I have the following code

test = "have it break."
selectiveEscape = "Print percent % in sentence and not %s" % test

print(selectiveEscape)

I would like to get the output:

Print percent % in sentence and not have it break.

What actually happens:

    selectiveEscape = "Use percent % in sentence and not %s" % test
TypeError: %d format: a number is required, not str

>>> test = "have it break."
>>> selectiveEscape = "Print percent %% in sentence and not %s" % test
>>> print selectiveEscape
Print percent % in sentence and not have it break.

How can I selectively escape percent (%) in Python strings , , which contains normal text together with "argument specifiers", special symbols like "%s" and "%d". To selectively escape per cent (%) in Python strings you can use the following piece of code:-test = "have it break." selectiveEscape = "Print percent %% in sentence and not %s" % test . print(selectiveEscape)


Alternatively, as of Python 2.6, you can use new string formatting (described in PEP 3101):

'Print percent % in sentence and not {0}'.format(test)

which is especially handy as your strings get more complicated.

String Formatting - Learn Python, ' is most often used in conjunction with the % operator for strings. You can't selectively escape %, as % always has a special meaning depending on the following character. In the documentation of Python, at the bottem of the second table in that section, it states: '%' No argument is converted, results in a '%' character in the result.


try using %% to print % sign .

What does '%s' mean in python?, . It's described as: x % y remainder of x / y. So it gives you the remainder/rest that remains if you "floor divide" x by y. It is easy to be drawn to the urlencode function in the Python urllib module documentation. But for simple escaping, only quote_plus, or possibly quote is needed. I believe this is the appropriate solution to Python urlencode annoyance and O'Reilly's Amazon Hack #92. For reference: Percent-encoding on Wikipedia


You can't selectively escape %, as % always has a special meaning depending on the following character.

In the documentation of Python, at the bottem of the second table in that section, it states:

'%'        No argument is converted, results in a '%' character in the result.

Therefore you should use:

selectiveEscape = "Print percent %% in sentence and not %s" % (test, )

(please note the expicit change to tuple as argument to %)

Without knowing about the above, I would have done:

selectiveEscape = "Print percent %s in sentence and not %s" % ('%', test)

with the knowledge you obviously already had.

What does the percentage sign mean in Python, How can I selectively escape percent (%) in Python strings? I have the following code test = "have it  How can we change y axis to percent, instead of a fraction using Plotnine library in Python? A MWE of a barplot is as follows: from plotnine import * from plotnine.data import mpg. p = ggplot(mpg) + geom_bar(aes(x='manufacturer', fill='class'), position='fill') print(p) Which gives the following figure: Stacked bar chart with y axis as fraction


If the formatting template was read from a file, and you cannot ensure the content doubles the percent sign, then you probably have to detect the percent character and decide programmatically whether it is the start of a placeholder or not. Then the parser should also recognize sequences like %d (and other letters that can be used), but also %(xxx)s etc.

Similar problem can be observed with the new formats -- the text can contain curly braces.

How can I selectively escape percent (%) in Python strings?, Alternatively, as of Python 2.6, you can use new string formatting (described in PEP 3101): 'Print percent % in sentence and not {0}'.format(test). However, Python also has an alternate way for string formatting via the format() function. We will explore the key differences between the ‘%’ operator and the string.format() function in this post. Python String.Format() Or Percentage (%) for Formatting. Let’s first dig into the percentage (%) sign and see what it does.
