Question

I have the code, it works but it does not produce the graph it is supposed to. I have matplotlib installed.

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()

I tried the code and expected a graph.

Answer 1

Here is a suggestion: After defining your function weight_reduction , call it without intendation. I assume you have just defined but not called the function.

So at first define your function as you already did:

import matplotlib.pyplot as plt

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

And then call the function you defined (you tell the program to execute the steps you declared) just below the function definition:

weight_reduction()

In case you alrady did try this, please provide more information in your question.
