Re: i am want to read data from the csv that i wrote using python csv module but apart from filed names and row count i am unable to read rest of the data

[Rahul Gupta]

import csv
import numpy as np
with open("D:\PHD\obranking\\cell_split_demo.csv", mode='r') as csv_file:
    csv_reader = csv.DictReader(csv_file)
    print(csv_reader.fieldnames)
    col_count = print(len(csv_reader.fieldnames))
    #print(sum(1 for row in csv_file))
    row_count = 0
    
    for line in enumerate(csv_reader):
        print(line[csv_reader.fieldnames[1]])
        
@peter Otten this above one is Test10.py
@peter otten below i am posting how i created cell_split_demo.csv using test9.py
this is test9.py
import csv
import numpy as np

with open("D:\PHD\obranking\\demo.csv", mode='r') as csv_file1, 
open("D:\PHD\obranking\\demo.csv", mode='r') as csv_file2:
    csv_reader1 = csv.DictReader(csv_file1)
    csv_reader2 = csv.DictReader(csv_file2)

    #csv_contents = list(csv_reader)
    #for i in csv_contents:
        #print(i['label'])
    #print(csv_contents)

    filename = "cell_split_demo.csv"
    with open("D:\PHD\obranking\\cell_split_demo.csv", 'w') as csvfilew1:
        fields = (range(0, 300))
        csvwriter1 = csv.DictWriter(csvfilew1, fieldnames=fields)
        csvwriter1.writeheader()

        for i, row in enumerate(csv_reader1):
            Mat = np.full([1, 300], '', dtype='object')
            matrixrows = dict().fromkeys(fields)
            for j, line in enumerate(csv_reader2):
                if j != 300:
                    matrixrows[j] = []
                    if row['label'] != line['label']:
                        for k in range(1,5502):
                            if row[csv_reader1.fieldnames[k]] != 
line[csv_reader2.fieldnames[k]]:
                                if Mat[0][j] == '':
                                    Mat[0][j] = str(k)
                                else:
                                    Mat[0][j] += '#' + str(k)
                                    #print(Mat[0][j])
                                    print(i)
                                    #print(j)
                    matrixrows[j].append(Mat[0][j])
                    if j == 299:
                        csvwriter1.writerow(matrixrows)
            csv_file2.seek(0)
