# Python NumPy: Create an array of ones and an array of zeros

## Python NumPy: Array Object Exercise-34 with Solution

Write a Python program to create an array of ones and an array of zeros.

Sample Solution:-

Python Code:

``````import numpy as np
print("Create an array of zeros")
x = np.zeros((1,2))
print("Default type is float")
print(x)
print("Type changes to int")
x = np.zeros((1,2), dtype = np.int)
print(x)
print("Create an array of ones")
y= np.ones((1,2))
print("Default type is float")
print(y)
print("Type changes to int")
y = np.ones((1,2), dtype = np.int)
print(y)
```
```

Sample Output:

```Create an array of zeros
Default type is float
[[ 0.  0.]]
Type changes to int
[[0 0]]
Create an array of ones
Default type is float
[[ 1.  1.]]
Type changes to int
[[1 1]]
```

Python Code Editor:

```import numpy as np
print("Create an array of zeros")
x = np.zeros((1,2))
print("Default type is float")
print(x)
print("Type changes to int")
x = np.zeros((1,2), dtype = np.int)
print(x)
print("Create an array of ones")
y= np.ones((1,2))
print("Default type is float")
print(y)
print("Type changes to int")
y = np.ones((1,2), dtype = np.int)
print(y)```
