# TypeError: Field elements must be 2- or 3-tuples, got ‘5.0’

We Are Going To Discuss About TypeError: Field elements must be 2- or 3-tuples, got ‘5.0’. So lets Start this Python Article.

## TypeError: Field elements must be 2- or 3-tuples, got ‘5.0’

1. How to solve TypeError: Field elements must be 2- or 3-tuples, got '5.0'

It would help to know what you are trying to achieve with this code.
Assuming you are trying to create a 2D array with numpy – you need to make sure your dimensions are correct (first row with 3 element and second row with 2 element cannot make a 2D array).
And you need another [] around to make 2D array. Something like this –
`import numpy as np a = np.array([[8.0,7.0,6.0],[5.0,4.0,3.0]]) print(a)`

## Solution 2

There are two mistakes here,

i. another element has to be inserted into the second array / removed from the first array,

ii. both of them have to be passed as first argument i.e. enclosed in braces.

Rewriting the same:

``````import numpy as np
a = np.array(([8.0,7.0,6.0],[5.0,4.0,3.0]))
print(a)
``````
