如何传递每个键以检查其中是否有内容- Python

my_dict = {"key1": "value1", "key2": "", "key3": "value3"}

# 方法一：使用if语句检查每个键的值
for key in my_dict:
    if my_dict[key]:
        print(f"The key '{key}' has content.")
    else:
        print(f"The key '{key}' does not have content.")

# 方法二：使用get()方法
for key in my_dict:
    if my_dict.get(key):
        print(f"The key '{key}' has content.")
    else:
        print(f"The key '{key}' does not have content.")

# 方法三：使用in关键字
for key in my_dict:
    if key in my_dict and my_dict[key]:
        print(f"The key '{key}' has content.")
    else:
        print(f"The key '{key}' does not have content.")
