table me number of student count per block kaise kare

mera program:Create csv file exam(sid,sname, seatno, blocknumber) using writer object with 10 records. Read this file and count students per block

First open file in read mode " r " and then you can count students per block by using " for loop ".

Ex:

block_count = { } with open("student.csv","r") as f: reader = csv.reader(f) next(reader)

for row in reader:
    block = row[3]
    if block in block_count:
        block_count[block] += 1
    else:
        block_count[block] = 1
