如何在PyCharm中为多变量添加多个if条件（板球装备计算程序）

Hey there! Since you're just starting out with PyCharm and programming, let's break this down into simple, easy-to-follow steps. I'll walk you through writing a program that meets your requirements, with explanations so you understand each part.

First, let's formalize the requirements we have:

• Calculate total equipment cost for 3 new cricket players
• Each player gets knee pads, batting gloves, and a T-shirt (we need to ask for their T-shirt size)
• Sum up all costs to get the final total

Let's assign realistic base prices to each item (you can adjust these numbers to match actual costs):

• Knee pads: $50 per pair
• Batting gloves: $40 per pair
• T-shirt: $30 each (we'll assume size doesn't affect cost for now, but we can adjust this later if needed)

Here's a complete, commented Python program you can use directly in PyCharm:

# Define fixed costs for each piece of equipment (edit these values as needed)
KNEE_PADS_COST = 50.0
BATTING_GLOVES_COST = 40.0
T_SHIRT_COST = 30.0

# Initialize total cost to 0 before calculating
total_equipment_cost = 0.0

# Loop through each of the 3 players
for player_number in range(1, 4):
    print(f"\n--- Player {player_number} ---")
    # Ask for the player's T-shirt size and store the response
    shirt_size = input("Please enter your T-shirt size (e.g., S, M, L, XL): ")
    
    # Calculate cost for this single player
    individual_player_cost = KNEE_PADS_COST + BATTING_GLOVES_COST + T_SHIRT_COST
    
    # Add this player's cost to the overall total
    total_equipment_cost += individual_player_cost
    
    # Optional: Print a breakdown for the player
    print(f"Equipment cost for Player {player_number}: ${individual_player_cost:.2f}")

# Display the final total cost
print("\n" + "="*40)
print(f"FINAL TOTAL EQUIPMENT COST: ${total_equipment_cost:.2f}")

How this program works: #

1. Constants: We use uppercase variables for fixed costs (like KNEE_PADS_COST) so they're easy to locate and update later if prices change.
2. Loop: The for loop runs exactly 3 times (for players 1, 2, 3) to process each athlete individually.
3. User Input: The input() function prompts the user to enter a T-shirt size, which we store even though it doesn't affect cost right now (you can add size-specific pricing later if needed).
4. Cost Calculation: For each player, we sum their three equipment items and add that to the running total.
5. Clean Output: We format all currency values to 2 decimal places for readability, and use separators like --- and === to make the output easy to follow.

Running this in PyCharm: #

1. Create a new Python file (File > New > Python File) and name it something like cricket_equipment_cost.py.
2. Paste the code above into the file.
3. Click the green "Run" button in the top-right corner, or right-click the file and select "Run".
4. Enter each player's size when prompted in the terminal at the bottom of the screen.

If you need to modify the code (like adding different costs for different T-shirt sizes or changing equipment items), just tweak the constants or add conditional logic—let me know if you need help with that!
