matinal：Python 对Excel表进行操作

import xlrd

# 计算一个工作簿中所有Sheet表的行数
def count_book(work_book):
    workbook = xlrd.open_workbook(work_book)  # 打开excel工作薄
    sheets = workbook.sheet_names()  # 读取所有sheet表，组成list列表
    count = 0
    for sheet in sheets:
        sheet_name = workbook.sheet_by_name(sheet)  # 实例化电子表对象sheet_name
        single_count = sheet_name.nrows  # sheet_name.nrows 单个sheet表的行数
        count += single_count  # count 工作薄所有sheet的行数
    return count

excel_book = 'D:/test.xlsx'
print(count_book(excel_book))

import xlrd

# 统计sheet表中某一列数据
def count_rows(work_book):
    workbook = xlrd.open_workbook(work_book)  # 打开excel工作薄
    m = 0
    f = 0
    single_sheet = workbook.sheet_by_index(0)  # 实例化第一个sheet页,index为0
    for i in range(single_sheet.nrows):  # 遍历sheet页中每一行
        rows = single_sheet.row_values(i)  # row_values 每一行的所有数据
        if rows[2] == '男':
            m += 1
        elif rows[2] == '女':
            f += 1
    print('男生数量:', m, '女生数量:', f)

excel_book = 'D:/test.xlsx'
count_rows(excel_book)
