python（读写excel）

首先安装第三方库

---

pip install xlrd xlwt

XLRD

---

import xlrd

book = xlrd.open_workbook('demo.xlsx')
print(book.sheets())  # 获取excel中全部sheet

sheet = book.sheet_by_index(0)  # 获取excel中的第一个sheet
print(sheet.nrows, sheet.ncols)  # 获取sheet的行数和列数
print(sheet.cell(0, 0))  # 获取具体的cell，根据行号和列号，可以获得唯一的cell

cell = sheet.cell(0, 0)

print(cell.ctype)  # xlrd.XL_CELL_TEXT 值为1 文本类型
print(xlrd.XL_CELL_TEXT, xlrd.XL_CELL_NUMBER)

print(cell.value)  # 打印cell中的值

cell2 = sheet.cell(1, 1)
print(cell2.value)

# ROW
print(sheet.row(1))  # 获取第一行的内容：返回一个list，[text:'李雷1', number:60.0, number:70.0, number:69.0]
print(sheet.row_values(1))  # 获取第一行的值，返回一个list，['李雷1', 60.0, 70.0, 69.0]
print(sheet.row_values(1, 0, 4))  # 类似切片的操作，参数：row, startInx, endInx ，返回一个list：[70.0, 69.0]

# COLUMN
print(sheet.col(2))
print(sheet.col_values(2))
print(sheet.col_values(2, 0, 4))

# sheet.put_cell(rowx, colx, ctype, value, xf_index)
# xf_index: 字体，对齐，一般设置为None即可

XLWT

---

import xlwt

wbook = xlwt.Workbook()
wsheet = wbook.add_sheet('sheet1')
wsheet.write(r, c, rsheet.cell_value(r, c), style)
wbook.save('output.xlsx')

CODE

---

import xlrd
import xlwt

rbook = xlrd.open_workbook('demo.xlsx')
rsheet = rbook.sheet_by_index(0)
nc = rsheet.ncols

# 添加一个cell
rsheet.put_cell(0, nc, xlrd.XL_CELL_TEXT, u'总分', None)

for row in range(1, rsheet.nrows):
    t = sum(rsheet.row_values(row, 1, nc))  # 计算每一行的分数之和
    rsheet.put_cell(row, nc, xlrd.XL_CELL_NUMBER, t, None)  # 添加一个cell，在总分的列上

wbook = xlwt.Workbook()
wsheet = wbook.add_sheet(rsheet.name)
style = xlwt.easyxf('align: vertical center, horizontal center')

for r in range(rsheet.nrows):
    for c in range(rsheet.ncols):
        wsheet.write(r, c, rsheet.cell_value(r, c), style)

# wbook.save('output.xlsx')  注意这里不要写成xlsx，在个别机器上可能会打不开，保存为xls即可
wbook.save('output.xls')
