使用 Python 从 CSV 文件中的指定行和列中提取值。 无法使用 CSV 模块或 pandas 模块

Question

I have been provided with a.csv file, which has data on covid19. It is in the form of:

district | country   |    date1      |      date2     |    date3     |etc
victoria | australia |1 case         | 3 cases        |7 cases       | etc

It is a fairly large file, with 263 rows of countries/districts, and 150 columns of dates.

The program needs to be able to take in an input district , country , and date and print out the number of COVID cases in that location as of that date. (print the value of a specified row and column of a CSV file)

We have been instructed not to use the CSV module or the pandas module. I am having trouble understanding where to start. I will add my attempted solutions to this question as I go along. Not looking for a complete solution,but any ideas that I could try would be appreciated.

Answer 1

This is what I finally did to solve it. It works perfectly. for reference the data file I am using is: https://portland-my.sharepoint.com/:x:/g/personal/msharma8-c_ad_cityu_edu_hk/ES7eUlPURzxOqTmRLmcxVEMBtemkKQzLcKD6U6SlbX2-_Q?e=tc5aJF

# for the purpose of this answer I preset the country, province, and date
country = 'Australia'
province = 'New South Wales'
date = '3/10/2020'


with open('covid19.csv', 'r') as f:
    final_list = []
    list0 = f.readline().split(',')
    for line in f:
        if line.split(',')[0] == province:
            final_list = line.split(',')
    dict1 = dict(zip(list0,final_list))

print dict1[date]

I will use the same logic to finish the solution.
