Concatenation simply concatenates (glues) two strings into one.

In contrast to its arithmetic sibling, the concatenation operator is not __________, i.e., "ab" + "ba" is not the same as "ba" + "ab".

If you want the + sign to be a concatenator, not an adder, you must ensure that both its arguments are integers.

The * (asterisk) sign, when applied to a string and number, becomes a __________ operator.

In replication operator (*), a number less than or equal to zero produces an empty string.

An ____________ is a symbol of the programming language, which is able to operate on the values.

Multiplication operator.

Divisional operator.

Is an integer divisional operator.

The results are always rounded.

Modulo.

Remainder left after the integer division.

Binary: 2 arguments (1 + 2)

Unary: 1 argument (-4)

What can a function do?

Where do functions come from?

The name of the function should be ________ (the name of the print function is self-evident).

A function may have:

Python functions strongly demand the presence of __________ - opening and closing ones, respectively.

If you want to deliver one or more arguments to a function, you place them inside the parentheses.

The function name along with the parentheses and argument(s), forms the ____________.

function_name(arguments)

How a function works:

1. Python checks if the name specified is legal.

2. Python checks if the function's requirements for the number of arguments allows you to invoke the function in this way.

3. Python leaves your code for a moment and jumps into the function you want to invoke. (It takes your argument(s) too)

4. the function executes its code, causes the desired effect (if any), evaluates the desired result(s) (if any) and finishes its task;

The ______ function is able to read data entered by the user and to return the same data to the running program.

Virtually all programs read and process data.

A program which doesn't get a user's input is a _____ program.

You must use the result of a function as an argument of any arithmetic operation, since it returns string.

The process of converting the value of one data type (integer, string, float, etc.) to another data type is called ____________.

Python automatically converts one data type to another data type.

Users convert the data type of an object to required data type.

We use the predefined functions like int(), float(), str(), etc to perform this type of conversion.

Explicit Type Conversion is also called ___________ because the user casts (changes) the data type of the objects.
