What is not equal in coding?

The symbol used to denote inequation — when items are not equal — is a slashed equals sign “≠” (Unicode 2260). Most programming languages, limiting themselves to the ASCII character set, use ~=, != , /=, =/=, or <> to represent their boolean inequality operator.

What does [] mean in Python?

[] is an empty list. [foo.bar] is creating a new list ( [] ) with foo.bar as the first item in the list, which can then be referenced by its index: var = [foo.bar] var[0] == foo.bar # returns True.

Is Vs equal python?

There’s a subtle difference between the Python identity operator ( is ) and the equality operator ( == ). The == operator compares the value or equality of two objects, whereas the Python is operator checks whether two variables point to the same object in memory. …

Can I use != In Python?

What does && mean in coding?

logical AND operatorThe logical AND operator (&&) returns true if both operands are true and returns false otherwise. … The operands to the logical AND operator don’t need to have the same type, but they must have boolean, integral, or pointer type. The operands are commonly relational or equality expressions.

How do you use or condition in python?

How the Python or Operator Works. With the Boolean OR operator, you can connect two Boolean expressions into one compound expression. At least one subexpressions must be true for the compound expression to be considered true, and it doesn’t matter which. If both subexpressions are false, then the expression is false.
