## Divide Array into Parts in Python

Dividing arrays into parts is a common task in programming. In Python, there are different ways to achieve this. Here are some ways to divide an array into parts:

### Method 1: Using Slicing

One way to divide an array into parts in Python is by using slicing. Slicing is a way to extract a portion of a string, list, or tuple.

```
array = [1, 2, 3, 4, 5, 6, 7, 8, 9]
n = 3
result = []
for i in range(0, len(array), n):
result.append(array[i:i + n])
print(result)
```

In this code, we first define an array and the number of parts we want to divide it into. We then create an empty list called "result" to store the divided parts. We use a for loop to iterate through the array and slice it into parts using the range function. We use the append method to add each sliced part to the "result" list. Finally, we print the "result" list.

### Method 2: Using numpy.array_split()

Another way to divide an array into parts in Python is by using the numpy library's array_split() function.

```
import numpy as np
array = [1, 2, 3, 4, 5, 6, 7, 8, 9]
n = 3
result = np.array_split(array, n)
print(result)
```

In this code, we first import the numpy library. We then define an array and the number of parts we want to divide it into. We use the array_split() function to divide the array into parts and store the result in the "result" variable. Finally, we print the "result" variable.

### Method 3: Using List Comprehension

Another way to divide an array into parts in Python is by using list comprehension.

```
array = [1, 2, 3, 4, 5, 6, 7, 8, 9]
n = 3
result = [array[i:i + n] for i in range(0, len(array), n)]
print(result)
```

In this code, we first define an array and the number of parts we want to divide it into. We use list comprehension to slice the array into parts using the range function. Finally, we print the "result" list.

Overall, these are three different methods to divide an array into parts in Python. Depending on the context and requirements of your program, one method may be more suitable than others.
