用Python的def函数随机生成并分类20个分别以G，D，Z，T，K开头车次构成的列表

你好！以下是用Python的def函数来随机生成并分类20个以G，D，Z，T，K开头的车次构成的列表的示例代码： ```python import random def generate_train_numbers(): train_numbers = [] prefixes = ['G', 'D', 'Z', 'T', 'K'] for _ in range(20): prefix = random.choice(prefixes) number = prefix + str(random.randint(1000, 9999)) train_numbers.append(number) # 分类 categories = {} for prefix in prefixes: categories[prefix] = [number for number in train_numbers if number.startswith(prefix)] return categories train_categories = generate_train_numbers() for prefix, numbers in train_categories.items(): print(f"以 {prefix} 开头的车次: {numbers}") ``` 运行此代码将生成包含20个车次的列表，并按照以 G、D、Z、T、K 开头进行分类。
