# Create 1D vector values within specific range

Creating a 1D vector within a specific range can be useful in various applications, such as generating sample data for machine learning models or creating visualizations for data analysis. There is a variety of methods that you can use to create a vector containing values from 0 to 49. This thread will cover the steps needed to create a 1D vector with NumPy.
First, import NumPy:

#### 1."Indexing and Slicing":

You can use "arange" method to create a vector of random values. Following this, you can slice the desired part (10 to 49) using indexes.

#### 2. "linspace()" function:

The NumPy `linspace()` function is used to create a one-dimensional NumPy array with evenly spaced values within a specified range.
• It takes three arguments: the starting value, the ending value, and the number of values to generate.

Here’s an example of using `linspace()` to create a one-dimensional array:

#### 3. "numpy.random.randint()" function:

The NumPy `random.randint()` function is used to generate a one-dimensional NumPy array with random integer values.
• It takes three arguments: the lower limit of the range, the upper limit of the range (exclusive), and the number of integers to generate.

Here’s an example of using `random.randint()` to create a one-dimensional array:

#### 4. For "Loop" as argument:

One-dimensional NumPy array can be created using a for loop.
• The purpose of using a `for` loop inside the list comprehension is to generate a sequence of integers that will be used to populate the array.

• Then, this list is used to create the NumPy array using the `np.array()` function.

• The resulting array will contain the same sequence of integers as the list.

For example:

Using a list comprehension to create a NumPy array has advantages such as being concise, easy to modify, memory-efficient, and supporting vectorized operations.

### 5 .full() function:

The NumPy `full()` function is used to create a one-dimensional NumPy array with a specified number of elements, all initialized to a given value.
• It takes two arguments: the number of elements in the array, and the value to be used to initialize the array.

Here’s an example of using `full()` to create a one-dimensional array:
