NumPy - Array Data Types
What is the main purpose of the astype() method in NumPy?
ATo find the maximum value in a NumPy array
BTo sort the elements of a NumPy array
CTo convert the data type of a NumPy array to another type
DTo reshape the dimensions of a NumPy array
Step-by-Step Solution
Solution:

  1. Step 1: Understand the purpose of astype()

    The astype() method is used to change the data type of elements in a NumPy array.

  2. Step 2: Compare with other options

    Sorting, finding max, and reshaping are done by other methods, not astype().

  3. Final Answer:

    To convert the data type of a NumPy array to another type -> Option C

  4. Quick Check:

    astype() = convert type [OK]
Quick Trick: astype() changes array data type easily [OK]
Common Mistakes:
  • Confusing astype() with sorting or reshaping
  • Thinking astype() modifies shape
  • Assuming astype() finds max value
