# Solve TypeError: only integer scalar arrays can be converted to a scalar index – The Crazy Programmer

In this article we will go through the Type Error: only integer scalar arrays can be converted to a scalar index and what causes this error and how can we overcome this error and get some changes in the code so that we can get the proper solution to resolve it. This normally tells about that when we are trying to convert a simple array into a scalar index. The other reason why this error comes is that when we are trying to concatenate and that time we are not passing tuple or list for concatenation and this becomes a major problem.

In the examples we are taking we are trying to concatenate two arrays by function then the function will always concatenate two or more arrays of the same type as always. Concatenation is always done row-wise and column-wise and by default it always takes row-wise.

### Case 1:

Suppose we are taking two arrays which are having the fruits name and then we are trying to concatenate the two arrays and for the concatenation function we are assigning other variables.

When we are trying to concatenate, we are getting an error as we need to convert array1 and array2 into tuple or list.

Output:

#### Solution:

To solve this error we will convert both the arrya1 and array2 into Tuple for concatenation so that the Tuple function will run the code without giving any error. Here the output is the list and we got the solution to remove the error and the revised code.

Now we have assigned tuple for concatenation then we are getting the output.

Output:

### Case 2

Suppose we are taking a particular list in which we are assigning some range and then we are doing some indexing operation so that we can get the random choice of the spices.

But when we are running this code then we are getting the error.

Output:

#### Solution:

To solve this error we are trying to convert the simple array into numpy array. Here the output is the list and we got the solution to remove the error and the revised code.

Output:

### Conclusion

As we have seen two cases above in which first we are given two arrays and when we are assigning the tuple then we are getting the output for the error only integer scalar arrays can be converted into scalar index. We will have to see whether we have assigned the tuple or list for the arrays for the concatenation as the list catenation can be done for the arrays.

For the next case, we have to convert the simple array to numpy array for the running of code error free. This way we are solving the error and the error most occurs for the row-wise arrays concatenation done normally in the python codes. And lastly, about the error, we have to see that by a single numpy.concatenate() method we get the error removed and for converting the arrays we use np.array () by which error gets removed.
