Write a CSV file from a dict or a DataFrame. import pandas as pd d = {'a': (1, 101), 'b': (2, 202), 'c': (3, 303)} pd.DataFrame.from_dict(d, orient="index") df.to_csv("data.csv") Read a CSV file as a DataFrame and convert it to a dict: df = pd.read_csv("data.csv&qu...

One can describe a line in arbitrary dimensions as X = A + t*D where A and D are both vectors of suitably many dimensions. So in 2d this would be x = Ax + t*Dx y = Ay + t*Dy Now as t assumes any real value, this equation will produce all points along the line. The representation is not uniq...
