Which statement allows more than one condition in an if statement?

What Python statement will execute one block of statements if its condition is true or another block of its condition is false?

What does === mean?

Compare equal and of same type with === The triple equals operator ( === ) returns true if both operands are of the same type and contain the same value. This definition of equality is enough for most use cases. When comparing the string “0” and the number 0 the result is false as expected.

Why is == used in Python?

== is the equality operator. It is used in true/false expressions to check whether one value is equal to another one. For example, (2 + 2) == 5 evaluates to false, since 2 + 2 = 4, and 4 is not equal to 5. The equality operator doens’t set any value, it only checks whether two values are equal.

What does != Mean in programming?
