Hello Guys. I'm a newbie in Python 3.8.2. I want to concat two arrays and I used concatenate() method of numpy package. See below:
# import numpy
import numpy
# Create array
lstColor1st = numpy.array(['Black', 'Blue', 'Green', 'Orange'])
lstColor2nd = numpy.array(['Red', 'Yellow'])
# Concatenate array lstColor1st & lstColor2nd
combindArr = numpy.concatenate(lstColor1st, lstColor2nd)
print(combindArr)
But when I run it I get an exception TypeError: only integer scalar arrays can be converted to a scalar index.
Traceback (most recent call last):
File "main.py", line 9, in <module>
combindArr = numpy.concatenate(lstColor1st, lstColor2nd)
File "<__array_function__ internals>", line 5, in concatenate
TypeError: only integer scalar arrays can be converted to a scalar index
How can I fix it?
Have 1 answer(s) found.

To solve this error you need to convert array 1 and array 2 in to tuple or list. See an example:
# import numpy import numpy # Create array lstColor1st = numpy.array(['Black', 'Blue', 'Green', 'Orange']) lstColor2nd = numpy.array(['Red', 'Yellow']) # Concatenate array ar1 & ar2 combindArr = numpy.concatenate((lstColor1st, lstColor2nd)) print(combindArr)OR
# import numpy import numpy # Create array lstColor1st = numpy.array(['Black', 'Blue', 'Green', 'Orange']) lstColor2nd = numpy.array(['Red', 'Yellow']) # Concatenate array ar1 & ar2 combindArr = numpy.concatenate([lstColor1st, lstColor2nd]) print(combindArr)#Output
['Black' 'Blue' 'Green' 'Orange' 'Red' 'Yellow']
