What does '%s' mean in python?
What is Python?
Python is an object-oriented programming language that provides fast application development. It was released by Guido van Rossam in 1991. It has a huge demand in the rapid application development field due to its dynamic binding and dynamic typing options.
Python needs a unique syntax that covers readability that makes language easy and simple to learn. It enables code reuse and program modulity that supports modules and packages.What does '%s' mean in python?
Python '%' contains just one string literal that includes two punctuation marks. Percentage signature (%) in itself The dragon has just another character, engaging in quotes of any kind. There is nothing special about this.
However, '%' is often used in conjunction with the % operator for the wire. This operator suffers in much the same way for strings that are +and*. If I have an expression 'fu' + 'bar', it will evaluate as a result of 'fubar' (codification of two string literals). Expressions like '-' * 10 will evaluate in '----------' (ten hyphens). Note how the constriction and repetition of the wires correspond to arithmetic operations for addition and multiplication.
% operator usually arithmetic 0 "Modulus"Modulus"Modulus (which 0 "Balance 0 Also known as " is used in programming languages to calculate). So evaluate 3% 2 and 10% 3 both 1 (remaining of one partition by second).
in English "Modlo0 The technical use of the word is - for IQ: (0 "In addition to differences. For example, I can say that I have completed a list of change orders. This is broadly consistent with an expression: 'The project is completed except % % % %(project_name, change_list)... Where '%' 0 "Replaceable parameter expression0 ( or 0 "Token0 ") The string contains digits that will be replaced by string representations of the two variables that project_name and change_list.
There are many replaceable tokens that have a % operator on the right side of the 0 "Formatting string" may appear in " . These are documented here: 5. Built-in Type: String Formatting. For the most part these C programming language's standard libraries are compatible with the formatting characteristics of the printf() family of works... However they are more preferred than Sprintf() or Sprintf() than printf(). They evaluate in a new string whether your code is printing them or not.
As you'll see there are quite a few nuances for string formatting... They give you numerical precision and formatting, leading signs and hexadecimal representations with leading zeros, 0x or 0X (upper to lower case) prefixes, and scientific notations with E or E (lower or upper case) for exposure annotations, and so on.
There is also a special, Python specic formatting token: %R evaluated by the Python object of 0 "Representation0 is done in " . It's represented in the same way that a Python object produced in interactive interpreters and in some diagnostic production (such as in a stack trace printed by an undiscovered exception). It is mostly used for its own custom logging and clinical production. The ideal Python object can be the %R() of the R-Eval- uated in a similar object acceleration; But that is often not possible.
C style string formatting can be extremely difficult and sometimes downright frustrating. It is sometimes necessary to build your final string through a series of multiple formattic expressions to get a more complex form of output.
Modern versions of Python (from 2.6 and later and in 3.x) support a new and far more expressive form of string formatting that is accessed through the logically named .format() method on the string object.
My first example can be provided as: 'Project %s% is completed except for format '('spam cooker', 'switch') (where I just replaced project_name and change_list with some silly literal strings... Variables will work just as well).
The new style documentation of string formatting is covered in quite a large scale, common string operation: string formatting - Python 3.4.8 and on a site dedicated to purpose: pyformat.info: using % and .format() for the very best!
The syntax of new style formatting aims to be similar to the modern template rendering engine. Python also supports a simple template rendering feature that was introduced in version 2.4 as documented in template strings.
There are also some world-class template rendering and management systems for Python, including Jinja2, Cheetah3, Genshi and incredibly high performance Irritants, among many others. Most of these are used extensively in the framework of web applications to dynamically generate HTML (and possibly CSS).
Conclusion, '%' is just a string. But it's a string that's often being used with python old (C-language inspired) string formatting operator. There are many other string formatting tokens (replaceable parameters) and there are some other options, which are included in Python standard libraries and are available as extension modules for more sophisticated string formatting and template rendering.
