我如何根据 pandas 中特定列的用户输入获得列的总和

Question

import json import requests import pandas as pd def get_additonal_data(): import pandas as pd file_path = '/Users/CIS5357/Assignments/' data = file_path + 'grades.csv' df_grades = pd.read_csv(data) print (df_grades) return df_grades def do_functions(df_grades): import pandas as pd user_input_grade = input(str("enter the grade: ")) Print_grades = df_grades.at[user_input_grade].sum() print(Print_grades) df_grades = get_additonal_data() do_functions(df_grades)

Answer 1

import pandas as pd
import requests

file_path = '/Users/CIS5357/Assignments/'
data = file_path + 'grades.csv'
df_grades = pd.read_csv(data)
user_input_grade = input("enter the grade: ")
Print_grades = df_grades[user_input_grade].sum()
print(Print_grades)
