如何让一个函数检查多个东西

def check_multiple_things(num):
    if num % 2 == 0:
        print("The number is even.")
    else:
        print("The number is odd.")
        
    if num > 10:
        print("The number is greater than 10.")
    else:
        print("The number is not greater than 10.")

def check_multiple_things(nums):
    for num in nums:
        if num > 0:
            print(f"The number {num} is positive.")
        else:
            print(f"The number {num} is not positive.")

def check_multiple_things(strings):
    checks = {
        "string1": lambda s: 'a' in s,
        "string2": lambda s: 'b' in s,
        "string3": lambda s: 'c' in s
    }
    
    for key, value in checks.items():
        if value(strings[key]):
            print(f"The string {key} contains the required character.")
        else:
            print(f"The string {key} does not contain the required character.")
