## NumPy: Basic Exercise-20 with Solution

Write a NumPy program to create a 3X4 array using and iterate over it.

Sample Solution :

Python Code :

``````import numpy as np
a = np.arange(10,22).reshape((3, 4))
print("Original array:")
print(a)
print("Each element of the array is:")
for x in np.nditer(a):
print(x,end=" ")
``````

Sample Output:

```Original array:
[[10 11 12 13]
[14 15 16 17]
[18 19 20 21]]
Each element of the array is:
10 11 12 13 14 15 16 17 18 19 20 21
```

## Python: Tips of the Day

Checks if the given number falls within the given range.

Example:

```def tips_range(n, start, end = 0):
return start <= n <= end if end >= start else end <= n <= start
print(tips_range(2, 4, 6))
print(tips_range(4, 8))
print(tips_range(1, 3, 5))
print(tips_range(1, 3))
```

Output:

```False
True
False
True
```
