In Python 3, File object does not support the next() method. Instead, Python 3 has a built-in function next, which retrieves the next item from the iterator by invoking its __next__() method. If you try to call next() on a reader object in Python 3, you will raise the...
How to Solve Python ValueError: operands could not be broadcast together with shapes
In NumPy, if you try to multiply two NumPy arrays with different shapes using *, NumPy will attempt to broadcast the smaller array to the size of the larger array. If the dimensions are incompatible for broadcasting, the interpreter will throw the ValueError: operands...
How to Solve Python AttributeError: ‘str’ object has no attribute ‘decode’
In Python 2, a string is an array of bytes, like bytes in Python 3. To get a Unicode string, you can call string.decode(). However, literal strings are Unicode by default in Python 3, and you do not need to decode them. If you try to decode a string in Python 3, you...
How to Solve Python ModuleNotFoundError: No module named ‘ConfigParser’
