从名称表中提取值，以形成熊猫数据框

Question

我想按名称从表中获取价值。我的桌子是

school = [['Jason',100],
            ['Alice',87.89],
            ['Mary',68]]

school = pd.DataFrame(school, columns=['Name','Grade'],dtype=float)

我想返回'Jason'的成绩。我试过school ['Jason']返回100，但它不起作用。

如何通过从表中调用名称来返回值？对于任何帮助和提示将不胜感激。

Answer 1

这将起作用：

grades_of_jason = school[school['Name'] == Jason]['Grade'] # filter for rows with name = json, then get grade of those rows

print(list(grades_of_jason)[0]) # get first item of this series
100
