# Attributeerror: module ‘math’ has no attribute ‘dist’ [SOLVED]

The attributeerror: module ‘math’ has no attribute ‘dist’ typically occurs if you are using an outdated version of Python. This is because an older version of Python doesn’t have “dist” method.

If you’re not sure what this module ‘math’ has no attribute ‘dist’,” error means or how you’ll fix it, don’t worry! We’ve got your back.

The only thing you need to do is keep reading to discover the solutions you may use to troubleshoot this error. But before we get into the solution, let’s just first understand this error, so you’ll know how to address it.

## What is “math” module?

The “math” module in Python is a built-in module that contains a a set of mathematical functions or operations such as:

• sin, cos, and tan (trigonometric functions)
• log and log10 (logarithmic functions)
• mean and variance (statistical functions)

Also included the “pi” and “e,” that can be used in calculations that can be performed with ease using the module.

## What is “dist” method?

The dist() method is a function in Python that is used to calculates the Euclidean distance between two points “p” and “q,” each given as a sequence (or iterable) of coordinates.

```Syntax: math.dist(p, q)

Parameters:
p: A sequence or iterable of coordinates representing first point
q: A sequence or iterable of coordinates representing second point```

Returns: the calculated Euclidean distance between the given points.

It is calculated as the square root of the sum of the squares of the differences between the corresponding coordinates of the two points. The two points should have the same dimension.

In addition to that, the “dist” method takes two tuples (or lists) of numbers as arguments.This method is new in Python version 3.8.

## What is “attributeerror: module ‘math’ has no attribute ‘dist'”?

The attributeerror: module ‘math’ has no attribute ‘dist’ error message typically occurs when attempting to call the “dist” method from the “math” module in Python, but the “dist” method is not defined in the “math” module.

The “dist” method is a relatively new addition to the “math” module, and it was added in Python version 3.8. If you are using an earlier version of Python, you will not have access to this method.

If you are using Python 3.8 or later, you may need to check your code to ensure that you are using the correct syntax for calling the “dist” method.

## Solutions for “attributeerror: module ‘math’ has no attribute ‘dist'”

In this section, you’ll see the solutions you use to fix the module math has no attribute dist error message.

### Solution 1: Upgrade Python version

If you using an outdated version of Python certainly, you’ll get this s module ‘math’ has no attribute ‘dist’error.

You can download the latest version of Python from their official website. After installing, you can check the Python version using the following command:

``python --version``

### Solution 2: Using list comprehension and “zip” function

In this example code, we first import the “math” module as usual. Then, define two points in 3-dimensional space using tuples. Next, we check if the “dist” method is available in the “math” module using the “hasattr” function.

If the “dist” method is available, it will calculate the Euclidean distance between the two points and print out the result.

```import math

# Define two points in 3-dimensional space

sample1 = (7, 7, 7)
sample2 = (8, 8, 8)

# Check if the dist method is available in the math module

if hasattr(math, 'dist'):

# Calculate the Euclidean distance between the two points

distance = math.dist(sample1, sample2)
print(distance)
else:

# The dist method is not available, so use an alternative method

distance = math.sqrt(sum((s1 - s2) ** 2 for s1, s2 in zip(sample1, sample2)))
print(distance)```

If the “dist” method is not available (for instance, if you are using an earlier version of Python), you can use the alternative method to calculate the Euclidean distance.

In our case, we use a list comprehension and the “zip” function to calculate the sum of the squares of the differences between the corresponding coordinates of the two points.

Then take the square root of this sum using the “sqrt” function from the “math” module, and print out the result.

Output:

``1.7320508075688772``

You can also check our example code below for additional insights.

Example 1:

In this example, we use the math.dist() method using a “one-dimensional point.”

```import math

P = 10

# Coordinates of point Q
Q = -20

eDistance = math.dist([P], [Q])
print(eDistance)```

Output:

``30.0``

Example 2:

In this example, we use the math.dist() method using a “two-dimensional point.”

`import mathP1 = 15P2 = 10# Coordinates of point QQ1 = -9Q2 = -8eDistance = math.dist([P1, P2], [Q1, Q2])print(eDistance)`

Output:

``30.0``

Example 3:

In this example, we use the math.dist() method using a “three-dimensional point.”

`import mathP = [1, 2, 3]Q = [4, 5, 6]eDistance = math.dist(P, Q)print(eDistance)`

Output:

``5.196152422706632``

Example 4:

In this example, we use the math.dist() method using an “n-dimensional point.”

`import mathP = [1, 2, 3, 4, 5, 6]Q = [-7, -8, -9, 10, 11, 12]eDistance = math.dist(P, Q)print(eDistance)`

Output:

``20.396078054371138``
