said, "Give me Susan\'s hat" '''
    >>> s
    'She said, "Give me Susan\'s hat" '

So basically, python doesn't remove the \ when you refer to the value of s but removes it when you try to print. Despite this fact, when you refer to the length of s, it doesn't count the "\". For eg.,

    >>> s = '''"''"'''
    >>> s
    '"\'\'"'
    >>> print(s)
    "''"
    >>> len(s)
    4

Answer 5

Although its more verbose, an alternative way would be to do the following:

str1 = 'the part that has double "s" in it'

str1 = str1 + " the part that has single 's' in it"

Answer 6

Use triple quotes.

"""Trip'le qu"oted"""

or

'''Ag'ain qu"oted'''

Keep in mind that just because Python reprs a string with backslashes, doesn't mean it's actually added any slashes to the string, it may just be showing special characters escaped.

Using an example from the Python tutorial:

>>> len('"Isn\'t," she said.')
18
>>> len('''"Isn't," she said.''')
18

Even though the second string appears one character shorter because it doesn't have a backslash in it, it's actually the same length -- the backslash is just to escape the single quote in the single quoted string.

Another example:

>>> for c in '''"Isn't," she said.''':
...     sys.stdout.write(c)
... 
"Isn't," she said.
>>> 

If you don't let Python format the string, you can see the string hasn't been changed, it was just Python trying to display it unambiguously.

See the tutorial section on strings.
