How to iterate over an array in Python 3?
And because your array length is 3, the maximum index you can use is 2. so when i = 5 you get IndexError . You should change your code into something like this: Or if you want to use indexes, you should create a range from 0 ro array length – 1. The for loop iterates over the elements of the array, not its indexes.
How to iterate and use array commands in procedures?

How to loop through the contents of an associative array?
Often you will want to loop through the contents of an associative array – without having to specify the elements explicitly. For this the array namesand array getcommands are very useful. With both you can give a (glob-style) pattern to select what elements you need:
How to loop through arrays of arrays in JavaScript?
One option would be to use recursion which works with any number of dephts. See traverse (), it’s not tested but should give a rough idea:
How does the iterator work in NumPy v1.21?
The iterator uses NumPy’s casting rules to determine whether a specific conversion is permitted. By default, it enforces ‘safe’ casting. This means, for example, that it will raise an exception if you try to treat a 64-bit float array as a 32-bit float array.
How is the index of an iterator tracked?
The index is tracked by the iterator object itself, and accessible through the index or multi_index properties, depending on what was requested. The examples below show printouts demonstrating the progression of the index:
How to signal the end of an iteration in NumPy?
However, because the nditer must copy this buffer data back to the original array once iteration is finished, you must signal when the iteration is ended, by one of two methods. You may either: used the nditer as a context manager using the with statement, and the temporary data will be written back when the context is exited.
