NumPy - Creating Arrays
You want to create a smooth curve for plotting a sine wave between 0 and 2π. Which
np.linspace call is best to generate 100 points including 0 and 2π?You want to create a smooth curve for plotting a sine wave between 0 and 2π. Which np.linspace call is best to generate 100 points including 0 and 2π?

Step-by-Step Solution
Solution:
Step 1: Understand plotting needs
For smooth plotting, include both start (0) and stop (2π) points with enough samples.Step 2: Analyze options
np.linspace(0, 2*np.pi, 100, endpoint=True) generates 100 points including 2π (endpoint=True). np.linspace(0, 2*np.pi, 100, endpoint=False) excludes 2π, which may cause plot to miss endpoint. Options A, B, and D have wrong number of points or exclude endpoint.Final Answer:
np.linspace(0, 2*np.pi, 100, endpoint=True) -> Option AQuick Check:
Include endpoint for full range in plotting [OK]
Quick Trick: Use endpoint=True to include last point in plots [OK]
Common Mistakes:
- Excluding endpoint causing incomplete plots
- Using too few points for smooth curves
- Confusing number of points with step size
