The NOT operator. E.g., NOT TRUE evaluates to FALSE while NOT FALSE evaluates to TRUE.

How can you explain reverse polish notation in simple words?
Reverse Polish Notation (RPN) is a system where expressions are evaluated from left to right, with no precedence, with operators stated following the operands. A typical RPN expression might be ab+c*, which in infix means (a+b)*c. (Infix is our "standard" system which we use when writing programs) Note that the infix expression required parenthesis to override operator precedence, but the RPN expression did not. If you said in infix a+b*c, the RPN equivalent would be abc*+. The value of RPN is that it is easy to build a stack machine that processes the expression. Each time you encounter an operand, you push it on the stack. Each time you encounter an operator, you process it, replacing the top two elements of the stack with the result (for binary operators), or replacing the top element of the stack with the result (for unary operators). RPN is often used in compiler design.
An electric motor is a generator in reverse meaning that it can turn electricity into?
An electrical motor generator in reverse means that it can turn the electrical energy to mechanical and kinetic energy.
What is Meaning of diode rating?
There are two diode ratings. One is the forward current rating, and the other is the reverse breakdown voltage rating. The forward current rating is the maximum current that the diode can conduct before failing, and the reverse breakdown voltage rating is the maximum reverse voltage that can be applied before failing. Of course, the reverse voltage rating has a different meaning in a zener diode, but this answer applies to ordinary diodes.
How is Boolean used in python?
Python has two constant objects, True and False and a bool() function. The bool() function simply casts its argument to one of the two Boolean objects. All integral types (integers) will implicitly cast to True or False, such that the value zero is always False and non-zero is always True. Floating point types can also be implicitly cast (such that 0.0 is always False) however floating point values are approximations and should never be used implicitly. Instead, use comparison operators to perform an explicit cast: if x == 0.0: # do something All the comparison operators return True or False, as do all the logic operators (and, or and not). However, it is never necessary to compare an expression with the True object: if x == True: The above can be reduced to the more efficient: if x: Where x cannot be implicitly cast to a Boolean constant, use the bool() function to perform an explicit cast: if bool(x): If you need to reverse the logic, you might use the following: if bool (x) == False: However, it is arguably more readable to use the not logic operator instead: if not (bool (x)): You can experiment with Boolean types through the bool function: bool ('') # False bool ('a string') # True bool ([]) # False bool ([1,2,3]) # True bool (0) # False bool (1) # True bool (0.0) # False bool (42.0) # True bool (False) # False bool (True) # True Note that the last two are redundant casts.

When a pre increment is followed by a post increment?
You cannot follow a prefix increment with a postfix increment. int x = 40; int y = ++x++; // error This has to be an error because the postfix operator has higher precedence than the prefix operator. Thus the above code is equivalent to: int x = 40; int y = ++(x++); // error The expression (x++) is evaluated first. This increments x to 41 but the expression evaluates to 40 (the original value of x). Thus the prefix operator is essentially trying to evaluate the expression ++40 rather than ++x. This cannot work because the value 40 is not a modifiable lvalue. It has to be modifiable because we want to increment the value and return a reference to the modified value. But there's nothing to refer to here. The value is temporary and will fall from scope immediately after we use it. That is, the prefix operator may well be able to increment the temporary value to 41, but that value immediately falls from scope. With nothing to refer to, the prefix expression cannot be evaluated. The only way we can use both operators together is if we reverse the precedence using parenthesis: int x = 40; int y = (++x)++; Now the prefix operator is evaluated first, returning a reference to x which (now) holds the value 41. The postfix operator then increments x to 42 but returns the original value of 41 which is then assigned to y. Thus when all statements have been executed, y holds the value 41 while x holds the value 42.
