基于Python与Discord Webhooks的游戏项目：如何计算变量总和？

Hey there! Let's walk through exactly how to get that sum calculated and integrated into your project. Here's a step-by-step breakdown tailored to your use case:

1. First, Make Sure Your Values Are Numbers #

When scraping data from web pages, the values you get for robux and robux2 are almost always strings (even if they look like numbers). If you try adding them directly, you'll just concatenate the strings instead of getting a mathematical sum. So first, convert them to integers (or floats if you're dealing with decimals):

# Example: Assume these are the scraped string values
robux = "1250"
robux2 = "750"

# Convert to integers (use float() instead if you need decimal support)
robux_num = int(robux)
robux2_num = int(robux2)

Quick Cleanup Tip #

If your scraped values have commas (like "1,250"), you'll need to strip those first before converting:

robux = robux.replace(",", "")
robux2 = robux2.replace(",", "")

2. Calculate the Total #

This part is straightforward—just add the two numeric variables together:

total_robux = robux_num + robux2_num
print(f"Total Robux: {total_robux}")  # Outputs "Total Robux: 2000"

3. Send the Result via Discord Webhook #

To push this total to your Discord channel using a webhook, use Python's requests library (you'll need to install it first with pip install requests if you haven't already):

import requests

# Replace with your actual Discord webhook URL
DISCORD_WEBHOOK_URL = "your_webhook_url_here"

# Build the payload to send to Discord
payload = {
    "content": f"📊 Calculated Total Robux: {total_robux}"
}

# Send the POST request
response = requests.post(DISCORD_WEBHOOK_URL, json=payload)

# Verify the request succeeded
if response.status_code == 204:
    print("Total successfully sent to Discord!")
else:
    print(f"Oops, something went wrong. Status code: {response.status_code}")

Bonus: Handle Edge Cases #

To avoid errors if your scrape doesn't find one of the values, add a quick check before calculating:

if 'robux_num' in locals() and 'robux2_num' in locals():
    total_robux = robux_num + robux2_num
else:
    print("Error: One or both Robux values couldn't be scraped!")
