TypeError: array() takes from 1 to 2 positional arguments but 9 were given in Python
Dung Do Tien Mar 26 2022 786
I have a small block code with Python basic I practiced with the array using NumPy package.
I have created an array of 2 dimensions and I want to loop and print it. Like this
# Import the numpy library
import numpy as np
# Declaring and Initializing the one Dimension Array
snack = np.array([34,1],[34,2],[34,3],[34,4],[34,5],[34,6],[34,7],[34,8],[34,9])
# Indexing and accessing array as 2D causes IndexError
for x in snack:
print(x[0][1]) But when running the code above I got an error TypeError: array() takes from 1 to 2 positional arguments but 9 were given.
Traceback (most recent call last):
File "main.py", line 5, in <module>
snack = np.array([34,1],[34,2],[34,3],[34,4],[34,5],[34,6],[34,7],[34,8],[34,9])
TypeError: array() takes from 1 to 2 positional arguments but 9 were given I'm using Python 3.9.9 and running on Windows 11 64bit.
Do you have any idea for me?
Thank you so much.

You have got 2 mistakes
1.You created the wrong array, please change:snack = np.array([34,1],[34,2],[34,3],[34,4],[34,5],[34,6],[34,7],[34,8],[34,9])To
snack = np.array([[34,1],[34,2],[34,3],[34,4],[34,5],[34,6],[34,7],[34,8],[34,9]])2.When you loop an array 2D, each item of it is 1D so you have to change:print(x[0][1])To
print(x[0]) #OR print(x[1])Below is the full code for you:
# Import the numpy library import numpy as np # Declaring and Initializing the one Dimension Array snack = np.array([[34,1],[34,2],[34,3],[34,4],[34,5],[34,6],[34,7],[34,8],[34,9]]) # Indexing and accessing array as 2D causes IndexError for x in snack: print(x[1])#Output
1 2 3 4 5 6 7 8 9
