如何使这段 Python 代码工作？

Question

我正在 Replit 上制作一个项目，该项目赚钱，而不是在现实生活中。我希望 'wheat_seads'、'melon_seeds'、'pumpkin_seeds'、'wheat'、'melon'、'pumpkin' 在功能内外可用，并在不同功能中进行更改。我试图将这些变量放入和取出“farm_command”以删除“语法错误”，但它不起作用。如果你也可以，改进这段代码......

from replit import db


#This function is when 'help' command is run
def help_command():
  print("So you need help...")
  print("I am happy to help!")

  print("1. 'help'")
  print("2. 'farm'")
  print("3. 'harvest'")

#This functon is when 'farm' command is run
def farm_command():
  global wheat_seeds = 1
  global melon_seeds = 1
  global pumpkin_seeds = 1
  global wheat = 0
  global melon = 0
  global pumpkin = 0

  
  print("What seed do you want to farm?")
  farm_seed = input("Seed: ")
  farm_seed = farm_seed.lower()

  if farm_seed == "wheat_seeds":
    print("You planted " + wheat_seeds + " wheat seed/s")
    wheat_seeds -= wheat_seeds
    
    
  


#The user's cash amount
db["User"] = {
  "wallet":0,
  "bank":0
}

#This is the users inventory
inventory = [wheat_seeds, melon_seeds, pumpkin_seeds, wheat, melon, pumpkin]

#This is prompted to ask the user what command should be run
command = input("Command: ")

#This checks which command is inputted and runs the respective command
if command == "help":
  help_command()
elif command == "farm":
  farm_command()

定义全局变量时不能直接赋值。 试试这样：

全球小麦种子
小麦种子 = 1
等等……
