Step-by-Step Solution
Solution:
Step 1: Identify the correct numpy method for type conversion
The method to convert array types isastype().Step 2: Apply
Usingastype(bool)to convert integers to booleanastype(bool)converts zeros to False and non-zeros to True.Final Answer:
arr.astype(bool) -> Option BQuick Check:
Conversion method = astype(bool) [OK]
Quick Trick: Use astype(bool) to convert numeric arrays to boolean [OK]
Common Mistakes:
- Using non-existent np.to_bool()
- Trying np.bool_() as a function
- Confusing with np.boolarray() which doesn't exist
