NumPy - Array Data Types

Given a NumPy array of byte strings:

arr = np.array([b'abc', b'defg', b'hi'], dtype='S4')

How can you convert it to an array of Unicode strings without losing data?

Aarr.astype('U')

Barr.astype('S')

Carr.astype('U3')

Darr.astype('O')

Step-by-Step Solution

Solution:

Step 1: Understand byte to Unicode conversion
To convert byte strings to Unicode strings, use astype with dtype='U'.
Step 2: Avoid fixed length truncation
Using 'U' without length lets NumPy choose sufficient length to avoid data loss.
Final Answer:
arr.astype('U') -> Option A
Quick Check:
Use astype('U') to convert bytes to Unicode safely [OK]

Quick Trick: astype('U') converts byte strings to Unicode without truncation [OK]
