如何在Python中将CSV列作为字符串读取

import csv

with open('file.csv', 'r') as file:
    reader = csv.reader(file)

column_data = []
for row in reader:
    column_data.append(row[column_index])

column_data_str = ', '.join(column_data)

import csv

def read_csv_column_as_string(file_name, column_index):
    with open(file_name, 'r') as file:
        reader = csv.reader(file)
        column_data = []
        for row in reader:
            column_data.append(row[column_index])
        column_data_str = ', '.join(column_data)
        return column_data_str

file_name = 'file.csv'
column_index = 0
column_data_str = read_csv_column_as_string(file_name, column_index)
print(column_data_str)
