如何读取我的 exel 表中的特定数据并从读取的每个数据集创建一个图？ （Python）

Question

Here is the code that I have so far:

import numpy as np

import pandas as pd

import csv 


file = r'C:\Users\Tiago Costa\Desktop\Senior Year - 2019.2020\ME 130\Coronovirus Datasets\time_series_2019-ncov-Confirmed.xlsx'

data = pd.ExcelFile(file)

print(data.sheet_names)

['Worksheet']

df = data.parse('Worksheet')

df.info

df.head(483) 

I was wondering how I would be able to only extract the number of confirmed cases for China, Italy, Germany, Iran and USA, and then plot that data as a function of time.

I was going to be using this: https://pythonprogramming.net/loading-file-data-matplotlib-tutorial/ as a reference to create my plots when I got to that point.

Thank you!

You don't need to convert it into .xlsx file first, because we can use .read_csv() . Then you can use .isin() to filter which countries you want to take.

data = pd.read_csv('time_series_2019-ncov-Confirmed.csv')

countries = ['China', 'Italy', 'Germany', 'Iran', 'USA']
filtered_data = data[data['Country/Region'].isin(countries)]
