This is a comprehensive guide to calculating exponents in Python. You will learn different operations you can use to raise a number to a power. Besides, you will learn how the exponent notation helps write big
To raise a Legendre series to a power, use the polynomial.legendre.legpow() method in Python Numpy. The method returns the Legendre series c raised to the power pow. The argument c is a sequence of coefficients ordered from low to high. i.e., [1,2,3] is the series P_0 + 2*P_...

This method must raise a StopIteration when the stream of data is exhausted. This way, Python knows that the iteration has reached its end. By implementing these two methods in your custom classes, you’ll turn them into iterators. For example, say you want to create a class that provides...
