使用熊猫或csv模块将值写入csv文件中的给定文件

Question

Is there any way you can write value to specific place in given .csv file using pandas or csv module?

I have tried using csv_reader to read the file and find a line which fits my requirements though I couldn't figure out a way to switch value which is in the file to mine.

What I am trying to achieve here is that I have a spreadsheet of names and values. I am using JSON to update the values from the server and after that I want to update my spreadsheet also.

The latest solution which I came up with was to create separate sheet from which I will get updated data, but this one is not working, though there is no sequence in which the dict is written to the file.

def updateSheet(fileName, aValues):
    with open(fileName+".csv") as workingSheet:
        writer = csv.DictWriter(workingSheet,aValues.keys())
        writer.writeheader()
        writer.writerow(aValues)

I will appreciate any guidance and tips.

You can try this way to operate the specified csv file

import pandas as pd  
a = ['one','two','three']  
b = [1,2,3]  
english_column = pd.Series(a, name='english')  
number_column = pd.Series(b, name='number')  
predictions = pd.concat([english_column, number_column], axis=1)   
save = pd.DataFrame({'english':a,'number':b})  
save.to_csv('b.csv',index=False,sep=',')
