Once upon a time, Python introduced percent formatting.It uses "%" as a binary operator to render strings: If not provided, returns the empty string; encoding - Encoding of the given object. Python '==' operator compares the string in a character-by-character manner and returns True if the two strings are equal, otherwise, it returns False. The "%" operator is used to format a set of variables enclosed in a "tuple" (a fixed size list), together with a format string, which contains normal text together with "argument specifiers", special symbols like "%s" and "%d". Whereas when it is not found, we get a False. The modulo operator(%) is considered an arithmetic operation, along with +, –, /, *, **, //. There’s a high degree of similarity between the % operator and the printf format string functions in the C programming language. Python’s standard string formatting uses the modulo operator (the percent sign) as a special symbol to indicate different types of formats. Following is a simple example − When the above code is executed, it produces the following result − Here is the list of complete set of symbols which can be used along with % − Other supported symbols and functionality are listed in the following table − Python Sets Access Set Items … Observe that while concatenating there will be no space between the strings. A primary use case for template strings is for internationalization (i18n) since in that context, the simpler syntax and functionality makes it easier to translate than other built-in string formatting facilities in Python. Represents a hexadecimal integer using lowercase letters (a-f). Also, most programmers don’t find as intuitive as the new features in Python.
