Question

1. ______________ errors occur during program execution.
2. ______________ errors occur when the programming code breaks the rules of the programming language.
3. ______________ errors occur when the programs behavior deviates from what is expected to happen.
4. fixing your programs errors is also known as ______________
5. what is the symbol that is used to \comment out\ code in python? ______________
6. strike - through / scratch out the invalid variables names:

user - name
student_name
valid!
dataset2025
2nd_place
_totalscore
age2
is_invalid

1. evaluate the expression: 38 8 6 → ______________
2. if you are given the variable num, how would you write num to the power 7? num**7
3. write a program that prompts the user to input the radius of a circle. calculate and output the area of the circle. your output should use the format: \area = #######\ hint: the area of a circle can be calculated with the formula π*r²

Explanation:

1. Runtime errors occur during program execution.
2. Syntax errors occur when code breaks language - rules.
3. Logic errors occur when program behavior deviates from expectations.
4. Fixing program errors is called debugging.
5. In Python, the '#' symbol is used to comment out code.
6. In Python, variable names cannot have hyphens (user - name is invalid), and cannot start with a number (2nd_place is invalid).
7. In Python, 38 % 6 is the modulus operation, 38 divided by 6 gives a quotient of 6 and a remainder of 2.
8. In Python, num to the power of 7 is written as num**7.
9. Here is the Python code:

r = float(input("Please enter the radius of the circle: "))
area = 3.14 * r * r
print(f"Area = {area}")

Answer:

1. Runtime
2. Syntax
3. Logic
4. Debugging
5. #
6. user - name, 2nd_place
7. 2
8. num**7
9. ```python

r = float(input("Please enter the radius of the circle: "))
area = 3.14 r r
print(f"Area = {area}")
