A random walk is a stochastic process that describes a path that consists of a succession of random steps on some mathematical space such as the integers. The following Python code generates three 2-dimensional random walks and plots them.

隨機游動（random walk）是一種隨機過程（stochastic process），它描述了在某些數(shù)學空間（如整數(shù)）上由一系列隨機步驟組成的隨機游動。以下的 Python 代碼生成三個二維隨機游動并繪制它們。
