How to Create a Sequence of Linearly Increasing Values with Numpy Arange?
• Last Updated : 21 Apr, 2021

In this article, we are going to create a sequence of linearly increasing values with Numpy arange() function.

### Getting Started

By using arange() function, we can create a sequence of linearly increasing values. This method returns an array with evenly spaced elements as per the interval. The interval mentioned is half opened i.e. [Start, Stop)

Syntax: numpy.arange(start, stop, step)

Parameters:

• start is the starting value
• stop is the ending value
• step is a linear increment value with in the given range. It is optional. By default, it is 1.

Return Type:

• Return an array of elements

For example:

`numpy.arange(1,10,3)  # array([1,4,7])`

Here, we have given a range from 1 to 10(start = 1 and stop = 10) but we specified step=3. That means it skips every 3 elements in a range. So In this way, we can increase linearity in data.

Example 1:

Create elements within range with 3-step linearly.

## Python3

 `# importing numpy module ` `import` `numpy as np ` ` `  `# create an elements from 1  ` `# to 10 with 3 step linearity ` `print``(np.arange(``1``, ``10``, ``3``)) ` ` `  `# create an elements from 1  ` `# to 20 with 3 step linearity ` `print``(np.arange(``1``, ``20``, ``3``)) ` ` `  `# create an elements from 1  ` `# to 30 with 3 step linearity ` `print``(np.arange(``1``, ``30``, ``3``)) ` ` `  `# create an elements from 1  ` `# to 40 with 3 step linearity ` `print``(np.arange(``1``, ``40``, ``3``)) ` ` `  `# create an elements from 1  ` `# to 50 with 3 step linearity ` `print``(np.arange(``1``, ``50``, ``3``)) `

Output: Example 2:

Create elements within range with 5-step linearly.

## Python3

 `#importing numpy module ` `import` `numpy as np ` ` `  `#create an elements from 1 to ` `# 10 with 5 step linearity ` `print``(np.arange(``1``,``10``,``5``)) ` ` `  `#create an elements from 1 to ` `# 20 with 5 step linearity ` `print``(np.arange(``1``,``20``,``5``)) ` ` `  `#create an elements from 1 to  ` `# 30 with 5 step linearity ` `print``(np.arange(``1``,``30``,``5``)) ` ` `  `#create an elements from 1 to ` `# 40 with 5 step linearity ` `print``(np.arange(``1``,``40``,``5``)) ` ` `  `#create an elements from 1 to ` `# 50 with 5 step linearity ` `print``(np.arange(``1``,``50``,``5``))`

Output: Example 3:

Create elements within the range of 34 to 50 with 5-step linearly.

## Python3

 `#importing numpy module ` `import` `numpy as np ` ` `  `#create an elements from 34 to 50 with 4 step linearity ` `print``(np.arange(``34``,``50``,``5``)) `

Output:

`[34 39 44 49]`
