## NumPy: Array Object Exercise-100 with Solution

Write a NumPy program to take values from a source array and put them at specified indices of another array.

Sample Solution:

Python Code:

``````import numpy as np
x = np.array([10, 10, 20, 30, 30], float)
print(x)
print("Put 0 and 40 in first and fifth position of the above array")
y = np.array([0, 40, 60], float)
x.put([0, 4], y)
print("Array x, after putting two values:")
print(x)
```
```

Sample Output:

```[ 10.  10.  20.  30.  30.]
Put 0 and 40 in first and fifth position of the above array
Array x after put two values:
[  0.  10.  20.  30.  40.]
```
