NumPy - Creating Arrays
Which of these is the correct syntax to create an array from 2 to 6 (excluding 6) with step 1 using
np.arange()?Which of these is the correct syntax to create an array from 2 to 6 (excluding 6) with step 1 using np.arange()?
easy📝 Syntax Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Check start, stop, and step order
Start should be less than stop for positive step; step cannot be zero.Step 2: Validate each option
np.arange(2, 6, 1) uses start=2, stop=6, step=1 correctly. np.arange(6, 2, 1) reverses start and stop. np.arange(2, 7) sets stop=7, producing [2 3 4 5 6] which includes 6. np.arange(2, 6, 0) has step=0 which is invalid.Final Answer:
np.arange(2, 6, 1) -> Option DQuick Check:
Start=2, stop=6, step=1 is correct syntax [OK]
Quick Trick: Step must not be zero; start < stop for positive step [OK]
Common Mistakes:
- Using zero as step value
- Reversing start and stop values
- Using wrong stop value
