这就是一个人如何找到最好的学生:

def by_total_grade(name):
    return sum(grades[name])

best_student = max(grades, key=by_total_grade)

完整示例:

grades = {
    "Alex": [3, 7, 11, 10, 8],
    "Ben": [6, 12, 4, 9, 9],
    "Сarla": [5, 10, 7, 5, 9],
}

best_student = max(grades, key=lambda k: sum(grades[k]))
best_grades = grades[best_student]

print(
    f"Best student {best_student}, "
    f"max score {max(best_grades)}, "
    f"min score {min(best_grades)}."
)

输出:

Best student Ben, max score 12, min score 4.

正如@jim提到的,文件组织被描述为 here .为便于发现而复制:

对于python模块,典型的布局是:

Lib/<module>.py
Modules/_<module>.c (if there’s also a C accelerator module)
Lib/test/test_<module>.py
Doc/library/<module>.rst

对于仅扩展模块,典型布局为:

Modules/<module>module.c
Lib/test/test_<module>.py
Doc/library/<module>.rst

对于内置类型,典型布局为:

Objects/<builtin>object.c
Lib/test/test_<builtin>.py
Doc/library/stdtypes.rst

对于内置功能,典型布局为:

Python/bltinmodule.c
Lib/test/test_builtin.py
Doc/library/functions.rst

一些例外情况:

builtin type int is at Objects/longobject.c
builtin type str is at Objects/unicodeobject.c
builtin module sys is at Python/sysmodule.c
builtin module marshal is at Python/marshal.c
Windows-only module winreg is at PC/winreg.c
