I get the error message:

Traceback (most recent call last):
  File "main.py", line 5, in <module>
    print(x[0,3])
IndexError: too many indices

The problem appears when I have declared a single dimensional array using numpy library array:

# Code with error

# Importing the numpy library
import numpy as np

# Declaring and Initializing the one Dimension Array
x = np.array([212,312,2,12,124,142,12])

# Printing the result
print(x[0,3])

I’ve tried to fix it for some days but have not resolved it yet. Can someone suggest a relevant solution to fix this error?

    The cause: This error happens when you try to access the elements of a one-dimensional numpy array as a two dimensional array.

    The solution: To fix this problem, double-check the dimensions you’re using, as well as the dimensions you’re declaring and initializing as the following:

    # Code without errors

# Importing the numpy library
import numpy as np

# Declaring and initializing the one dimension array
x = np.array([212,312,2,12,124,142,12])

# To check the dimension of the array
print("Shape of the array = ",np.shape(x));

# Printing the result
print(x[0])

    Ouput:

    Shape of the array = (7,)
212
