Python uses the + operator for string concatenation. Python uses the * operator for duplicating a string a specified number of times. The @ infix operator is intended to be used by libraries such as NumPy for matrix multiplication. [104] [105] The syntax :=, called the "walrus operator", was introduced in Python 3.8. It assigns values to ...
In Java and Python 3.11+, [40] quantifiers may be made possessive by appending a plus sign, which disables backing off (in a backtracking engine), even if doing so would allow the overall match to succeed: [41] While the regex ".*" applied to the string
Any such symbol can be called a decimal mark, decimal marker, or decimal sign. Symbol-specific names are also used; decimal point and decimal comma refer to a dot (either baseline or middle ) and comma respectively, when it is used as a decimal separator; these are the usual terms used in English, [ 1 ] [ 2 ] [ 3 ] with the aforementioned ...

In some languages (e.g. Pascal) only one type is allowed, in some (e.g. C and its derivatives) both are used with different meanings and in others (e.g. Python) both are used interchangeably. In some languages, if it is desired to include the same quotation marks used to delimit a string inside the string, the quotation marks are doubled.
C++ string literals, like those of C, do not consider the character encoding of the text within them: they are merely a sequence of bytes, and the C++ string class follows the same principle. Although source code can (since C++11) request an encoding for a literal, the compiler does not attempt to validate that the chosen encoding of the source ...
