r'...' is a byte string (in Python 2.*), ur'...' is a Unicode string (again, in Python 2.*), and any of the other three kinds of quoting also produces exactly the same types of strings (so for example r'...', r'''...''', r"...", r"""...""" are all byte strings, and so on).

The r means that the string is to be treated as a raw string, which means all escape codes will be ignored. For an example: '\n' will be treated as a newline character, while r'\n' will be treated as the characters \ followed by n.

Sep 8, 2023 · While learning Python or reading someone else's code, you may have encountered the 'u' and 'r' prefixes and raw string literals. But what do these terms mean? How do they affect our Python code? In this article, we will attemp to demystify these concepts and understand their usage in Python.

What exactly do "u" and "r" string prefixes do, and what are raw string literals? In Python, the "r" prefix before a string denotes that it is a raw string literal. This means that any backslashes () in the string are not treated as escape characters.

Jul 28, 2023 · What we need to do is just put the alphabet r before defining the string. Here r means raw string which will display the text in quotes as it is. Syntax. In this example, we defined a string using r before quotes and assigned it to a variable. Further, we have printed that variable to see the result. Output.

r before a string in python means the string should be treated as a regular expression raw string. It means that backslashes will not be translated to their meaning. ex1 = "hello\nworld" print(ex1) will print hello world. while ex2 = r"hello\nworld" print(ex) will print hello\nworld

Sep 15, 2024 · Discover how Python’s f-strings simplify string interpolation and how to use r-strings to handle raw text like file paths and regex.

Feb 22, 2022 · An ‘r’ before a string tells the Python interpreter to treat backslashes as a literal (raw) character. Normally, Python uses backslashes as escape characters. Prefacing the string definition with ‘r’ is a useful way to define a string where you need the backslash to be an actual backslash and not part of an escape code that means ...

Feb 1, 2024 · Understanding 'r' in Python. When you're just starting out with programming, encountering a single letter like 'r' in Python can be a bit mystifying. What does it mean? What does it do? Let's demystify this together. What Does 'r' Stand For? In the world of Python, 'r' stands for "raw string."

In Python, the letter ‘r’ preceding a string signifies a ‘Raw String’. This instructs the Python interpreter to interpret backslashes in the string literally, rather than as escape characters, which is the default behavior. Using the ‘r’ prefix when defining a string is particularly helpful when you want to use a backslash as an actual backslash.
