# Python: Create random vector of size 15 and replace the maximum value by -1

## Python NumPy: Random Exercise-11 with Solution

Write a Python program to create random vector of size 15 and replace the maximum value by -1.

Sample Solution :-

Python Code :

``````import numpy as np
x = np.random.random(15)
print("Original array:")
print(x)
x[x.argmax()] = -1
print("Maximum value replaced by -1:")
print(x)
``````

Sample Output:

```Original array:
[ 0.04921181  0.83545304  0.4394982   0.81889845  0.8022234   0.46176053
0.95785815  0.86968759  0.35100099  0.00107607  0.4330148   0.56632168
0.57764716  0.09226267  0.01710047]
Maximum value replaced by -1:
[ 0.04921181  0.83545304  0.4394982   0.81889845  0.8022234   0.46176053
-1.          0.86968759  0.35100099  0.00107607  0.4330148   0.56632168
0.57764716  0.09226267  0.01710047]
