这是我正在使用的代码，但现在我想添加一个名为类号的新变量，并将学生分数保存到他们的班级。如果一个新学生在哪里参加测验他们的分数也应该保存，他们应该能够查看以前学生的分数。我尝试通过写这个来做到这一点，但我不知道如何使用搁置功能或我是否应该使用它。我知道有类似的问题已经回答，但我不理解他们请帮助我，这是我尝试开始，但我不知道如何继续。

您可以尝试字典。
class_x_scores = {}
class_x_scores[name] = score
最后，您可以将这些dicts保存到文件中：
f = open(class_x_scores,'a') # a for adding newlines to the file without cleaning information
for name in class_x_scores:
f.write(" The score of "+name + " is "+class_x_scores[name])# any format you prefer
f.close()

您应该使用pandas：
from pandas import DataFrame as df
d = df({'Student name': ['John', 'Joe', 'Lilly'], 'Score': [5.6, 2.7, 3.4]})
d.save('filename')
d.load('filename')
print d

我如何保存分数？
这只是意味着你想拥有一个非常简单的数据存储......可能是
是什么让你停止使用上述任何文件。？
