Why does 1 print as 1. in np.array([1, 2.5, 3])?
Short answer. One value is a decimal, so the dtype becomes float64 for all values.
What does a.shape give for three values?
(3,).
Remember
| dtype: one type for all |
| Maths works value by value |
One decimal changes a whole NumPy array. How? Shape shows three values. One is a decimal, so d type is float. One prints as one point. Star two doubles each value. D type is one type for all values. Maths works value by value.
