Description
1. Write down a Python program to:
- Create a 1d array M with values ranging from 2 to 26 and print M.
- Reshape M as a 5×5 matrix and print M.
- Set the value of “inner” elements of the matrix M to 0 and print M.
- Assign M2 to the M and print M.
- Let’s call the first row of the matrix M a vector v. Calculate the magnitude of the vector v and print it.
- Hint:
- Hint: Use np.sqrt()
F. Files to submit: A Python source file (Name the file whatever you want (in English). Extension should be .py)
Expected output:

2. Write down a Python program to draw clock with a regular 12-sided polygon (정12각형).
- Set the window title to your student ID and the window size to (480,480).
- Use np.linspace() (or np.arrange()), np.cos(), np.sin() to compute the positions of vertices.
- Use a loop statement to set the positions of all vertices. Do not specify the position by calling glVertex() individually for each vertex.
- The 12 vertices should be specified counterclockwise starting from the vertex on the x-axis.
- (Hint)
- If the keys 1, 2, 3, … 9, 0, Q, W are entered, the time should be changed.
i. Hint1: Use a global variable to store which keyboard button was pressed.
ii. Hint2: Use GL_LINE_LOOP to draw clock, GL_LINES to draw hour hand(시침)
G. Files to submit: A Python source file (Name the file whatever you want (in English). Extension should be .py)
H. Expected result:
When the program starts
Press ‘1’ Press ‘2’ Press ‘3’ Press ‘4’ Press ‘5’ Press ‘6’
Press ‘7’ Press ‘8’ Press ‘9’ Press ‘10’ Press ‘Q’ Press ‘W’
