# Python NumPy: Convert the raw data in an array to a binary string and then create an array

## Python NumPy: Array Object Exercise-98 with Solution

Write a Python program to convert the raw data in an array to a binary string and then create an array.

Sample Solution:-

Python Code:

``````import numpy as np
x = np.array([10, 20, 30], float)
print("Original array:")
print(x)
s = x.tostring()
print("Binary string array:")
print(s)
print("Array using fromstring():")
y = np.fromstring(s)
print(y)
```
```

Sample Output:

```Original array:
[ 10.  20.  30.]
Binary string array:
b'\x00\x00\x00\x00\x00\x00\$@\x00\x00\x00\x00\x00\x004@\x00\x00\x00\x00\x00\x00>@'
Array using fromstring():
[ 10.  20.  30.]
```

Python Code Editor:

```import numpy as np
x = np.array([10, 20, 30], float)
print("Original array:")
print(x)
s = x.tostring()
print("Binary string array:")
print(s)
print("Array using fromstring():")
y = np.fromstring(s)
print(y)```
