Question

是否有更简洁的方法来构建我的打印功能？

lloyd = {
    "name": "Lloyd",
    "homework": [90.0, 97.0, 75.0, 92.0],
    "quizzes": [88.0, 40.0, 94.0],
    "tests": [75.0, 90.0]
    }
alice = {
    "name": "Alice",
    "homework": [100.0, 92.0, 98.0, 100.0],
    "quizzes": [82.0, 83.0, 91.0],
    "tests": [89.0, 97.0]
    }
tyler = {
    "name": "Tyler",
    "homework": [0.0, 87.0, 75.0, 22.0],
    "quizzes": [0.0, 75.0, 78.0],
    "tests": [100.0, 100.0]
    }

students = [lloyd, alice, tyler]

for student in students:
    print student["name"]
    print student["homework"]
    print student["quizzes"]
    print student["tests"]

我尝试了以下代码，但语法错误：

for student in students:
    print student["name", "homework", "quizzes", "tests"]

如果已经回答，我道歉，但我无法找到问题。

Answer 1

我只想使用第二个for循环：

for student in students:
    for x in ("name", "homework", "quizzes", "tests"):
        print student[x]

Answer 2

您可以将每个字典传递给访问str.format的arguments by name：

for student in students:
    print("{name}\n{homework}\n{quizzes}\n{tests}".format(**student))

输出：

Lloyd
[90.0, 97.0, 75.0, 92.0]
[88.0, 40.0, 94.0]
[75.0, 90.0]
Alice
[100.0, 92.0, 98.0, 100.0]
[82.0, 83.0, 91.0]
[89.0, 97.0]
Tyler
[0.0, 87.0, 75.0, 22.0]
[0.0, 75.0, 78.0]
[100.0, 100.0]

我能以更优雅的方式打印列表数据吗？
