easy📝 Conceptual Q1 of 15
Step-by-Step Solution
Solution:
Step 1: Understand NumPy string types
NumPy uses numpy.str_ for Unicode strings by default when creating arrays from Python strings.Step 2: Check default behavior
When you create an array from Python strings, NumPy converts them to numpy.str_ type, which supports Unicode.Final Answer:
Unicode string type (numpy.str_) -> Option DQuick Check:
Default string type = Unicode string type (numpy.str_) [OK]
Quick Trick: NumPy defaults to Unicode strings for Python str inputs [OK]
Common Mistakes:
- Confusing byte strings with default string type
- Assuming Python native str is used inside NumPy arrays
- Thinking object dtype is default for strings
