![]() The format of the string should be clear from the example. The user is told the function takes a string and returns an integer. Now type help(arithmetic_partial_sum): > help(arithmetic_partial_sum)Īrithmetic_partial_sum(series: str) -> int Beside numbers, other types of values can be summed as well: functions, vectors, matrices, polynomials and, in general, elements of any type of mathematical objects on which an operation denoted. :param series: A string representing the arithmetic series to solve In mathematics, summation is the addition of a sequence of any kind of numbers, called addends or summands the result is their sum or total. For example (adding Python 3.6 type hints as well): def arithmetic_partial_sum(series:str) -> int: """docstrings""" should tell a user how to use the function. Even the formula is not particularly helpful. relations can be used to put the quadratic formula and the formula for a cubic equation. Help on function arithmetic_partial_sum in module _main_: Examples are Mathematica and the CAS on the TI - 89 calculator. For example: > help(arithmetic_partial_sum) Arithmetic Sequence Geometric Sequence Harmonic Sequence Recursive Sequence Calculator. The """docstrings""" for arithmetic_partial_sum() and geometric_partial_sum() appear unhelpful. Recursive Sequence Calculator makes it easy for you to Recursive Sequence. ![]() Why not just retrieve the last term? def find_an(parsed_series): You should convert the terms to floating-point values, not integers: a1 = float(series)įind_an() assumes \$a_n\$ is immediately after the '.' term, so will fail with: arithmetic_partial_sum("3+7+11+15+.+95+99") G_SERIES = f"3+1+")įile ".\partial_sum.py", line 63, in geometric_partial_sum Return str(Fraction(S).limit_denominator()) Returns the partial sum of the geometric series :param series: Arithmetic series to solve Returns the partial sum of an arithmetic series :param parsed_series: The series to be analyzed This is a program that calculates arithmetic and geometricįinds an in the passed parsed arithmetic series I'd like feedback on anything possible, since I intend on writing a cheatsheet that encapsulates all PreCalculus equations. I've written a small program that calculates Arithmetic and Geometric Partial Sums.
