[Solved] Find the mistake in this code:import numpy as np arr = np.array([1, 2, 3]) arr[0] = 'a' print(arr) — Ans: TypeError because array elements must be numbers | SciPy

SciPy - Basics and Scientific Computing

Find the mistake in this code:

import numpy as np
arr = np.array([1, 2, 3])
arr[0] = 'a'
print(arr)

ANo error, prints ['a' 2 3]

BTypeError because array elements must be numbers

CSyntaxError due to wrong assignment

DValueError due to shape mismatch

Step-by-Step Solution

Solution:

Step 1: Understand NumPy array data types
NumPy arrays have fixed data types; here it's integers.
Step 2: Assigning a string to an integer array
Trying to assign 'a' causes a TypeError because 'a' is not a number.
Final Answer:
TypeError because array elements must be numbers -> Option B
Quick Check:
Assigning wrong type = TypeError [OK]

Quick Trick: NumPy arrays require consistent data types [OK]
