让我们从这里开始构建

import matplotlib.pyplot as plt

def draw_scatterplot(x_values, y_values):

    plt.scatter(x_values, y_values, s=20)

    plt.title("Scatter Plot")

    plt.xlabel("x values")

    plt.ylabel("y values")

    plt.show()

const seconds = 3600

const minutes = seconds / 60

const hours = minutes / 60

const days = hours / 24

const weeks = days / 7

const months = days / 30

const years = months / 12

      return func(n int) int {

          if v, ok := cache[n]; ok {

              return v

          }

          cache[n] = fn(n)

          return cache[n]

      }
