Question

我有代码，它可以工作，但它不会生成它应该生成的图形。 我安装了 matplotlib。

import matplotlib.pyplot as plt


def weight_reduction():
    current_weight = float(input("Enter your current weight (in pounds): "))
    desired_weight = float(input("Enter your desired weight (in pounds): "))
    weight_loss = current_weight - desired_weight
    dietary_habits = float(input("Enter your current caloric intake (in calories): "))
    exercise = float(input("Enter your current exercise level (1-5): "))
    daily_deficit = dietary_habits - exercise
    try:
        days = int(input("Enter the number of days you would like to track your weight loss: "))
    except ValueError:
        print("Please enter a valid number of days.")
        days = int(input("Enter the number of days you would like to track your weight loss: "))
    weight_loss_per_day = weight_loss / days
    daily_caloric_intake = dietary_habits - weight_loss_per_day * 3500 / 7
    x = [i for i in range(days)]
    y = [current_weight - i * weight_loss_per_day for i in range(days)]
    plt.plot(x, y)
    plt.xlabel("Days")
    plt.ylabel("Weight (in pounds)")
    plt.title("Weight Reduction Progress")
    plt.show()

我尝试了代码并期望得到一个图表。

这里有一个建议：在定义你的 function weight_reduction之后，无意中调用它。 我假设您刚刚定义但未调用 function。

所以首先像你已经做的那样定义你的 function ：

import matplotlib.pyplot as plt

def weight_reduction():
   ...
   ...
   plt.show()

然后在 function 定义下方调用您定义的 function（您告诉程序执行您声明的步骤）：

weight_reduction()

如果您已经尝试过此操作，请在您的问题中提供更多信息。
