Python中如何将字典键值对转为字符串并生成指定列表？

You can easily convert the key-value pairs of your dictionary into the desired list using a list comprehension in Python—it’s concise and readable. Here’s how:

# Your original dictionary
name_dict = {"John": "Doe", "Jane": "Smith", "Jack": "Poland"}

# Convert to the target list
full_names = [f"{first} {last}" for first, last in name_dict.items()]

print(full_names)
# Output: ["John Doe", "Jane Smith", "Jack Poland"]

Breakdown of the code: #

• name_dict.items() iterates over each key-value pair in the dictionary, returning tuples like ("John", "Doe")
• The f-string f"{first} {last}" combines the key (first name) and value (last name) with a space in between
• The list comprehension wraps this logic to collect all the combined strings into a new list

If you prefer a more explicit (though less concise) approach, you could use a standard for loop instead:

full_names = []
for first, last in name_dict.items():
    full_names.append(f"{first} {last}")

Either method will give you exactly the list you’re looking for.
