# Python NumPy: Create an array of (3, 4) shape, multiply every element value by 3 and display the new array

## Python NumPy: Array Object Exercise-73 with Solution

Write a Python program to create an array of (3, 4) shape, multiply every element value by 3 and display the new array.

Sample Solution:-

Python Code:

``````import numpy as np
x= np.arange(12).reshape(3, 4)
print("Original array elements:")
print(x)
for a in np.nditer(x, op_flags=['readwrite']):
a[...] = 3 * a
print("New array elements:")
print(x)
```
```

Sample Output:

```Original array elements:
[[ 0  1  2  3]
[ 4  5  6  7]
[ 8  9 10 11]]
New array elements:
[[ 0  3  6  9]
[12 15 18 21]
[24 27 30 33]]
```

Python Code Editor:

```import numpy as np
x= np.arange(12).reshape(3, 4)
print("Original array elements:")
print(x)
for a in np.nditer(x, op_flags=['readwrite']):
a[...] = 3 * a
print("New array elements:")
print(x)```
