Python——读写Excel文件

import xlrd
import xlwt
import re

# 读取excel文件的数据
def read_xlsx():
workbook = xlrd.open_workbook('11.xlsx')
booksheet = workbook.sheet_by_name('Sheet1')
p = list()
for row in range(booksheet.nrows):
row_data = []
for col in range(booksheet.ncols):
cel = booksheet.cell(row, col)
val = cel.value
try:
val = cel.value
val = re.sub(r'\s+', '', val)
except:
pass

if type(val) == float:
val = int(val)
else:
val = str(val)
row_data.append(val)
p.append(row_data)

return p

# 将数据写入到exdel文件中，并保存
def write_xlsx(data):
book = xlwt.Workbook(encoding='utf-8', style_compression=0)
sheet = book.add_sheet('test', cell_overwrite_ok=True)
# 其中的test是这张表的名字,cell_overwrite_ok，表示是否可以覆盖单元格，其实是Worksheet实例化的一个参数，默认值是False
# 向表test中添加数据
p = 0
for ii in data_list:
p += 1
print(ii)
for k in range(len(ii)):
sheet.write(p-1, k, ii[k])
print(ii[k])
# 最后，将以上操作保存到指定的Excel文件中
book.save(r'test.xls')  # 在字符串前加r，声明为raw字符串，这样就不会处理其中的转义了。否则，可能会报错
