Beginning Python (Video 5)

This video tutorial covers Python's basic arithmetic operators, including addition, subtraction, multiplication, exponentiation, division, and modulus. It begins with ensuring Python 3 is running, explaining how to set up the shebang line. The tutorial then delves into each operator, highlighting their usage and differences between Python 2 and 3, especially in division. The video concludes with a summary and a preview of the next topic, string manipulation.

Why is it important to ensure that your Python program is running Python 3 instead of Python 2?

• Some operators behave differently in Python 2 and 3.

• Python 2 does not support arithmetic operations.

• Python 3 has more advanced arithmetic operators.

• Python 3 is faster than Python 2.

Which symbol is used for the exponentiation operator in Python?

• ^^

• !!

• **

• ^

How can you perform integer division in Python 3?

• Using the / operator

• Using the // operator

• Using the % operator

• Using the ^ operator

What happens if you try to divide a number by zero in Python?

• Python returns infinity.

• Python ignores the operation.

• Python throws an error.

• Python returns zero.

What does the modulus operator (%) return?

• The remainder of the division

• The product of the division

• The quotient of the division

• The sum of the division

If 8 % 5 is calculated, what is the result?
