获取空白CSV行的百分比

import csv

def get_blank_row_percentage(csv_file):
    total_rows = 0
    blank_rows = 0

    with open(csv_file, 'r') as file:
        csv_reader = csv.reader(file)
        for row in csv_reader:
            total_rows += 1
            if all(cell.strip() == '' for cell in row):
                blank_rows += 1

    if total_rows == 0:
        return 0
    else:
        blank_row_percentage = (blank_rows / total_rows) * 100
        return blank_row_percentage

# 示例用法
csv_file = 'example.csv'
percentage = get_blank_row_percentage(csv_file)
print(f"空白行的百分比为：{percentage}%")
