The ternary operator can also be viewed as a binary map operation. In R—and other languages with literal expression tuples—one can simulate the ternary operator with something like the R expression c (expr1, expr2)[1 + condition] (this idiom is slightly more natural in languages with 0-origin subscripts).
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 ...
The American video platform YouTube implemented a like and dislike button on these pages in March 2010, part of a major redesign of the site. This served as a replacement for their five-star rating system; [1] YouTube's designers found the previous system ineffective because the options to rate a video between two and four stars were rarely ...
In September 2012, YouTube launched its first app for the iPhone, following the decision to drop YouTube as one of the preloaded apps in the iPhone 5 and iOS 6 operating system. [112] According to GlobalWebIndex , YouTube was used by 35% of smartphone users between April and June 2013, making it the third-most used app. [ 113 ]
Python 3.8 introduced assignment expressions, but uses the walrus operator := instead of a regular equal sign (=) to avoid bugs which simply confuse == with =. [ 13 ] Another disadvantage appears in C++ when comparing non-basic types as the == is an operator and there may not be a suitable overloaded operator function defined.
Economists are keeping a close eye on inflation and labor reports amid speculation as to timing of future cuts to the Fed rate, with inflation data indicating a continued decline from a peak of 9. ...

These include numerical equality (e.g., 5 = 5) and inequalities (e.g., 4 ≥ 3). In programming languages that include a distinct boolean data type in their type system, like Pascal, Ada, Python or Java, these operators usually evaluate to true or false, depending on if the conditional relationship between the two operands holds or not.
